Text Change Counter

Measure edit counts and similarity locally with selectable line, word, or grapheme granularity.

Granularity

Comparison runs locally in your browser. Interactive diff uses a bounded token count to avoid locking the page on extremely large inputs.

Change counts distinguish replacement groups from raw insert/delete tokens

A replacement is still represented by delete+insert operations, but contiguous mixed edit regions are also reported as replacement groups to make the edit summary easier to interpret.
