Compare two texts and highlight differences line by line
Built & maintained by Pappu Venkata Subbi Reddy, founder of Clacify
Clacify's Text Diff Checker compares two blocks of text and highlights additions (green), deletions (red), and unchanged lines side-by-side or inline. Useful for comparing document versions, spotting changes between contracts or agreements, verifying code changes, finding differences between two JSON responses, or checking if translated text matches the original structure.
Paste the first text in the left panel and the second text in the right panel of Clacify's Text Diff Checker. The tool instantly highlights additions in green, deletions in red, and shows unchanged lines in grey. This makes it easy to spot exactly what changed between two versions.
A text diff shows line-by-line differences between two texts. Lines marked + (green) appear only in the second text (added). Lines marked - (red) appear only in the first text (removed). Unchanged lines are shown without marking. This is the same format used by Git to show code changes.
