Frequently Asked Questions

Does this tool check plagiarism on the internet?

No. This tool performs text-to-text similarity analysis between the two texts you paste. It does not search the internet, academic databases, or any external source. It is designed for comparing two specific texts — like checking rewritten content against the original, or comparing two documents.

What algorithms are used?

Two genuine algorithms are used: Jaccard similarity (measures overlap between unique word sets) and Cosine similarity (measures the angle between word frequency vectors). The overall score is the average of both.

What does 100% similarity mean?

If both texts are exactly identical (word-for-word), the similarity score will be 100%. If both texts share all the same words but in different order, the Jaccard score remains 100% but Cosine may vary.

Are my texts stored anywhere?

No. All processing happens in your browser. Your texts are never sent to any server, and nothing is stored.
