# Text Similarity Checker

> Compare two texts with Levenshtein distance, Jaccard, cosine and Dice coefficients.

Text similarity can be measured several ways, and they disagree usefully. Levenshtein counts character edits, Jaccard and Dice compare shared vocabulary, and cosine compares word-frequency vectors while ignoring length. This tool reports all four so you can see whether two texts are reworded, reordered or genuinely different.

## FAQ

### Which measure should I trust?

It depends what you mean by similar. Levenshtein catches typos and small edits; cosine spots the same content reordered; Jaccard is best for checking whether two documents cover the same topic regardless of phrasing.

### Is this a plagiarism checker?

No. It compares two texts you supply against each other. Plagiarism detection requires searching a corpus of billions of documents, which no browser tool can do.
