Industry-leading plagiarism software
We developed the Scribbr Plagiarism Checker in partnership with Turnitin.
In addition to 70 billion current and historic web pages, we have unique access to more than 69 million scholarly publications and books.
The Scribbr Plagiarism Checker, in partnership with Turnitin, uses a sophisticated algorithm to detect not only exact matches but also paraphrased text.
In contrast to other plagiarism checkers, we don’t store or sell your work. You can delete your document anytime. It’s hassle-free!
The Scribbr Plagiarism Checker has been named the best plagiarism checker of 2019.
It detects more plagiarism than any other plagiarism check and is highly accurate. Compared to other plagiarism checkers, the report contains fewer false positives, which saves students time.
Your plagiarism report contains three main elements: a similarity percentage, a list with matched sources and a preview that highlights matched text in your document.
Whereas many other plagiarism checkers can only detect exact matches, the Scribbr Plagiarism Checker also detects patchwork plagiarism.
In other words, our software can detect plagiarism even when you paraphrase sentences or combine multiple sources.
The similarity percentage indicates what portion of your text matches other sources in our database.
The plagiarism software excludes your reference list and other sections where similarities are common but are not actually plagiarism.
Therefore, the similarity percentage is highly accurate.
All sources containing text that is similar to yours are listed and sorted according to significance.
This list helps you easily identify the original source and cite it accordingly. You will even receive a preview of the original passage, so you can easily compare it to your own text.
When you find plagiarism in your document, it is important to cite the source correctly. Our Plagiarism Knowledge Base helps you understand and correct plagiarism.

The Scribbr 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.
No, the Scribbr Plagiarism Check does not result in your document being published in any public database (unlike many other free plagiarism checker services).
As soon as you’ve received the result from the Plagiarism Checker, you can directly delete all details and documents from the Scribbr server.
The Scribbr Plagiarism Checker, in partnership with Turnitin, compares your document against the largest and fastest-growing content database in the world:
The Scribbr Plagiarism Checker does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.
In your plagiarism report you can see the database in which the original source is found.
The Scribbr Plagiarism Checker compares your document against the largest plagiarism database in the world. It will detect any similarities with documents in that database.
However, you might be unsure if all of the sources you used are in that database – for example, because some of your sources are unpublished. In this case, you can make use of our Own Sources Checker. Here you can add all the sources you want to a private database and compare them with your own document.
The Scribbr Plagiarism Checker needs approximately 10 minutes to process your document. This time is needed to compare your paper with a massive database with billions of web pages and publications. Documents larger than 35.000 words can take a bit longer.
We will send you an e-mail when the check is finished!
The Scribbr Plagiarism Checker will only check your document for plagiarism once. Don’t worry – if you have followed our guide, as well as our articles on preventing plagiarism and citing sources, there is no need to perform a second plagiarism check.
Keep in mind that if you try to avoid plagiarism by paraphrasing, you still need to include a reference to the original source.
If you still want to perform a second plagiarism check, you’ll have to buy a new check at the regular price.
We understand this concern. However, since the Scribbr Plagiarism Checker does not store any documents that it checks in a shared database, it’s impossible for this to happen.
As an added precaution, you can also personally delete your details and documents from Scribbr’s own server as soon as you’ve received the results of your Plagiarism Check.
The Scribbr Plagiarism Checker is optimized for students, which means that you will receive a detailed report with extra information to fix and avoid plagiarism, similar to the report received by your school.
Universities often have their own database of (prior) theses. Scribbr has no access to those databases. When you copy data from another thesis that is not publicly accessible, the Scribbr Plagiarism Checker will neither be able to detect plagiarism nor identify the source of this data.
However, most papers are actually publicly accessible since many universities and schools have public databases. This means that the Scribbr Plagiarism Checker is able to find these papers.
