Plagiarism Checker

Our Plagiarism Checker extracts key sentences from your text and searches the web for matching content. It compares your text against online sources to identify potential duplicates and provides links to the original sources.

This tool provides a good indication of potential plagiarism by searching public web content. However, it may not catch all instances, especially from paywalled or private content. For academic or professional use, consider using it alongside other plagiarism detection tools.

Yes! Our Plagiarism Checker is completely free with no API keys or sign-ups required. Simply paste your text to check for potential plagiarism instantly.

You can check texts of any length, but the tool analyzes up to 5 key sentences at a time to ensure accurate results and avoid rate limiting. For longer documents, you may want to check sections separately.

The originality score shows the percentage of checked sentences that appear to be unique. A higher score means more original content. Note that common phrases or quotes may trigger matches even in original work.
