About the Plagiarism Checker

This tool scans your text against publicly available online content to help identify passages that closely match existing published material, useful for writers and students verifying originality.

How It Works

Your text is broken into segments and compared against indexed web content; matches above a similarity threshold are flagged for your review alongside the likely matching source.

Why Use This Tool

Frequently Asked Questions

Does a plagiarism check guarantee 100% originality?

No automated tool can check against every piece of content ever published; results should be treated as a helpful screening step rather than an absolute guarantee.

Will properly cited quotes be flagged as plagiarism?

Direct quotes will often be flagged as matches since they intentionally repeat other text; proper citation practice is still the responsibility of the writer, separate from the raw similarity match.

Is my submitted text stored or shared after checking?

Text is processed for the purpose of the similarity check and is not intended to be published or shared elsewhere.
