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 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.
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 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.
The Scribbr Plagiarism Checker takes about 10 minutes to finish.
For documents larger than 25.000 words it can take a bit longer. You will be shown an estimate at the order overview.
As soon as the check has finished we will also send you an e-mail.

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.
