What is Scribbr?

Scribbr is an academic writing platform for students and researchers, combining a plagiarism checker licensed from Turnitin, professional human proofreading and editing, AI proofreading, an AI detector and a free citation generator covering APA, MLA, Chicago and other styles. The plagiarism database spans tens of billions of web pages and millions of publications across 20 languages, and uploaded documents are not added to a content database. The pricing model is the thing to understand. There is no subscription: checks are billed per document, roughly $19.95 for short papers up to about 7,500 words, $29.95 for medium and $39.95 for long ones, so revising and rechecking a thesis several times gets expensive. One technical caveat matters academically: Scribbr checks against Turnitin's web and publication database, not the student paper repository your university sees, so results can differ from your institution's report.
