Text Diff Checker

See exactly what changed between two texts

Paste an original and a modified version of any text and get a precise, color-coded diff: additions in green, removals struck through in red, and word-level highlighting inside lines that were edited rather than fully replaced. Built on a genuine longest-common-subsequence algorithm, the same core approach behind tools like diff, so unchanged content stays untouched instead of flashing as "everything is different."
