Industry-leading technology
We partner with Turnitin, the leader in plagiarism prevention software.
Our software only highlights the similarities that are most likely plagiarism. Commonly used words and phrases along with your reference list are ignored.
In partnership with Turnitin, the Scribbr Plagiarism Checker compares your document to over 70 billion web pages and 69 million scholarly publications.
We never add your paper to our database. After the check, you can delete your document right away. Your document stays yours.
Like many other plagiarism checkers, the Scribbr Plagiarism Checker identifies sentences that are exactly the same as in the original source.
However, it also detects plagiarism in paragraphs where the sentence structure is changed, synonyms are used, extra words are inserted or text from multiple sources is combined.
Compared to other well-known plagiarism checkers, the Scribbr Plagiarism Checker is more accurate and detects more plagiarism.
Why? Our database contains not only websites but also books and journal articles. Combine this with the most advanced plagiarism detection technology available, and you have the best plagiarism checker.
Thousands of students have used the Scribbr Plagiarism Checker to detect, understand and correct plagiarism.

The plagiarism percentage indicates what portion of your paper matches other sources in our database.
The percentage is accurate and does not include similarities found in, for instance, your reference list.
The plagiarism report displays a list of all the sources that match your paper and a preview that highlights the similarities.
A similarity can range from a couple words to entire sentences or paragraphs.
The structure of the report allows you to easily find the original source and cite it correctly.

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.
The Scribbr Plagiarism Checker will only check your paper 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.
Almost all languages are supported by the Scribbr Plagiarism Checker. You can find a complete list of the supported languages below:
The Scribbr Plagiarism Checker is optimized for students, which means that you will receive a detailed report with extra information to fix and prevent plagiarism, similar to the report received by your school.
Schools 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 theses are actually publicly accessible since many universities and schools have public databases. This means that the Scribbr Plagiarism Checker is able to find these theses.
We accept the following payment methods:

Transaction fee of 2% – 3,9%.

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.
No, the Scribbr Plagiarism Check does not result in your document being published in any public database (unlike other 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.
