Will I get a 100% match at my school when I use the Scribbr Plagiarism Check?
We understand this concern. However, since the Scribbr Plagiarism Check does not store any documents that it checks in the shared Ephorus database, it's impossible for this to happen (even if your schools also uses Ephorus software).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.
How long does the Scribbr Plagiarism Check take?
The Scribbr Plagiarism Check takes about 10 minutes to finish. For documents larger than 35.000 words it can take a bit longer. As soon as the check has finished we will send you an e-mail.
Will my document be published on a (public) database?
No, the Scribbr Plagiarism Check does not result in your document being published in any public database (unlike other plagiarism check services).As soon as you’ve received the result from the Plagiarism Check, you can directly delete all details and documents from the Scribbr server.
Will the results be the same as the results of the check used at my school?
The results of the Scribbr Plagiarism Check will be 99% the same as the Ephorus check used at your school. The Scribbr Plagiarism Check  is optimized for students, which means that you will receive a detailed report with extra information to fix and prevent plagiarism.

Minor difference

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 Check 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 Check is able to find these theses.
