About Scribbr Plagiarism Checker

What We Do

Scribbr Plagiarism Checker is an independent online tool that helps students, researchers, and academic writers verify their work for unintentional plagiarism before submission. We scan submitted text against a comprehensive academic database covering billions of web pages and tens of millions of published academic papers, then return a similarity score along with a detailed source-by-source breakdown.

Our goal is simple: give students access to the same level of plagiarism checking their institutions use, at a price that makes sense for an individual rather than an institution.

Who We Are For

We built this tool for students who want to submit with confidence. The most common scenario: you finish a paper, you know you have cited your sources, but you want to verify that nothing has been missed before your instructor runs it through their institutional checker. That is exactly what this tool is designed for.

• Undergraduate students writing research papers and essays
• Graduate students preparing theses and dissertations
• PhD candidates running pre-submission checks on journal articles
• Teaching assistants who want to check their own written work

How the Checker Works

When you paste or upload your document, our system scans the text against a multi-source academic database that includes published journal articles, institutional repositories, and indexed web pages. The system returns a similarity percentage and, on paid plans, a detailed report showing every matched source, the specific passages that triggered each match, and citation format recommendations for each flagged section.

Independence and Accuracy

Scribbr Plagiarism Checker is an independent tool. We are not affiliated with any university, learning management system, or institutional software vendor. Our similarity scores are intended as a reliable pre-submission reference — not as a formal academic integrity decision.

Results should be interpreted alongside the citation and attribution context of your document. A similarity score is a starting point for review, not a verdict.
