How it works
This tool computes the Levenshtein edit distance between the two strings and divides by the length of the longer string to produce a similarity percentage. A score of 100% means identical strings; 0% means completely different. Processing runs in your browser.
Common use cases
- Measure how similar two strings are for fuzzy deduplication
- Compare expected and actual values in test output for approximate matching
- Score string proximity for spell-check or autocomplete ranking
