FAQ

Frequently asked questions

How does the tool detect plagiarized or duplicate content?

The checker analyzes your text against itself, identifying repeated sentences, phrases, and exact matches. It highlights duplication within your document but doesn't check against web-wide sources—for that, use dedicated plagiarism services.

Will this checker identify paraphrased plagiarism?

This tool detects exact matches and very similar text. Heavily paraphrased content may not be caught. For comprehensive plagiarism detection including paraphrasing, use Turnitin, Copyscape, or similar platforms that check web sources.

Is the plagiarism check fast enough for large documents?

Yes, the tool processes large documents quickly using browser-based analysis. However, browser performance depends on your device. For extremely large files (50,000+ words), check in sections.

Can I check for plagiarism against multiple documents?

Compare two documents by pasting one into the tool and checking it against another. For bulk plagiarism checking across many documents, use dedicated platforms with batch upload capabilities.
