Frequently asked questions

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

Scribbr’s  Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages
• 8 million publications from more than 1,700 publishers such as Springer, IEEE , Elsevier, Wiley-Blackwell, and Taylor & Francis

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. Plagiarism checks can be bought separately — prices depend on the size of your document.

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

The free report tells you if your text contains potential plagiarism and other writing issues. The premium report gives you the resources you need to review issues in detail and resolve them.

Generating your (free or premium) plagiarism report takes between 1 and 10 minutes, depending on the document size.

In that time, your document is compared to the world’s largest content database, with over 99 billion webpages and 8 million publications.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The add-on AI Detector and AI Proofreader are only available in English.

The complete list of supported languages:

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

Luckily, many papers, theses, and dissertations are also published in public databases that Scribbr does have access to.

Personalized Writing Help When You Need it

Unintentional plagiarism, grammar mistakes, and uncited sources  can turn what you thought was a good paper into a poor one. When you’re writing a paper the last thing you want is for your message to get lost due to incorrect punctuation or confusing sentence structure. You know that the great ideas in your head would make for a standout paper, if only you could get them written clearly on the page. If this struggle sounds familiar, you’re not alone.

Great ideas may be an essential part of high-quality writing, but they’re not the only component. Excellent papers and essays clearly express strong ideas with good grammar, proper punctuation, spot-on spelling, and thorough, careful citations. While this may sound like a lot, your teachers and professors are grading you on your skills as both a writer and a researcher, which means your assignments will require an ethical and attentive approach. Luckily, there is no shortage of available tools to help you along your way.

You could use a plagiarism checker free, though, these tools often lack grammatical support. Given the high stakes and rigorous requirements, the aid of a plagiarism checker without the needed support of a grammar checker could mean the difference between an “A” paper and a “C” or even “D” paper.

Thankfully, the EasyBib Plus plagiarism tool provides all-in-one support to cover all your bases. Our premium essay checker is convenient, easy to use, and includes access to a grammar and spell checker, plus a plagiarism checker. With a single scan, you’ll receive personalized feedback to help identify potentially missing citations and help improve your sentence structure, punctuation, grammar, and more.

Not sure if that noun is spelled correctly, or if the preposition at the end of your sentence is grammatically correct? The EasyBib Plus plagiarism tool is your one-stop shop to help check plagiarism, get grammatical suggestions, correct spelling and punctuation errors, and help create polished papers you can be proud to turn in. And, we haven’t told you the best part yet: you can try our tool free and scan your work for grammar suggestions right now!

A Grammar Check for Peace of Mind

You know that grammar plays a significant role in your assignments. Not only does it factor into your overall grade, but without clear and precise language, your ideas can lose their impact or might even be misunderstood entirely. Still, with so many different parts of speech and rules to learn and apply, it’s not uncommon to get them mixed up and find yourself questioning your knowledge now and again:

Can you use an adverb to modify a noun? (No. You need an adjective for that.)

Well, can you use it to modify a pronoun ? (Still no.)

What do they modify, then? (Almost everything else. Fun, right?)

Ugh. (That was an interjection .)

Does this have to be so difficult? (Nope!)

Scanning your paper with the EasyBib Plus writing tool delivers more than the basic punctuation and spell check functions that come standard in word processing programs. You’ll receive immediate, targeted feedback that can help improve the sentence structure and style of your writing. Not only can this help ensure that you don’t lose points off your grade for grammatical errors such as mismatched verb tense, but it can also help to clarify your meaning and strengthen your arguments by eliminating confusing punctuation and run-on sentences that confuse readers.

Reviewing your work to correct errors and refine the flow of your writing is a critical part of the revision process for novices and novelists alike. Even the most conscientious of wordsmiths might make mistakes, such as using a conjunctive adverb in place of a coordinating conjunction or pairing a plural determiner with an uncountable word. They likely appreciate a subscription-based or free grammar check as much as a beginning writer. That’s why the EasyBib Plus writing tool is designed for all writers, from students who are still learning the fundamentals to published professionals who get paid by the word.

The EasyBib Plus writing tool provides quick, targeted feedback that you can use to help improve your writing immediately. Also, our free resource library is available 24/7, just like the rest of our tools, to help you brush up on the areas that challenge you the most (Conjunctive what? Uncountable who?) That means you can continue to sharpen your skills and improve your writing over time, which will help make finishing your next project easier.

Ready to give your paper a boost? Sign up for EasyBib Plus or scan a paper right now for a free spell check—it’s easy!Just upload or copy and paste your paper to the online grammar check tool and, in a matter of seconds, you’ll be able to receive up to 5 feedback cards so you can begin polishing your draft.

Why is Grammar So Important, Anyway?

Why is grammar important? As long as others know what you mean, does it really matter if you use proper grammar? These are age-old questions, but the answers remain unchanged. Grammar is important for many reasons:

Communication:  Communication is about more than merely listening and talking. We communicate in myriad ways: with our voices, our mannerisms, our facial expressions, our actions, and frequently, our written words. Written communication is just as important as all the other ways we broadcast our thoughts and feelings. Unlike our other communication methods, though, written communication leaves a record. While most of us relax our style when talking to or texting friends, the fact remains that more formal venues require a more formal tone. Proper spelling, grammar, and punctuation are a necessary element of professional and academic writing, so running your work through a spelling and grammar check before you submit it is an absolute must.

Clarity:  Expressing your thoughts, ideas, and opinions is an uphill battle when you communicate them with less-than-stellar punctuation, spelling, and grammar. A missing or misplaced comma, for example, can entirely change your meaning:

• Call me Ishmael = My name is Ishmael.
• Call me, Ishmael = I want Ishmael to call me.

Spelling errors can result in similarly muddled meaning:

• Her shoes perfectly complemented her dress. = Her shoes and dress go well together.
• Her shoes perfectly complimented her dress. = Her shoes can both speak and engage in flattery.

Grammar deficiencies such as a dangling modifier yield similarly confusing results:

• I saw the girl’s purple backpack in the library. = The purple backpack belonging to the girl is in the library; I saw it.
• I saw the purple girl’s backpack in the library. = You know the girl who mysteriously turned purple? I saw her backpack in the library. This week has not been easy on her.

Credibility: Establishing your credibility is critical whether you’re writing for school or business. Proving that you can reliably communicate using proper grammar is essential to establishing and maintaining the trust of your teachers, professors, readers, customers, and colleagues.

What Happens After I Upload My Paper?

Once you upload a paper, the EasyBib Plus grammar checker scans your text and highlights grammar issues within your document so you can see it in context. For users running a grammar check and spell check using the grammar check free tool, up to the first 5 issues are shown. For subscription subscribers, all of the areas that require your review will be highlighted once the scan is complete.

No matter which version of the tool you’re using, your feedback will include detailed explanations so you can understand why the text was flagged. Other highlighted areas will include examples of how the issues can be fixed. Some will include a detailed explanation as to why the issue was flagged. This personalized feedback allows you to make an educated decision about whether to edit your text or dismiss the suggestion, so you’re always in control of your final draft.

Subscription users also have the plagiarism checker at their disposal when scanning their papers for style and grammar suggestions. Just as with our other writing tools, when you use the tool to check plagiarism, changes are never made without your review, so you are always in the driver’s seat. You can review each highlighted area as well as the sources of matching text and will always be given a choice to either accept or ignore both citation and grammar suggestions.

Whether you are a student or a professional, the EasyBib Plus tools are powerful allies that can help you improve your paper, establish credibility as a writer, and maintain an ethical writing process.

Check for Unintentional Plagiarism

Persistent use of the best grammar checker and spell checker you can find will help to shape up the style and substance of your composition. However, to ensure the integrity of your work and root out unintentional instances of academic dishonesty, you’ll also need to incorporate a subscription-based or free plagiarism checker for students.

The ability to scan your paper and check plagiarism and grammar before submitting your work is an invaluable tool for students. It’s so valuable, in fact, that students are not the only ones who consistently use this type of software.

Many teachers and professors use a service to ensure that student papers are original and include properly formatted and sourced citations for all reference materials. For some, this may be a consistent element of their grading process, while others may utilize one only when they feel there is a reason to do so.

What Exactly Does a Plagiarism Checker Do?

If you’ve used an online plagiarism checker before, you may be familiar with the process that these tools employ. For those who have never used one, it can be helpful to understand how these tools work and what you should expect as a result of using one.

The most basic free tools will scan your paper and provide you with a percentage that indicates how much of your work is original. This feature can be useful to a point, as some instructors and institutions set a percentage for the amount of similar text that is considered acceptable. This policy does not mean that they are lenient about academic dishonesty but, instead, that they recognize that similar or even matching word choice is not always an indicator of copying.

However, some schools do not tolerate any form of incremental plagiarism, period. In these institutions, “check paper for plagiarism” is likely a standard action when grading all papers.

With a free plagiarism checker, the percentage of word-for-word plagiarism in your text may be the only feedback you receive. Moreover, some of these providers may wade in unethical waters, and offer essay writing services in conjunction with their checking services. This is why many students and teachers prefer subscription-based checkers that focus on integrity, such as the EasyBib writing tools.

With our premium tools, you get more than just supporting proof that your paper is original and in your own words. Your writing is scanned for potentially matching text and areas that needs your attention is highlighted. We’ll provide you with the source of the matching text so you can review it and decide how to proceed. If you agree that a citation is needed, our citation tools and resources will provide you with the information you need to help format and insert the new sources in your text as well as your works cited page.

How Does the EasyBib Plus Online Plagiarism Checker Work?

The EasyBib Plus writing tool provides an all-in-one spell check, grammar review, and plagiarism checker that not only helps you with the paper you’re writing now but enables you to gain new knowledge and improve your writing for the future, too.

Our essay checker searches online for phrases, sentences, or passages that are similar to those in your paper. If it returns matching text, this may indicate that you have passages that are missing citations.

Just as with many checkers, our tool will tell you how many instances of matching text it finds in your paper. Our plagiarism tool is designed to do more than most free tools, however.

When a portion of your paper is flagged for review, we provide you with the source that it matches. As with our online spell check tool, you have the power to review each area and choose how to proceed. If you decide to cite the flagged text, you can review the suggested source and access our citation tools to help create a proper citation and start building a bibliography for your paper. Or, you may determine that no citation is needed, in which case it’s simple to dismiss the suggestion and continue to the next section.

If you’re unsure about how to proceed, our library of resources can help you learn more and make an educated decision. In this way, you gain more than just the ability to correct your work; over time, you can learn how to avoid plagiarism altogether.

Reasons Your Teacher May Run Your Paper Through a Plagiarism Detector

As stated previously, your teachers and professors grade papers with a fixed process that includes “check paper for plagiarism” as a standard, across-the-board action. Others may check for plagiarism only when they feel there is cause to do so. There are a few red flags that may stand out to them while reviewing a paper that would lead to their running a plagiarism check, including:

Style/Voice:  Most teachers are familiar with the style and voice that you use in your writing. While most will hope that the feedback they provide when grading your work will help you to improve problem areas over time, a paper or essay that has a dramatically different style or voice than the work you’ve previously submitted can be a red flag.

Inconsistency:  Changes in the font, font size, formality, formatting, and more may indicate that portions of a paper have been copied and pasted. If these inconsistent passages are not presented as quotations or don’t include citations, this may further indicate to your teacher that there’s plagiarism in the paper.

Old References:  Part of a well-researched paper is verifying the legitimacy and relevance of your sources. While some older references may be acceptable depending on the topic, if all of your sources are outdated, it may lead your teacher to believe that you’ve recycled your own work or someone else’s.

What is Plagiarism?

If you’re looking for a free online plagiarism checker , you’re already aware that it’s not something you want to be found in your papers. However, you may still be wondering: what does plagiarism mean? It’s a reasonable question and one that merits exploring. After all, some of the actions and circumstances that fall within the plagiarism definition come as a surprise to those who only learn that they’ve committed them after it’s too late.

So what is plagiarism? To define plagiarism in the most basic sense, you might say that it is taking someone else’s ideas and words and passing them off as your own.

If your goal is avoiding plagiarism entirely, you’ll need to go beyond the basics to thoroughly define plagiarism, recognize it, and keep clear of it. Some examples of plagiarism that students find surprising include forgotten citations, poor paraphrasing, and re-submitting your own work in whole or in part for more than one assignment. This useful article provides more help in recognizing and understanding the different forms that academic dishonesty can take.

Of course, using your own words and ideas does not count as plagiarism, nor does using common knowledge . Basically, common knowledge is information that is well known by the average person. Examples of common knowledge:

• there are 12 months in a year
• the freezing point of Celsius is zero degrees
• Socrates was a Greek philosopher

So should you only include your original thoughts and common knowledge in your papers? Of course not! Research-based assignments are meant to demonstrate your skills as a researcher, after all, as well as your ability to build upon the work of others to formulate new ideas. To avoid accidentally committing an act that falls within the plagiarism definition when you’re using another person’s words or ideas, though, you need to give them proper credit. This means you’ll need to clearly identify direct quotations or properly paraphrase them when including them in your paper.

Regardless of your approach, you’ll also need to cite your sources according to the style your professor specifies. Generally, you will use MLA format for the arts and humanities and APA format for the sciences, but it’s always best to check with your instructor when you’re unsure.

If you know what style to use but still aren’t sure how to create your citations, don’t fret! Our library of resources includes free guides to help you learn about various styles so you can properly structure and place them. And our premium tools not only help you check grammar, spelling, and originality in your papers, but subscribers also enjoy access to our citation creation tools!

What are the Different Types of Plagiarism?

In addition to the question “what is plagiarism,” you may also be wondering, “why do students plagiarize?” While some students do intentionally plagiarize because they believe they can pass off someone else’s work as their own to avoid spending time on their assignments, many others do so accidentally. They may not understand how broad the plagiarism definition is or they haven’t learned how to research and cite their sources properly. That is why it is vital to recognize plagiarism in all of its forms if you wish to ensure the integrity of your work.

Examples of plagiarism & How to prevent it

Direct plagiarism:

Intentionally copying another person’s work without including a citation that gives credit to the source. When most students are asked to identify potential plagiarism examples and behaviors, this direct and deliberate act is what they think of first.

• Prevention: If you use an idea or quote from another source, cite it in the text. Make it clear that it was not your own words. 

Incremental plagiarism:

Copying parts of another person’s work, such as phrases, sentences, or paragraphs without crediting the source. When deciding which tools to use to check a paper for plagiarism , instructors often seek out those that will identify incremental forms as well as instances of direct copying and similar phrasing.

• Prevention : Decide to either directly quote the phrases or sentences you want to use, or write a good paraphrase. In both cases, be sure to add a citation. Using a plagiarism checker could also help you identify problematic passages.

Self-plagiarism:

Academic self-plagiarism occurs when a student submits the same paper or parts of a paper for more than one assignment. When your instructors are grading your papers, they’re assessing your research and writing skills in the present. When you submit work that you completed in the past, they are both unable to evaluate your current skills and unaware that you haven’t completed the assignment.

• Prevention: Write a new paper for each assignment you’re assigned. If you feel strongly that your past work could enhance your new paper, speak to your instructor and ask for permission first.

Misleading citations:

Including a citation for a quote or idea that misrepresents the source material. This can occur if a student does not understand the reference they are citing; if a student includes a citation for a disreputable source; or the source material simply does not align with the idea or argument that the student has attributed to it.

• Prevention: Carefully review your assignment to understand it. As you research, take the time to evaluate each source notes . Remember, it’s better to have quality citations over an abundance of citations.

Invented sources:

If a reference in a student’s bibliography is found not to exist, it is considered an invented source. This may occur if a student couldn’t find a reputable source to back their argument, or if they needed to include additional references to meet the requirements of the assignment and chose to take an unethical shortcut rather than completing the required amount of research. No matter the reason, this behavior ultimately hurts them in the long run. Not only will they fail to gain the experience they need to conduct research in the future properly, but they’ll also experience significant consequences if they’re caught.

• Prevention: Set aside time to do proper research so you can find enough sources. Start creating a list of sources as you’re researching and take good notes. This will help you keep track of your sources so none are forgotten. If you do end up forgetting where a quote came from, a paper checker could help you pinpoint the original source. 

Patchwriting/Spinning:

Patchwriting is often confused with paraphrasing, but there’s a significant difference. When you paraphrase, you demonstrate that you understand the topic well enough to restate it in your own words. When you patchwrite or spin, it is more akin to a word-swapping game; there’s no need to understand the subject, merely to have access to a thesaurus so you can substitute enough synonyms to mask the source material. This can be intentional, but it may also be a result of having a poor understanding of how to paraphrase.

• Prevention: Using your own words, write down the key points of the phrase or idea, and put them together in a sentence. Be sure to include a citation as well. 

A good way to test if you’re patchwriting or paraphrasing is to remove your sources from view. If you can write about what you’ve read without looking at the source material, you likely understand it well enough to paraphrase it. If you have to review the source material with each new sentence or consult a thesaurus while writing about it (except when you’re adding direct quotations), you may be spinning your sources instead of paraphrasing them.

Academic Integrity Policies and Statements

If you’re still uncertain about what counts as plagiarism, look for your school’s/ organization’s policies on academic integrity and plagiarism. The policies of academic institutions usually cover what is considered plagiarism, the consequences of committing it, and how to avoid it. One great example is Purdue University’s Academic Integrity statement .

What are the Consequences of Plagiarism?

No matter the setting, plagiarism is not taken lightly, and the consequences can be significant. For a good reason, too! Whether in an academic or professional setting, the plagiarism consequences reflect the seriousness of the act, which is ultimately a form of theft that hurts everyone involved.

Just as with the theft of a tangible object, there can be legal punishments for plagiarism. It is, after all, a form of copyright infringement in many instances. A quick search for plagiarism articles will reveal that professional instances of intellectual theft have resulted in civil lawsuits and can even be criminally prosecuted under rare circumstances. In addition to the possible legal consequences, professionals may lose their jobs or have to start over in a new field after their acts of fraud are uncovered.

As a student, you’re likely to wonder what happens if you plagiarize in college or high school. While there will almost always be consequences for this behavior, there is no one-size-fits-all plagiarism sentence. Depending on the circumstances, academic dishonesty could result in outcomes such as:

• You might get a zero for the assignment in which the infringement occurred.
• You may receive a failing grade for the class. If it is a required course, this could leave you without enough credits to move on to the next level until you can repeat it and, in some instances, postpone graduation.
• You may be expelled from your school or university.

The academic dishonesty may be noted on your transcript, which can lead to you not getting into your preferred college, graduate school, or Ph.D. program in the future.

Nobody wants to be known as a fraud or to have a reputation for dishonesty follow them through their career. And, given the consequences that can extend beyond just their reputation, it’s no wonder that professional and academic writers who wish to avoid them take the time to understand the complete definition of plagiarism and run their work through a plagiarism checker before sending it out into the world.

Even the vigilant can fall prey to inferior tools, unfortunately. Before selecting a plagiarism checker, you should understand how they work and what they can (and cannot) detect.

How We Check for Plagiarism

When exploring how to check for plagiarism, most students and professionals conclude that including a checking tool in their revision process is not only helpful but necessary. When you consider the Herculean task of checking each line of your paper against the text of each of your resources, the benefits of a checker are clear. Moreover, this manual approach would only alert you to matching text in the sources you’re aware of, after all, and leaves the sources you haven’t reviewed untouched.

But, hang on. Why would sources you haven’t reviewed factor into your review? The answer to this lies in the plagiarism definition you learned above. What is plagiarism? It’s presenting someone else’s work or ideas as your own, intentionally or otherwise. It is not uncommon to uncover an idea while you’re researching a topic and later misremember it as your own. This might even occur years after you originally came across it.

You might wonder: how can plagiarism be avoided if you have to account for the source of every thought you include in your work? A few exceptions minimize the scope of this. Common knowledge about your topic does not need to be supported by a citation, nor does knowledge that you gained through your personal experience. Using a subscription-based or free plagiarism checker will help you locate any passages that may fall into these categories so you can review them and decide for yourself whether a citation is needed.

EasyBib Plus writing tools provide easy, convenient, and reliable support to help you find potentially missed citations and can help you improve your paper into a high-quality paper with integrity. Simply upload your paper, select the checker, then sit back and relax as the site scans your document. In mere moments, we’ll search the web for passages of similar text and highlight duplicate content for your review.

Regardless of the tools you use to help you revise and polish your work, it’s ultimately your responsibility to ensure that you’re writing and submitting ethical work. That’s why our tools go beyond the basics and require your participation. The tool never automatically makes changes to your paper, but only flags sections that may need your attention and provides you with the matching source so you can to make an educated decision.

If you find that a citation is needed, our citation tools can help you create properly formatted citations and develop a complete bibliography. And, if you review the passage and determine that the match is coincidental, you can dismiss the alert and move on to the next.

Seamless Citation Creation

Professional writers and students alike can find creating citations incredibly confusing. Nevertheless, they are an integral part of a well-written and researched paper and a requirement in almost all academic settings. But, have you ever wondered why they are so important? Citations really do have a purpose—other than driving us crazy— that make it necessary always to cite our sources.

We cite our sources for a few important reasons:

We need to give credit where credit is due. When you use a quote from someone else’s work, you need to give credit for using their words and ideas. Research is often based on the works and ideas of others. However, to include the words and ideas of another without giving them proper credit is to plagiarize, even if the act was unintentional.

In addition, showing that you’ve done proper research by including in text & parenthetical citations and a comprehensive list of sources to back up your arguments gives your work a layer of credibility that can help you earn the trust of your reader or teacher.

Readers can find the sources you used.  When you’re writing high school or undergraduate papers, your only readers may be your instructors and peers. However, including citations at every level of writing helps to ensure that anyone who reads your work can access your sources to check their accuracy, learn more about your topic, and further their own research.

Sources can take your research and learning to the next level, too. When you are conducting research on a topic, checking the works cited or annotated bibliographies prepared by your sources can lead you down new avenues in your research to further develop your ideas and help you write your papers.

Correctly utilizing citations gives strength to your thoughts and opinions. Understanding the value of citations does not, unfortunately, make them any easier to create. We know how confusing it can be, but don’t throw in the towel on learning how to cite websites in MLA , create your APA citation website references, or format your works cited —this is where we come in!

While a free online plagiarism detector may tell you how much of your work is unoriginal and may even identify the passages that meet their plagiarize definition, a premium EasyBib Plus plagiarism checker account also gives you access to our powerful citation resources and generator so you can:

Scan your papers with the plagiarism tool to check for plagiarism-free work before you submit.

Review flagged passages to determine if they meet the plagiarism definition and create unlimited citations in APA format and MLA format for anything fitting the plagiarism meaning. Need more styles ? Check out our regular citation generator for thousands of choices and free resources to help you learn how to create an APA parenthetical citation , APA book citation , APA works cited , and so much more!

Build a full bibliography for your paper right along with your parenthetical or in-text citations, which can save you hours of work along the way compared to manually creating and formatting them.

How Else Do We Help You Improve Your Paper?

The EasyBib Plus plagiarism detector helps you check your content or paper for text that may be missing a citation—which may fall within the definition of plagiarism—to help ensure you don’t accidentally plagiarize. It also includes grammar check and spelling check tools to help identify errors and suggest grammatical tweaks that could help to elevate the level of your writing.

Running a plagiarism check couldn’t be easier! Just upload your paper to the online proofreader, and in a few moments we’ll have your writing and citing suggestions. And, there’s no need to worry about your paper after it’s been scanned.

Run a Grammar and Spell Check for Free!

There’s no denying that your schoolwork can be challenging at times, and your assignments can lead to some late nights even when you’ve started them early.

Why not let our plagiarism checker free up space on your calendar by helping you revise your papers quickly and efficiently? The EasyBib Plus paper checker is your one-stop shop to check for plagiarism, create citations, spot spelling mistakes, and receive feedback on your grammar and style.

When you proofread and do a manual spelling check on work that you’ve written, you’re more likely to overlook mistakes.

There are tricks to help minimize this, such as reading your work aloud to identify poor grammar or reading each sentence backward to find spelling errors. When time is of the essence, though, these solutions aren’t the most convenient or useful options. That’s why many students seek the assistance of online tools that will run a grammar and plagiarism check on their work.

Are you asking yourself, “ How do I check my grammar online ?” We’ve got the perfect checker for you! Our advanced tools help you find and correct grammar, spelling, and punctuation mistakes.

Plagiarism Checker by Quetext

Free plagiarism checker: how it works, enter text into plagiarism detection tool.

We make it simple. Just copy and paste all content from your document into our plagiarism checker and hit the ‘Check Plagiarism’ button to get started.

Evaluate text for plagiarism

Our plagiarism detection tool uses DeepSearch™ Technology to identify any content throughout your document that might be plagiarized. We identify plagiarized content by running the text through three steps:

• 1.) Contextual Analysis
• 2.) Fuzzy Matching
• 3.) Conditional Scoring

Accurate plagiarism results

After evaluating the text against billions of internet sources, you will be provided with a plagiarism score showing the percentage of text that is an exact or near-match to existing text online.

Resolve plagiarism risk and use citations

Our ColorGrade™ feedback feature highlights exact matches vs. near-exact or “fuzzy” matches with corresponding colors. From there, you can resolve plagiarism issues by deleting or altering the at-risk copy. Or, you can use our handy “Cite Source” feature to generate citations in MLA, APA, and Chicago formats and insert the citations directly into your document.

Plagiarism Checker Benefits

Whether producing original content or verifying that of others, there’s a lot to gain from using a plagiarism checker. Accurate, automatic detection of duplicate content facilitates the copy-checking process for teachers, students, content writers, and more. Results showing the exact percentage of plagiarized content allows users to see exactly how much text has been copied and where they need to re-word.

For Teachers

Before homework can be graded for quality, it must first be confirmed as original. Our easy-to-use tool arms teachers with a simple, effective way to verify and grade students’ work. Educators at all levels can benefit from ensuring academic integrity through a comprehensive plagiarism check. From K-12, all the way through higher education, teachers are faced with the task of verifying the originality of the work of dozens, if not hundreds, of students each year. Automating this process frees teachers up to focus on the quality of work, rather than be bogged down by its originality.

For Students

While the prevalence of academic plagiarism is on the rise, much of it is arguably unintentional. A simple, yet accurate and comprehensive, plagiarism checker offers students peace of mind when submitting written content for grading. It is much easier to do a quick check for potential plagiarism before submission rather than convince a teacher after the fact that your academic integrity is not in question. And Quetext even takes checking for plagiarism a step further, helping students identify and cite the source itself with our built-in citation generator.

For Copywriters

Plagiarism risk is not restricted to academia. Anyone tasked with writing for an individual or business has an ethical and legal responsibility to produce original content. On top of that, content writers are often tasked with producing content on topics outside of their wheelhouse, leaving them reliant on the work of others for their research. Our plagiarism checker gives content writers a quick and easy method to prevent copyright infringement. Checking even lengthy pieces of writing takes only a few minutes, keeping companies’ public content in check and writers’ integrity intact.

Types of Plagiarism

It’s important to understand that plagiarism expands far beyond just copying someone else’s work word-for-word. There are several different types of plagiarism that should be avoided.

Self-Plagiarism

Many believe that, as long as they produced the work at some point in the past, they can include it in future pieces. However, even if you were the original author, that original work must be cited in order to not be flagged as plagiarism. Treat your past self as a totally separate author; be sure to include all relevant citations and quotations, the same as you would for any other source.

Patchwork Plagiarism

Patchwork plagiarism is the act of piecing together a "patchwork" of existing content to form something new. Assembling unoriginal content in this manner often involves some paraphrasing, with only slight changes. This type of plagiarism can be tricky and can certainly occur unintentionally, especially in academia. Since academic writing is largely based on the research of others, a well-meaning student can inadvertently end up plagiarizing.

Mosaic Plagiarism

Mosaic plagiarism is synonymous with patchwork plagiarism. It describes the process of loosely rearranging or restating another's work without issuing proper credit. It can occur accidentally or intentionally. For authors, mosaic plagiarism endangers their academic integrity or reputation as a writer. For those checking content originality, such as teachers, mosaic plagiarism can easily appear to be original content, which can make mosaic plagiarism especially difficult to detect manually.

Accidental Plagiarism

Plagiarism doesn’t have to be intentional to still be considered plagiarism — even in early academia, where students are just learning how to properly cite others’ work. While there may be no ill intent from the student, most schools have policies explicitly treating accidental plagiarism the same as intentional plagiarism. Students are expected to know how to properly issue credit to other authors. Similarly, content writers risk damage to their reputation if they produce plagiarized content, regardless of intent.

Plagiarism Checker FAQ

What is plagiarism.

Plagiarism is representing someone else’s work as your own. In educational contexts, there are differing definitions of plagiarism depending on the institution. Plagiarism is considered a violation of academic integrity and a breach of journalistic ethics.

What percentage of a paper can be plagiarized (or copied) and still be considered unique?

Generally speaking, similar or exact copies of another source should be kept under 15% for the total text of the article/paper/essay. As a best practice, citations should be used whenever using another source word-for-word.

What’s the difference between deliberate and accidental plagiarism?

Deliberate plagiarism is purposely copying works from books, articles, webpages, or someone else’s paper and representing it as your original work. Alternatively, accidental plagiarism occurs in a few different ways:

• Incorrectly citing another person’s works
• Failing to paraphrase another person’s works - even when citing it correctly
• Reusing your own previous papers and inadvertently representing it as a new idea

What are the consequences of plagiarism?

The consequences for plagiarizing another person’s works vary. But broadly speaking, the types of consequences can be grouped by person and profession.

Plagiarism consequences for students

Maintaining academic integrity is a top priority for every educational institution. As already mentioned, ignorance of how to properly cite sources is not an excuse for plagiarism. It is the student’s responsibility to ensure they are submitting work that has not been plagiarized.

Failure to do so can result in disciplinary action, including an automatic failed grade, removal from a class, or expulsion from a school or university. Students who are allowed to continue at their institution following an act of plagiarism may encounter mistrust and additional scrutiny from teachers and instructors.

Plagiarism consequences for copywriters

Copywriters stake their reputation (and by extension, that of their client or company) on their writing. All copywriters must produce completely original content for their clients.

The consequences for plagiarism here are clear: Copywriters who plagiarize the content of others will quickly find it difficult to obtain paying assignments. Similar to academic situations, it is the copywriter’s own responsibility to ensure that their content is 100% original.

Plagiarism consequences for journalists

Journalists are held to exceptionally high standards of integrity in their writing. A journalist who produces plagiarized content jeopardizes the trust of their readers and publishers. Plagiarism can instantly reduce a journalist’s career by a large margin. The ethical and legal standards issued to journalists are clear: Produce original, well-cited content or find another field.

Consequences of Plagiarism

Today, copyrighted content has become a constant problem in educational institutions. Students create many assignments using a lot of research in a short period. Many schools/institutions, such as Duke University, have judicial affairs offices. They will review each case of plagiarism and fix penalties.

Most of the outcomes of plagiarism occur once the replication is caught. Institutions have noted that students who duplicate data often fail to learn research and writing skills. Once they leave the institution, all those students lose the ability to create original content because they have only cheated before.

Professional

Countless journalists, academics, writers, and creators have had their reputations damaged by plagiarism accusations. Not only do plagiarists disrupt their ongoing work by getting fired or terminated. They also find it difficult to get work in the future. A particularly egregious instance of plagiarism, or worse, can destroy a person's professional image. It also forces them to change careers to avoid the stigma of plagiarism.

Apart from all the professional and personal difficulties that may arise in certain cases, there are also legal consequences. Copying copyrighted material for profit may result in the plagiarist having to pay some financial losses. In some cases, copying data can subject the plagiarist to criminal prosecution. And the punishment can range from charges to imprisonment.

So, before submitting any content, do a plagiarism check once to see if you have copied it or not. It can protect you from all kinds of harm. You won't have to wait long for results using a duplicate content checker. You can take advantage of this plagiarism checker free and save yourself from embarrassment.

Plagiarism refers to using some other person’s ideas and information without acknowledging that specific person as the source. Similar to all other forms of theft, plagiarism also has many disadvantages associated with it.

It can take place in both intentional, when you try to pass someone’s content as your own, or unintentional when you forget to mention the source for your work correctly. In spite of the kind, piracy always has consequences when it is discovered. Mostly, the punishment of accidental copying is temporary. Because ascertaining unintentional plagiarism requires knowledge of intent, the overall prestige of the plagiarist becomes the deciding factor.

Plagiarism can occur in any shape either textual or pictorial. So we not only scan the document for the copyrights but also check the duplication for images.

You don't need a plagiarism checker, right?

You would never copy-and-paste someone else’s work, you’re great at paraphrasing, and you always keep a tidy list of your sources handy.

But what about accidental plagiarism ? It’s more common than you think! Maybe you paraphrased a little too closely, or forgot that last citation or set of quotation marks.

Even if you did it by accident, plagiarism is still a serious offense. You may fail your course, or be placed on academic probation. The risks just aren’t worth it.

Frequently asked questions

No, the Self-Plagiarism Checker does not store your document in any public database.

In addition, you can delete all your personal information and documents from the Scribbr server as soon as you’ve received your plagiarism report.

Scribbr’s Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker . This means you won’t be charged on a recurring basis – you only pay for what you use. We believe this provides you with the flexibility to use our service as frequently or infrequently as you need, without being tied to a contract or recurring fee structure.

You can find an overview of the prices per document here:

Please note that we can’t give refunds if you bought the plagiarism check thinking it was a subscription service as communication around this policy is clear throughout the order process.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages.
• 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The add-on AI Detector and AI Proofreader are only available in English.

The complete list of supported languages:

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

To cater to this, we have the Self-Plagiarism Checker at Scribbr. Just upload any document you used and start the check. You can repeat this as often as you like with all your sources. With your Plagiarism Check order, you get a free pass to use the Self-Plagiarism Checker. Simply upload them to your similarity report and let us do the rest!

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

Definition of Plagiarism

But before checking for plagiarism everyone should know, What Is Plagiarism?

“The act of pretension where you take one’s words and make them your own it can include ideas, thoughts, or any material that you can see/hear and make a copy of.”

If we talk in a legalistic manner then taking someone’s copyright and claiming it to be yours is unintentional plagiarism.

Self-Plagiarism

The concept of thinking that, self-plagiarism is only copying some other's paintings or borrowing someone else's unique idea. In my thoughts like "copying" and "borrowing" can cover the seriousness of the offense.

According to the Oxford Dictionary Plagiarism is:

“The practice of taking someone else's work or ideas and passing them off as one's own”

In precise words, plagiarism is an act of fraud. It involves both stealing someone else's artwork and lying approximately it in a while.

Prepostseo plagiarism checker is a reliable and accurate online tool that allows users like students, writers, and bloggers to check plagiarism for free. It provides quick results and comes with many useful features.

The words Limit For Our Tool is Explained Below:

What is Plagiarism?

As  Wikipedia says ,

“. ..plagiarism is the representation of another author's language, thoughts, ideas, or expressions as one's own original work. ..”

According to Merriam-Webster ,

"...t o steal and pass off (the ideas or words of another) as one's own: use (another's production) without crediting the source... "

Here is our own take on explaining plagiarism.

“Plagiarism is the act of taking someone’s content and utilizing it without giving them the due credit.”

Contrary to what many people think, plagiarism has nothing to do with permission. It doesn’t matter if any content is taken from a source without the permission of the author or not. As long as the borrowed content is properly cited and the author/source is accredited, it will not be said to be plagiarized.

It is a different matter altogether if the source or author in question has expressly prohibited the use of their content even with citations/credits. In such cases, using the content would not be proper in any capacity.

Plagiarism is an unethical act and it has many consequences. That is why it is necessary to check plagiarism in all types of content before finalizing it.

How Does Our Plagiarism Checker Work?

Our online plagiarism checker works by matching the provided input text against existing content from online sources. It then generates a plagiarism report according to the percentage of unique and plagiarized text in the content.

Prepostseo’s plagiarism tool checks for plagiarized content across online sources by using different search engines.

It is also capable of detecting paraphrased content along with exactly matching text. It identifies all types of plagiarism, i.e., incremental, patchwork, and accidental plagiarism.

How to avoid plagiarism: 10 strategies for your students

Tech Wire Asia

The International Center for Academic Integrity (ICAI) defines academic integrity as not just avoiding dishonest practices, but rather “a commitment, even in the face of adversity, to six fundamental values: honesty, trust, fairness, respect, responsibility, and courage.” And while it might feel like enough to post these high-level tenants on the wall of a classroom and move forward, it’s wholly more valuable (and complicated) to provide actionable ways to avoid plagiarism and embody these values.

There are myriad ways to support students in and outside of the classroom. And when it comes to avoiding plagiarism, many might say instantly, “Just get a plagiarism checker!” However, genuine instruction and learning goes beyond that: a successful approach to learning needs to contain guidance on areas that surround accurate research and citation; adequate time management; definition of misconduct and support if misconduct ensues.

Below are ten specific strategies for instructors that specifically support the skills students need to not simply avoid plagiarism, but to authentically learn and grow.

• Ensure students know the difference between academic integrity and plagiarism.
• Outline and define emerging trends in academic misconduct.
• Teach students how to properly cite sources in a paper.
• Support students’ development of time management skills.
• Emphasize the value of and way to paraphrase correctly.
• Clearly outline the institution’s and course’s policy on academic misconduct and AI writing usage.
• Define the steps taken after misconduct is suspected.
• Explain the concept of authentic learning.
• Describe how authentic learning can help students avoid plagiarism.
• Consider options for a plagiarism checker and an AI detection tool.

Let’s dive into this list in more detail. In the next section, you’ll find each tip framed as a question that a student might plug into a search engine (“What’s the difference between academic integrity and plagiarism?”), followed by suggestions and resources that support the development in that topic.

What is plagiarism? What is the difference between academic integrity and plagiarism?

In the classroom, it is important to have an aligned definition of plagiarism, even if it's assumed to be common knowledge. Explicit instruction for students has a measurable impact on mitigating misconduct. So to start things off, let's define plagiarism.

To plagiarize means to “steal or pass off (the ideas or words of another) as one’s own” and/or to “use (another's production) without crediting the source.” In fact, plagiarize (and plagiarism) comes from the Latin plagiarius “kidnapper.: An integral tenant of the Western world’s concept of academic integrity involves citing the original source of information, giving appropriate credit where credit is due.

Truth be told, many consider “plagiarism” and “academic integrity” to be synonymous, when in fact, they cover different aspects of similar ideas.

In a previous Turnitin blog post , we recognize that “while plagiarism is indeed an act of academic dishonesty and academic misconduct, it isn’t the entirety of academic integrity.” In fact, academic integrity really is the commitment to live by the values listed by the ICAI (above) and plagiarism, specifically, “is a subset of academic dishonesty, and one way to violate academic integrity.”

Students, then, need to understand what plagiarism is and isn’t, as well as their school’s policies on integrity and misconduct, so that they can approach their work with gusto and honesty. Instructors benefit from communicating their policies around academic integrity not just at the start of an academic semester, but throughout the year. In addition, it is worth talking with students about forms of plagiarism, which can be seen on Turnitin’s Plagiarism Spectrum 2.0 , covering twelve different types of unoriginal work, including traditional forms of plagiarism and emerging trends. Furthermore, instructors should explicitly list resources that students can turn to in times of need (tutors, office hours, citation guidelines, etc.) so that the temptation to plagiarize is lessened even more.

When students study or publish abroad, it’s worth noting that the concept of authorship and citation is deeply rooted in Western principles. There are significant cultural differences in plagiarism that need to be considered, so educators and students alike can uphold integrity as global citizens while also respecting the cultural norms of different learning communities.

What are emerging trends in academic misconduct?

There are a variety of trends in academic misconduct out there today. From contract cheating and electronic cheating devices, to word spinners and online test-banks, there is a vast world of shortcut options. There is also concern around AI Writing tools and how they may transform the landscape of academic integrity .

Some instructors may fear that by talking about shortcut solutions, they introduce the concept of plagiarism and thereby open a door for students. The opposite is true for many educators, however, who find that by discussing shortcut solutions openly and clearly communicating their plagiarism policies, students know what is expected of them and which recommended resources to turn to in times of need.

Additionally, there has been lots of meaningful discussion around the appropriate use of AI writing tools in education. Depending on the instructor’s or institution's policy around AI tools, it is of utmost importance for a student to have an understanding around expectations concerning AI for each and every assignment. And as instructors more readily utilize AI writing detection, it’s equally important to have a context within which to interpret any particular AI writing detection score . In particular, this infographic enumerates many of the variables that educators should consider when interpreting each student's AI writing score

A meaningful first step can be Turnitin’s eBook, “Emerging trends in academic integrity” for a complete look at trends in academic misconduct. This free, downloadable guide talks about how to identify cases of misconduct and mitigate them, as well as how to deliver remote assessments with integrity, which helps institutions and instructors alike to build a strong foundation of integrity for authentic learning.

How do I cite sources in a paper?

Instructors at every grade level and in every subject should cover correct citations. Referencing others’ work creates a strong association between one writer’s thinking and the perspective of other scholars in that field. According to the University of Washington (USA): “Scholarship is a conversation and scholars use citations not only to give credit to original creators and thinkers, but also to add strength and authority to their own work. By citing their sources, scholars are placing their work in a specific context to show where they ‘fit’ within the larger conversation.”

If students understand the value of citations and how to craft them in their papers , it can lead to confidence long-term in submitting their own writing and not that of others’, illustrating their own understandings, and developing their own voice in the academic space.

How can I develop time management skills?

Time management is essential to success, not only in academia, but in life. As early as possible, students should learn time management skills so that they can organize their work, schedule time to study or research, and balance their extracurricular and academic activities. When students plan ahead, there is less likelihood that they will choose shortcut solutions for assignments because they are confident in their own approach and the time required to research and revise.

If students are struggling with time management, interventions by tutors or teachers may be helpful prior to a larger assignment or exam. Online resources, too, can be helpful; Blair Fiander, founder of Blair’s Brainiacs, offers advice on how to keep motivated while studying remotely and tips for independent study and revision .

How do I paraphrase correctly?

Paraphrasing supports learning outcomes because it requires students to analyze, summarize, interpret, and restate others’ writing. It supports and strengthens research because it brings in other ideas without interrupting the flow of writing the way a direct quote sometimes does. However, if a student doesn’t know how to paraphrase information accurately or effectively, there is a greater chance that they will unintentionally plagiarize, or even seek alternative methods, including word spinners or AI writing tools to complete an assignment.

When students can read a body of text and then put it into their own words, not only do they avoid plagiarism, they also more deeply absorb complicated concepts and enhance their own thinking. Paraphrasing can often help students to feel more confidence about research they conduct and produce. Check out Turnitin’s Paraphrasing Resource Pack , a comprehensive set of ready-to-use resources for those seeking to enhance this valuable skill.

What is my school’s policy on academic misconduct and AI writing usage?

Just as roadways function better with clearly posted speed limit signs, so too, can students complete their best, original work when they understand expectations. In addition to the syllabus and rubric, which gives students a roadmap on what is needed to complete the assignment, students also need an understanding of the honor code and how a school approaches suspected misconduct.

When a student body receives education around academic misconduct, there is a significant decrease in cases of plagiarism. A 2020 study found that after 12 semesters of academic misconduct data, there was a 37.01% reduction in instances of detected plagiarism following explicit interventions on academic misconduct ( Perkins, et al. ).

Sharing a policy can take many forms. The University of South Australia provides students with a 12-page written Academic Integrity Policy that not only defines key terms, but also outlines levels of offense and their specific consequences. Kingston University in London offers a landing page that defines academic misconduct and the university’s procedures. Instructors, furthermore, should update their honor codes for online learning environments because with the increase of online instruction during the pandemic, many universities reported an uptick in misconduct.

Institutions, as mentioned above, also need to update their academic integrity policies to include AI and ideally, clearly outline what constitutes use and misuse within the charter.

All of these steps provide clear guidelines for students who need to know how to submit high quality assignments, as well as what happens if misconduct occurs.

What happens if I’m caught plagiarizing?

If a student’s assignment has suspected plagiarism, there are several things that may happen, depending your institution’s policies:

• An escalation policy, which needs to have been communicated to the students prior to any assignments, is enacted.
• Conversations between students and instructors, which could include a deep-dive into how research was conducted, how references were cited (or not cited), as well as any examples of a student’s previous work as a comparison.
• Administration or academic panel involvement (if needed).
• Next steps, be they a rewrite, a failed grade, expulsion, or other.

Plagiarism not only tarnishes the act of learning, but it can also affect a student’s or institution’s reputation, the quality and respectability of research, and the value of a diploma. And while it’s never a pleasant experience to go through this process, sometimes simply knowing there are serious penalties for misconduct deters students from seeking shortcut solutions.

Hamilton College Reference Librarian Julia Schult says, "Plagiarism isn't a bad thing simply because it's intellectual theft—although it is that. It's a bad thing because it takes the place of and prevents learning." As such, many instructors and institutions are opting for an alternative to the zero-tolerance approach when it comes to misconduct, in order to put learning back into the equation.

There is an increased desire for restorative justice which, unlike traditional punishment, looks “to see students not only learn from their mistakes, but to simultaneously re-establish their standing and give back to the institutional community” ( ICAI 2018 ). The University of Minnesota (USA) has provided a program entitled “Academic Integrity Matters” (AIM) for students who have engaged in scholastic dishonesty and accept responsibility for violating the Student Conduct Code. Based on restorative justice principles, this program offers an opportunity for students to attend facilitated meetings with community members to reflect on the importance of academic integrity. Participants and community members discuss and agree on an educational opportunity the student will complete in order to demonstrate understanding of academic integrity and move beyond the disciplinary space.

For instructors seeking restorative justice, there is an opportunity to turn plagiarism into a teachable moment , helping students to understand why there are safeguards in place to ensure original work. Furthermore, if students feel like they can fail safely , often risks are mitigated because they know that even if they make mistakes, they can rewrite, relearn, and rebuild trust to make it better in the future.

What is authentic learning?

Avoiding plagiarism is about prioritizing learning and its process above the end result. While explicit instruction and academic policies fortify academic integrity, it’s also important to nurture intrinsic motivation for learning. What is one way to help foster such intrinsic motivation in students? Authentic learning is one option.

Julia Hayden Galindo, Ed.D., from the Harvard Graduate School of Education , describes authentic learning as ”learning activities that are either carried out in real-world contexts, or have transfer to a real-world setting.” She goes on to say:

“Authentic learning tasks capture students’ attention and raise their motivation to learn because they touch on issues that are directly relevant to students’ present lives or future careers. The instructor’s role, in this mode of teaching, is to help students to make connections between their own ways of making sense of the material and the established cultural frameworks of the discipline” ( Stein et al., 2004 ).

Rooted in constructivist theory, authentic learning insists that actively engaging with problems and materials constitutes the best way to learn ( Mayo, 2010 ). As John Dewey said, “[E]ducation is not an affair of ‘telling’ and being told, but an active and constructive process” (Dewey, as cited in Mayo, 2010, p. 36). Stein, Issacs, & Andrews emphasize that authentic learning activities should have both personal and cultural relevance ( 2004 ). And as often as possible, instructors should merely be facilitators of learning, providing an environment for learning where students themselves lead the charge and engage with topics, wrestle with new ideas, engage in discussions with each other, and ultimately, dive into material that is meaningful to them on their own terms.

How does authentic learning help students avoid plagiarism?

At its core, authentic learning fosters intrinsic motivation. Instead of being driven by fear, by a higher grade, or even by approval of others, students instead work hard for themselves. They have an internal desire to try something new, make mistakes, acquire a skill, and increase their knowledge. And because it comes from within, they are less likely to seek shortcut solutions that would hinder or taint their genuine learning. If educators can foster in students such a desire to learn for its own merits, then even when under pressure or facing a deadline, a student will still seek to complete their own, original work.

• Using examples so students know how the material can be of use. Providing meaningful reasons for learning activities.
• Providing constructive feedback early and often to help students understand next steps in their learning journey, which includes positive feedback.
• Giving students control over their learning. Giving them opportunities to choose their own topics or reading lists and provide a variety of assessment formats , so they have control over how they demonstrate their understanding.

As James Lang put it in his book, Cheating Lessons: Learning from Academic Dishonesty , educators should strive to inspire students “with appeals to the intrinsic joy or beauty of the task itself.” If educators nurture an environment that feels authentic, safe, and inspiring, with clear expectations and high standards for original work, research shows that cases of misconduct are low and the caliber of learning high ( Lang, 2013 ).

How can a plagiarism checker help me?

In an academic space where students and instructors alike are seeking to avoid plagiarism and promote original thought, this question is prominent. However, it is a question that should be asked in tandem with all of the questions above, as one element of a multi-faceted approach to academic integrity. Plagiarism checkers like Turnitin Feedback Studio act as a backstop solution to academic misconduct if all of the above methods should fail.

A tool like Turnitin Feedback Studio is beneficial because it utilizes a massive database of content to determine if there are similarities between a student’s work and writing that has already been published. If instructors opt for multiple submissions , then a student can receive up to three Similarity Reports before the due date to get feedback on their writing and improve it before submitting.

Utilizing tools like Draft Coach in the writing process also upholds integrity; with Draft Coach, students can receive immediate feedback, not just on similarity, but on citations and grammar as well. From there, students can revise their writing accordingly, which not only encourages real-time learning, but also equates to real time saved by teachers grading papers on the back end.

And within Turnitin Originality, there is an AI detection feature to help educators identify when AI writing tools such as ChatGPT have been used in students’ submissions, offering insights to inform next steps.

And while choosing a plagiarism checker is helpful in a variety of ways, it is important to note that Turnitin does not detect plagiarism . Our tools, in fact, detect similarity and offer insights to support instructors and administrators making their own informed decisions about student work.

In sum: Strategies for students to avoid plagiarism

In the end, avoiding plagiarism goes beyond having a tool to check for similarity. It is a robust, holistic approach that includes foundational instruction around citations and paraphrasing; a culturally responsive curriculum that clearly defines misconduct and policies in that community; the prioritization of student wellbeing to ensure that students feel seen in the classroom .

Students, instructors, and administrators can work together to utilize these strategies and establish a culture of academic integrity where authentic learning is the goal and high-quality, original work is seen daily.

Free plagiarism checker for you to enjoy

Essay plagiarism checker free with accurate percentage.

When dealing with an academic task, a student often needs to check essay for plagiarism before submitting it to their professor. Many colleges and high schools set a certain limit on plagiarised content in essays, research papers, theses, and other academic papers. So, it's crucial to know the exact percentage of unique content to avoid any issues with your educator.

Unfortunately, a typical plagiarism checker free for students doesn't show the precise ratio of the original text in an essay. It simply states whether the whole text has any traces of plagiarism. This is utterly misleading and unhelpful. Even the simplest citation will make your text not 100% original, not to mention improper quotes and self-plagiarism. So, you'll be left with only one choice - to rewrite your essay from scratch in an attempt to get fully original content. Considering how complex and lengthy formatting rules for scholars are, crafting a 100% unique text without making a single citation or self-plagiarism mistake becomes a nearly impossible task.

That's why finding out an exact percentage of non-unique text in their paper is the number one priority for many students. And our professional online plagiarism checker can help you with that.

Are there consequences for using free plagiarism checkers?

Plagiarism is the act of copying someone else's work without proper attribution, whether intentional or not. Failing to acknowledge the author's work or presenting it as one's own is considered plagiarism. Even minor paraphrasing can result in lower grades and other severe consequences, such as expulsion from school or even damaging one's professional reputation.

It is crucial to understand the principles of academic integrity and honesty and to always check your work for plagiarism. This is especially important for students working on dissertations, theses, or other significant academic projects that require original research.

In addition to the ethical considerations, there are legal consequences for plagiarism. In some cases, it may even lead to litigation. Therefore, it is essential to be mindful of plagiarism and avoid it at all costs.

To avoid unintentional plagiarism, one should learn how to properly cite and reference sources, paraphrase effectively, and avoid copying and pasting. It is also important to use plagiarism checker tools to ensure the originality and uniqueness of one's work.

In summary, plagiarism is a serious offense that can have far-reaching consequences. It is crucial to understand its implications, adhere to academic integrity principles, and always check your work for plagiarism to avoid any negative consequences.

To further ensure your academic integrity, familiarizing yourself with different ways to avoid plagiarism can significantly enhance the originality of your work.

Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required.

How to Support Students to Avoid Plagiarism in Assignments

Avoid confusion around plagiarism in assignments. get tips on ways to support students and how to provide clear guidelines on what is (and what isn't) plagiarism..

With consequences ranging from a stern talking-to and a failing grade to getting kicked out of school entirely, it may be hard to believe that student plagiarism in assignments continues to be an issue. 

However, in some cases, students may not realize that what they’re doing qualifies as plagiarism. Schools and teachers may outline their policies in academic codes and classroom expectations, but research shows that students struggle to recognize plagiarism . 

Fortunately, there are ways to avoid confusion. Providing clear guidance around what plagiarism is and isn’t helps students avoid plagiarism in assignments and its potential consequences. 

Clearly Define Plagiarism and Its Consequences

It’s hard for students to avoid something if they don’t know exactly what it is. So, providing students with a clear definition of plagiarism and its consequences is the first step to preventing it in the classroom.

It’s all too easy to skim through a syllabus. It’s much harder to ignore a classroom discussion on the subject, especially if the phrases “failing grade” and “expulsion” are involved.

This allows students to ask questions about anything they’re unclear on and for their quieter peers, allows them to hear the answers. 

With plagiarism definitions and consequences often varying by instructor, course, and school — especially when it comes to using artificial intelligence (AI) in assignments — providing a clear explanation of expectations in each class is recommended.

Incorporate Plagiarism Assignments Into the Curriculum

Whether you’re dealing with plagiarism in high school or college , or teaching anything from English to coding , it’s worth working a few plagiarism assignments or lessons into the curriculum .

It may seem straightforward, but navigating the different types of plagiarism and learning the skills to avoid them can be complex at first.

Teaching students examples of plagiarism and proper paraphrasing skills can help them identify and reduce it in their work.

Example plagiarism assignment :

• Ask students to read a paragraph and review two passages based on the text. 
• One of the passages should show plagiarism, and the other shouldn’t. 
• The goal of the assignment? Identify the plagiarized version and explain why.

For further resources, Purdue University offers a great handout on the difference between quoting, paraphrasing, and summarizing. Then, Florida State University has some plagiarism exercises you can adapt to your school and classroom.

Teach Students How to Cite and Reference Sources

Sometimes, plagiarism is simply due to a lack of knowledge about when and how to use citations. So, whether you prefer MLA, APA, or another citation and format style, teaching students how to cite their sources properly could be all it takes to reduce cases of plagiarism in the classroom.

Lead by example. In addition to providing handouts and exercises on the subject, incorporate citations into class discussions. During a lecture , cite your sources to show students where you’re getting information and how to credit the authors.

When you repeatedly show students examples of correct citation use, it may just become second nature and reduce the cases of accidental plagiarism in the classroom.

Design Assignments That Discourage Plagiarism

If you come up with a unique assignment or one that requires submitting multiple phases, it’ll be a lot more difficult for students to get a ready-made one. 

Requiring students to submit drafts of their work at certain milestones can be particularly effective, especially if they provide reference lists at each stage.

Not only does this allow you to catch any potential plagiarism issues before submission, but it also encourages students to work on their time management skills. 

By asking students to provide outlines and drafts of their assignments, you’re helping them avoid the scramble to write a paper at the last minute. 

Encourage Students to Use Plagiarism Checkers and Let Them Know if You Use Them

While teaching students the ins and outs of plagiarism is an important part of avoiding it, it’s not always enough. Accidental plagiarism, especially when first learning, can happen. This is where a plagiarism checker comes in handy.

When students aren’t confident in their ability to identify plagiarism in their work, they can run it through a plagiarism detector to see if it flags anything. You may already be using one to assess the originality of student papers anyway, so you can walk them through the process.

If students see that their attempts at paraphrasing or summarizing are still showing up as plagiarism, they can edit their work accordingly. In this way, plagiarism checkers can help further educate students about what contributes to plagiarism and how to avoid it.

The Bottom Line: Teaching Students About Plagiarism Is Key to Avoiding It

Students may hear about plagiarism time and time again at school, but there can still be room for confusion.

Teach students about plagiarism and citations through:

• Clear definitions
• Classroom activities
• Bespoke plagiarism assignments
• Plagiarism checkers (to double-check their work)

This will help them avoid many of the issues that come along with plagiarizing assignments. 

Then, when you combine these strategies with multiphase papers and projects, you’ll encourage fantastic time management skills!

What Is Plagiarism? Definition and How to Avoid It at All Costs

July 30, 2024

• How to check for plagiarism

Plagiarism checker software

Plagiarism faqs.

Plagiarism isn’t an academic word that disappears once you graduate.

Plagiarism isn’t as simple as borrowing someone else’s work, either. In short, plagiarism is theft. Whether written, multimedia (images, videos, graphics, music), or spoken word, using someone else’s content without proper attribution to the original source falls within the realm of plagiarism. 

Many people utilize plagiarism checkers to avoid any time of funny business in their writing and double-check the legitimacy. 

What is plagiarism?

Plagiarism is the uncredited use of a person’s proprietary content that is passed off as original content by someone else.

You’ve heard about plagiarism more times than you can count but still don’t understand what the big deal is. Everyone does it, right? (No, they don’t.)

Plagiarism, though not technically illegal or criminal, can classify as a crime depending on the severity of the case. If you’re copying an essay, quotes from a book, an online resource, or the contents of your coworker’s resume, that’s considered plagiarism. However, if you’re plagiarizing something that is protected by a trademark or copyright , you could be fined, sued, charged, or even put in jail.

So, to prevent yourself from accidentally (or intentionally) plagiarizing, keep reading to learn about the examples of plagiarism and how to stop yourself from committing this morally questionable offense.

Examples of plagiarism 

The following plagiarism types are the most common yet super easy to avoid. Although many are specific to academic writing (e.g., essays and research papers), anything below is applicable to business professionals with writing-heavy job functions as well. 

1. Missing quotation marks and author attribution

Any time you use a quotation, whether it’s a couple of words, a few sentences, or a large block of text, you have to attribute the quote to the person who originally uttered (or wrote) the words you’re referencing. To do this, list the person by name and include quotation marks around any and all words belonging directly to the speaker/writer.

In the academic world, you’ll most likely be using MLA , APA, or CMS citation style guides for your classwork (unless in a specialized concentration), so make sure you know which one you’re supposed to use for your specific course.

In the professional world, simply referencing the person by name (first and last) and the work from which you are quoting will suffice. Otherwise, sticking with MLA format is always a safe choice.

2. Buying a paper from an essay writing website

Especially popular among college students facing strict deadlines for midterms and final exams that consist of an essay portion, essay writing websites might seem like a hero in disguise. These sites promise 100% original content within a certain timeframe (e.g., in 24 hours or three days, depending on how quickly you need your paper).

However, while this method might seem failsafe, many online essay-writing websites reuse essays that their essay writers had once created for someone (100% originally, as promised) and send you, the naive buyer, a copy of a previously-written paper about the topic you requested an essay for. 

Because you cannot guarantee that they have hand-crafted a brand new essay for you, you could potentially be accused of plagiarism if you turn it in and someone else had submitted it before you – even if it was at a school or institution far from yours. 

It’s not like you can go to your professor and make a claim that the paper isn’t plagiarized because you bought it brand new online. Then, not only are you a plagiarist, but you’re also a cheater. It’s not a good look.

3. Turning in someone else’s work as your own (even if they let you)

Even if you’re not a student anymore, you were at some point, meaning you definitely had friends who took a class before you did and vice versa. Many instructors stick with the same syllabus semester after semester, year after year. So much work goes into creating a syllabus that they don’t want to overhaul and create another one for the same class they’re teaching for the 12th time. 

Students are wise and know this from talking to each other. So if your friend took a class on the history of artificial intelligence in the fall semester of 2021, and you plan to take it in the spring semester of 2024, you’re already aware of the fact that there’s a 10-page final essay you’ll need to write. But you don’t like writing, and your friend got an A on their final essay, so you figure it’s been long enough that you can re-submit the paper with your name on it, and you’re good to go.

Well, not only do instructors have a pretty good memory, but they can also use plagiarism-checking websites to give them an extra layer of security in confirming the originality of your final paper.

Plus, if you get caught plagiarizing, you’ll definitely fail the paper, fail the class, and both you and your friend can be expelled for such an offense. But hey, those are the consequences of plagiarism.

4. Having somebody rewrite sections of your paper (or the whole thing)

Students who are struggling with starting or completing a paper will usually take their professor’s advice and seek help at their university’s writing center from a writing tutor. But a large number of students take the word help a bit too liberally and expect a writing tutor to, well, write their paper for them.

While writing tutors are beneficial resources for assisting in the completion of an assignment, finding more source material, or helping a writer with learning how to rework their content, tutors aren’t there to write or rewrite students’ papers.

If you ask a writing tutor to “reword” or “rephrase” a large chunk of a paper you’ve written, or ask them how they would say something with the expectation that they give you a word-for-word response that you can copy and use as your own words, that’s plagiarism.

Writing tutors should be used to enhance your own writing while helping you learn how to become a better writer. Don’t take advantage of them!

5. Using old work you previously wrote as “repurposed” content

Using an old paper you wrote for a class years ago, or an article you published on your former employer’s website and trying to pass it off as freshly written or “repurposed” content is considered self-plagiarism .

You’re probably thinking, but I can’t plagiarize myself! Well, actually, you can.

Self-plagiarism is pretty simple. If you use the exact same content you’ve previously written and try to pass it off as new or “repurposed” content, you’re self-plagiarizing. Be honest with your reader and provide them with a note indicating that this is not the first use of or publication of the content they’re reading.

And hey, if your writing is in an online format, you can even link back to your other content and grow your site traffic! 

6. Paraphrasing (without attribution)

To get around citing sources, people opt to paraphrase the content. However, there’s a fine line between paraphrasing something and usurping content that someone else wrote first. You might come across the most informational source about the topic you’re researching (and have to write about), and you think that they say what you need to say better than you ever could. So you decide to copy and paste directly from their website and change some words here and there, but keep the general idea of what they said intact.

Guess what? That’s still plagiarism.

Just because you add a few flowery words and switch the order of the text from the original source doesn’t mean you’ve created something original. To make sure you aren’t accidentally plagiarizing, give credit to the author of your original source or the website where your source material came from. You don’t have to use quotation marks because you aren’t directly quoting the source, but you should reference your source by name as a way to cite them.

7. Source misattribution

In the same way that not citing your source constitutes plagiarism, so does citing an incorrect source. Just because you read that one person said or wrote a famous quote you’ve heard a hundred times doesn’t mean that the person you heard it from actually said it first.

8. Common knowledge

Words and phrases like Abraham Lincoln’s “four score and seven years ago” or Martin Luther King, Jr.’s “I have a dream” are considered common knowledge. So yes, we all know that Lincoln gave The Gettysburg Address and that MLK Jr. gave the I Have a Dream speech ; however, you should still note the source (person) whose common words and phrases you’re using.

Simply noting “When MLK Jr. said he had a dream…” in your writing would be sufficient in this instance. Nobody’s going to confuse Lincoln or MLK Jr. with someone else, and everybody knows who they are.

How to check for plagiarism 

If you're on the receiving end of some fishy content, you may be wondering how to find out if plagiarism is involved. Here are some quick tips to keep in mind while you figure that out.

• Compare the usual quality of the writer's work.
• Utilize free plagiarism tools .
• Identify odd and dramatic changes in grammar, font, sentence structure, etc.
• Do a quick Google search.
• Look out for concepts above the level of the writer's understanding.
• Get familiar with websites commonly used for plagiarism.
• Learn more about the use of AI writing assistants .
• Invest in more comprehensive plagiarism checkers.

It's not easy to determine at first glance whether something is plagiarized or not. Plagiarism checking software save the day by automating the way you catch some wary writing.

• Allow users to upload documents or input live text
• Bring attention to content that is being flagged as potentially plagiarized 
• Identify the sources where the text may have been plagiarized from

* Below are the top five leading plagiarism checker platforms from G2’s Spring 2024 Grid® Report. Some reviews may be edited for clarity.

1. Grammarly Business

Grammarly Business is an AI-powered writing assistant that helps businesses expedite the writing process with tools like a grammar checker, plagiarism checker, citation generator, style guide, and more.

What users like best:

“I like that Grammarly provides accurate, thorough, and easy-to-understand grammar and spelling checks. It helps me to quickly identify and correct any potential errors in my writing. Additionally, it has a wide variety of helpful writing tools like punctuation checkers, synonym finders, and plagiarism detectors. Grammarly's intuitive user interface makes it easy to use, and its AI-driven technology ensures that the suggestions it makes are always reliable and up-to-date.”

- Grammarly Business Review , Eashan G .

What users dislike:

“An aspect that I've found less helpful is that sometimes it does not catch all errors in the document, which can be frustrating if I'm relying on the software to catch everything. Additionally, Grammarly Business does not have the capability to detect cultural and regional variations in the language. This means it may flag certain words or phrases that are perfectly fine to use in specific regions or cultures but not considered appropriate in others. Lastly, the price point can be quite expensive for small businesses or independent users like me, which can be a limitation for those who want to use it but do not have the budget for it.”

- Grammarly Business Review , Ivette V.

2. Turnitin

Turnitin specializes in prioritizing academic integrity in the education industry. Turnitin's most popular tool is state-of-the-art plagiarism detection which is especially helpful in online learning environments.

“I have used Turnitin for over 5 years for checking the similarity index of academic papers. The software is the coolest software for anti-plagiarism. It has a good interface that allows you to navigate easily. When you check a document for plagiarism, the software gives you a report and links to the sources of the document. It uses several colours to differentiate the sources of your paper. Its pricing is fair and flexible. It has two sections for checking the instructor version and the student version. I hope it is going to develop a feature for checking content generated by AI tools such as Moonbeam and ChatGPT.

- Turnitin Review , Lamar R.

“Like most technologies, it's not going to catch everything. Plus, some of the flagged assignments might be legitimate student work, so be sure to double-check, especially if multiple students were allowed to work together to create a thesis or topic sentences.”

- Turnitin Review , James T.

3. ProWritingAid

ProWritingAid is an all-in-one grammar checker, style editor, and plagiarism detector. It helps writers enhance their work by identifying errors, suggesting style improvements, and providing various writing metrics reports.

“I love how easy it was to integrate ProWritingAid into Word and Google Chrome. I use it all the time and don't write anything without it, from fiction novels to cover letters. The numerous features help with keeping my voice consistent and my words running smoothe.”

-  ProWritingAid Review , Sam G.

“Being an artificial intelligence, it can't replace the human eye entirely. Some of the suggestions or corrections are simply wrong, and the program won't always get the small nuances of what you've written. You still need your own judgment and knowledge for a good number of suggestions.”

-  ProWritingAid Review , Elli C.

4. PlagiarismCheck.org

PlagiarismCheck.org helps educators from K-12 and higher education identify potential plagiarism in their students' work. PlaigiarismCheck.org's detection tools help to identify paraphrasing, suspicious changes in sentence structure, grammar errors, and more. 

“I love this website! It is so helpful! I use it to check my academic papers for plagiarism every time I need to submit a paper, and it helps me feel more confident about my writing.”

- PlagiarismCheck.org Review , Shristi L.

“It's a little difficult to navigate, and there are some paywalls to get through. The price is kinda high, considering there are free versions. The site should try to monetize a different way”

- PlagiarismCheck.org Review , Kyle M.

Quetext offers a free plagiarism detection tool that is as easy to use as copy and paste. Users can download their Google Chrome extension to analyze their drafts and collect plagiarism scoring throughout the writing process.

“I like the reports and their overall plagiarism detector. I have tried to use other tools for plagiarism, but nothing came as close to Quetext. It was accurate and perfect. Really helpful, especially if you are writing a ton of documents on the internet.”

- Quetext Review , Tejas R.

“I think there is a disadvantage with Quetext where sometimes a content writer may write exact text without intention, so it may detect plagiarism. Its algorithm may mislead innovative content.”

- Quetext Review , Khursheed K.

Get Started with the Google Originality Checker

Updated on August 1, 2024

The Google Originality Checker is available in Google Assignments. It works by analyzing a submitted assignment (Doc, Slides, or other Word based files) and comparing it against items found in a general Google web search. The report it generates flags portions of the submitted assignment which are similar to items found elsewhere online. 

The Originality Checker is turned off by default , but may be turned on in any assignments using the Google Assignments (LTI 1.3). The Originality Checker is available only through this tool and is not available for any other method of assignment submission, nor is it available with Canvas Quizzes. 

When the Originality Checker is turned on, students can check the document before submitting an assignment and the instructor can run a check when providing feedback on the assignment.

Example Reports

If the Originality Checker does not find any resemblance to items found elsewhere on the internet, the report will say “no matches found”.

However, if matches are found, the Originality Checker will flag the passages and link to the relevant web matches.

Limits to the Originality Checker

While the Originality Checker that can provide some additional information to students and faculty, it also comes with risks, including normalizing cheating by communicating to students that it is expected and compromising a positive relationship with students. For a deeper dive into academic integrity and interventions that can support it, see our resource on  Fostering Academic Integrity . See below for more information on specific limits to the Originality Checker.

Plagiarism vs Referenced Quotations

Despite the option being displayed as “Check plagiarism (originality)” on an assignment, it is not recommended for plagiarism detection, but instead as a method of providing feedback on source and citation management. It is sometimes imprecise in distinguishing between directly copied passages and referenced quotations.

False Positives

“False positive” flags are possible if there is a turn of phrase that happens to resemble something the Originality Checker finds on the internet, so reports need to be reviewed with discretion. 

File Type & Language

The Originality Checker will not work on non-Google supported file formats such as PDFs, and content from sources that are not in English. Attempting to run the checker on a non-supported file format, or on a non-English document, will return a false negative, “No Matches Found,” result.

The Originality Checker is unable to determine the likelihood that the material was generated by an AI tool, such as Copilot or ChatGPT. While it has no specific AI-detection capabilities, it will flag any text that the AI quoted from an existing internet source, just as it would from a human writer.

Numerical Limit

Currently the checker may only be used by faculty five times for a single course, while students may run it three times per assignment. When a student is nearing their limit, they will receive a warning informing them of their remaining report runs.
