What is Scribbr?

Scribbr is an online plagiarism checker built primarily for students and academic writers, powered by Turnitin's detection engine. It compares submitted text against a wide range of sources, including open and restricted access journals, theses, dissertations, websites, PDFs, and news articles, then returns a similarity score with linked, highlighted matches. Advanced algorithms catch not just exact copying but paraphrasing and synonym swapping, and the tool can flag content that appears to be AI generated.

Rather than a subscription, Scribbr sells single checks priced by document length, plus custom volume pricing for institutions. A unique self plagiarism feature lets writers upload their own unpublished work to compare against. Premium checks also unlock an integrated grammar checker, and submissions are never added to any public database.
