Text Diff 🔒 Your data never leaves your browser.
Compare two texts line by line — see exactly what changed.
About this tool
This diff compares two texts line by line using the same longest-common-subsequence approach as git: unchanged lines stay plain, removed lines show in red, added lines in green. Perfect for spotting what changed between two configs, SQL dumps, API responses or document drafts.
Comparison happens entirely in your browser — both texts stay on your machine, so it's safe for anything confidential.
