Customers Love Originality.ai

After testing a number of AI content detection tools, I have found Originality.ai to be one of the best on the market . And now with the ability to detect paraphrased AI content, Orignality.ai is even more powerful. It’s basically my go-to detection tool at this point.

SEO Consultant, GSQI.com

Originality.ai makes this process easy for us by providing a simple and efficient tool that ensures the content we receive meets our expectations.

Kityo Martin

Clicking Publish

I love the tool. Not only does it detect ACTUAL Al written content, but also writers who write just like Al. Great way to weed out Al and poor writing. Just because content was written by a human doesn't mean they did any better than an Al tool. We had a lot of our writers test positive for Al and they didn't use Al. What was common in all their writing was the lack of original thoughts. It was all regurgitation.

Ryan Cunningham

After doing some serious testing with Originality (which caters for the newerAl tech), I can't fool it (yet).

Founder, FatJoe

So what can we learn from this? In many cases, the tool tells the right story, even when it's nuanced, like in the case of AI content edited by humans.

Gael Breton

Founder, Authority Hacker

I realize that AI content isn't going away and with human editing, it can save time/make blog content better. That said, I've also had writers submit content that was 100% AI and never told me. A BIG no-no. This tool (Originality.ai) is what I'm using to stop that.

Frequently Asked Questions

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.

With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.

Using text comparison tools is much easier, more efficient, and more reliable than proofreading a piece of text by hand. Eliminate the risk of human error by using a tool to detect and display the text difference within seconds.

We have support for the file extensions .pdf, .docx, .odt, .doc and .txt. You can also enter your text or copy and paste text to compare.

There is never any data saved by the tool, when you hit “Upload” we are just scanning the text and pasting it into our text area so with our text compare tool, no data ever enters our servers.

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.

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.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

Why to avoid plagiarized content

Have you ever heard about Digital Millennium Copyright ? This law regulates digital intellectual property, and there is no doubt that it has changed the way the Internet world works today. In some cases, duplicating data can even cause the plagiarist having to go through some criminal prosecution where the punishment can range from charges to imprisonment. 

Nevertheless, a lot of people continue to duplicate stuff from one site and post it on theirs without citing/tagging the author. Assuming all the credit for the work that has a place with another person falls under copyright.

How to check plagiarism between two documents or URLs

You can easily use the duplicate content checker to find duplicates  between two texts or webpages. Our text comparison tool supports all popular types of documents. Don’t waste time going through comparing two documents for plagiarism manually.

• Paste plain texts or web page URLs in two boxes.  
• Press “Check” button. 
• You will get the results of the comparison in a matter of seconds.

• 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.

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.

Comparing Two Documents for Plagiarism: Everything You Need to Know

• Posted on April 26, 2024 April 26, 2024

Even though students come to college understanding the consequences of plagiarism, professors still cover the topic, either with a brief lecture or write their plagiarism policy in the syllabus.

This is because plagiarism is tricky, so it is always critical for teachers to restate and clarify what qualifies as plagiarism. Most students can define plagiarism as copying work, or stealing ideas and playing it off as their own. Yet, still, it happens—intentionally or unintentionally.

Often times plagiarism happens accidentally because there is a lack of understanding of the consequences. It most frequently happens with paraphrasing and students’ and writers’ false beliefs that they do not need to cite their sources.

It is the teacher’s role to prevent plagiarism by providing a clear understanding and the consequences. It is also their responsibility to catch plagiarized papers.

Luckily, checking work for plagiarism doesn’t have to be a hassle. Teachers can easily use a free plagiarism checker like Quetext, which scans and compares papers across the World Wide Web.

We know you want your students to flourish into honest, successful individuals, so we will walk you through why and how to compare documents with a similarity checker or a more advanced plagiarism detection software.

Why to Compare Documents

When teachers receive student papers that appear to have duplicate content, concepts, vocabulary, phrasing, and other similarities indicating potential plagiarism, teachers should check for plagiarism by comparing the work with the suspected source.

To compare two texts for plagiarism, teachers can do this manually or with an online checker. To compare two essays for plagiarism manually, the process can be time-consuming. A teacher will suspect a student of plagiarism if their assignments are drastically different than the quality of work that the student typically submits. For example, if the paper appears to drastically exceed the student’s vocabulary level, that’s a fair indication of possible plagiarism.

When using a text comparison tool, teachers must first find the source, then cross-reference it with the student work to find matches in sentence structure, ideas, and style to confirm plagiarism. Many online text-compare websites can examine copied, similar, and paraphrased text by putting two documents against each other to generate comparison results. These websites frequently support text documents with different file formats like plain text, Word documents (docx), text files (txt), PDF files , and websites with HTML.

Comparing documents with an online tool is important when a teacher suspects, but isn’t sure, that two papers contain duplicate content.

How to Check Documents for Plagiarism

It’s important to remember that comparing documents isn’t the same as actually using a plagiarism checker. A text compare tool’s only purpose is to compare two documents for plagiarism by putting them side-by-side with the help of technology. In other words, they aren’t connected to the internet, so they won’t scour the internet for similar publications. Document comparisons simply scan the two pieces, check similarity, and flag similar content.

While both are valuable tools for teachers to check for plagiarism, plagiarism checkers typically make the process of checking simpler and faster. After all, it can be tedious to check for plagiarism with document comparison tools because it requires repetitive uploading or copying and pasting work two at a time. Additionally, if a comparison tool finds similarities, teachers must spend valuable time searching the internet for these articles through a lengthy copy-paste procedure.

Plagiarism checkers, on the other hand, can cross-analyze a student’s work across billions of web pages to find exact matches and similarities. Of course, various online checker tools can check for plagiarism, but QueText’s plagiarism detector goes a step further by offering advanced algorithms and technology. The checker cross-analyzes papers against billions of web pages with state-of-the-art DeepSearch technology, crafted behind over a decade of research, to generate an originality report of exact matches and similarities.

QueText’s plagiarism detector with advanced technology and algorithms makes it a superior plagiarism checker tool for teachers, professionals, and students.

Preventing Student Plagiarism

By providing adequate research and reference resources, and by explaining the consequences involved, teachers can help stop students from succumbing to plagiarism. Other ways to avoid plagiarism from happening are offering guidance with writer’s workshops and emphasizing academic honesty.

In addition, teachers who blatantly inform their students of their plagiarism detection methods typically find lower rates of student plagiarism. By making students aware, they are more likely to check their own work for proper citations before submitting their papers.

Teachers can also encourage students to use a plagiarism checker simply to ensure originality. QueText is a valuable tool for students as it’s free to use, offers citation generation to create citations where needed, and relieves stressors of potential accidental plagiarism.

The citation generator can automatically generate citations for the required writing styles, i.e., APA, MLA, and Chicago. Lastly, even with good intentions, accidental plagiarism happens, and the one way to avoid this is to use an advanced plagiarism checker to ensure it doesn’t happen to you.

Remember, it doesn’t matter if the plagiarized content was accidental, since the consequences remain the same. Accidental plagiarism happens and one way to avoid it is to submit your work through an advanced plagiarism checker.

In college, there’s a zero-tolerance policy for students who plagiarize. So, teachers need to eliminate the possibility of plagiarism early in students’ educational journey, so they don’t suffer the consequences later.

The last thing a teacher wants is for their former student to be kicked out of higher education because they plagiarized. While it’s the student’s responsibility to avoid plagiarism, it’s crucial to ingrain a wholehearted understanding of plagiarism and the consequences early on. For example, students should know that even re-submitting their own previously written work into a new piece without citing themselves can qualify as plagiarism.

QueText offers a teacher’s subscription to its plagiarism checker tool that can help enhance the way you teach your students. While many times teachers can quickly suspect plagiarism, QueText’s checker tool can confirm these suspicions better and faster than manual checking and comparing documents.

Since QueText offers advantages for teachers and students, teachers can ensure their students submit original work by having them run their papers through the plagiarism detector tool before submitting.

Crossmark community consultation: what did we learn.

In the first half of this year we’ve been talking to our community about post-publication changes and Crossmark. When a piece of research is published it isn’t the end of the journey—it is read, reused, and sometimes modified. That’s why we run Crossmark, as a way to provide notifications of important changes to research made after publication. Readers can see if the research they are looking at has updates by clicking the Crossmark logo.

A service provided by Crossref and powered by iThenticate—Similarity Check provides editors with a user-friendly tool to help detect plagiarism.

Our Similarity Check service helps Crossref members prevent scholarly and professional plagiarism by providing immediate feedback regarding a manuscript’s similarity to other published academic and general web content, through reduced-rate access to the iThenticate text comparison software from Turnitin.

Only Similarity Check members benefit from this tailored iThenticate experience that includes read-only access to the full text of articles in the Similarity Check database for comparison purposes, discounted checking fees, and unlimited user accounts per organization.

With editors under increased pressure to assess higher volumes of manuscript submissions each year, it’s important to find a fast, cost-effective solution that can be embedded into your publishing workflows. Similarity Check allows editors to upload a paper, and instantly produces a report highlighting potential matches and indicating if and how the paper overlaps with other work. This report enables editors to assess the originality of the work before they publish it, providing confidence for publishers and authors, and evidence of trust for readers. And as the iThenticate database contains over 78 million full-text scholarly content items, editors can be confident that Similarity Check will provide a comprehensive and reliable addition to their workflow.

Making sure only original research is published provides:

• peace of mind for publishers and authors that their content is identified and protected,
• a way for editors to educate their authors and ensure the reputation of their publication, and
• clarity for readers around who produced the work.

Benefits of Similarity Check

Similarity Check participants enjoy use of iThenticate at reduced cost because they contribute their own published content into Turnitin’s database of full-text literature. This means that as the number of participants grows, so too does the size of the database powering the service. More content in the database means greater peace of mind for editors looking to determine a manuscript’s originality.

If you participate in Similarity Check, not only do you get reduced rate access to iThenticate, but you also have the peace of mind of knowing that any similarity between your published content and manuscripts checked by other publishers will be flagged as a potential issue too.

As a Similarity Check user, you also see extra features in iThenticate, such as enhanced text-matches within the Document Viewer.

How the Similarity Check service works

To participate in Similarity Check, you need to be a member. Similarity Check subscribers allow Turnitin to index their full catalogue of current and archival published content into the iThenticate database. This means that the service is only available to members who are actively publishing DOI-assigned content and including in their metadata full-text URLs specifically for Similarity Check.

Turnitin indexes members’ content directly via its Content Intake System (CIS). Its CIS accesses our metadata daily to collect the full-text content links provided by our members within their metadata. Turnitin follows these URLs and indexes the content found at each location.

When you apply for the Similarity Check service, Turnitin will check that they can access your existing content via the full-text URLs in your Crossref metadata. Once confirmed, you’ll be provided with access to the iThenticate tool where you will be able to submit manuscripts to compare against the corpus of published academic and general web content in Turnitin’s database. You can do this in the iThenticate tool, or through your manuscript submission system using an API. iThenticate provides a Similarity Report containing a Similarity Score and a highlighted set of matches to similar text. Editors can then further review matches in order to make their own decision regarding a manuscript’s originality.

Download the Similarity Check factsheet , and explore factsheets for other Crossref services and in different languages .

Fees for Similarity Check

Similarity Check fees are in two parts: an annual service fee, and a per-document checking fee.

The annual service fee is 20% of your Crossref annual membership fee and is included in the renewal invoices you receive each January. When you first join Similarity Check, you’ll receive a prorated invoice for the remainder of that calendar year.

Per-document checking fees are also paid annually in January. Volume discounts apply, and your first 100 documents are free of charge.
