Diff Checker
Paste an original and a changed version to see exactly what's different.
How does the diff checker work?
Paste the original text on the left and the changed version on the right, then hit Compare. Lime Kit's Diff Checker lines up both versions and highlights every line: green for lines added, red for lines removed, and plain for lines that are unchanged — the same line-based comparison used by code review tools and version control diffs.
Useful for comparing drafts, config files, or any two blocks of text. Everything runs locally in your browser; neither version is ever sent anywhere.
