Will Scribbr give the same result as my university’s plagiarism checker?
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).
Luckily, many papers, theses, and dissertations are also published in public databases that Scribbr does have access to.
