Text Diff / Compare
Compare two versions of anything — a document, a config file, a chunk of code — and instantly see what changed. The comparison uses a longest-common-subsequence diff, the same approach behind git diff.
How to use it
- Paste the original text on the left and the changed text on the right.
- Toggle Ignore whitespace and Ignore case if leading spaces or capitalization shouldn't count as changes.
- Read the result: added lines are highlighted green with a
+, removed lines red with a−, and unchanged lines stay neutral. The header shows the total added and removed counts, or an "Identical" badge when the two match.
