About Scribbr
Scribbr is an academic writing helper built for students. It started with human proofreading and editing of theses and essays, and now offers a set of web tools around it: a plagiarism checker that uses the same kind of database universities rely on, an AI detector, a grammar checker, a paraphraser, a summariser, an AI proofreader and a citation generator for APA, MLA, Chicago and other styles. The plagiarism checker is unusual in charging per document rather than by subscription: a free check gives a risk overview, and a premium report shows the exact similarity percentage, highlighted matches, side-by-side comparisons and a self-plagiarism check against your own earlier work. Many of the smaller tools are free with limits, and the human editing service is priced per word and deadline. It is web-only and geared towards academic papers in English and a few European languages, rather than business or marketing writing.
Best for: Students checking a thesis or essay for plagiarism, citations and errors before submission.
