Compare Text - Find Differences per khaja hussain

Compare two blocks of text and see exactly what changed, right in your browser.

Paste your original text on the left, the changed version on the right, and the differences light up instantly. Removed text shows in red, added text in green, down to the character.

What you can do:
- Two-pane live diff with inline red/green highlights
- A per-pane counter so you know how many changes there are
- Load a sample, upload a file, copy, download, clear, or swap the two sides
- Options for wrap lines, ignore case, and ignore whitespace
- Right-click selected text on any page and send it straight into the comparer
- "Full view" opens the full web app at comparetext.org

Everything runs locally on your machine. Your text is never uploaded, and the only thing stored is the two panes you're working on, kept in local browser storage so they're still there when you reopen the popup. No account, no sign-up, no tracking.

Good for proofreading drafts, checking config file changes, reviewing contract edits, comparing translations, or spotting what moved between two versions of anything.

Built on Google's diff-match-patch, the same algorithm behind many code-review tools.
