Text Diff

The Text Diff tool compares two pieces of text and highlights exactly what changed, line by line — additions in one color, deletions in another. It's the fastest way to spot differences between two versions of a document, config file, contract clause or code snippet without reading both end to end.

Paste the original text on one side and the modified version on the other; the diff renders instantly. Unlike command-line diff tools, there's nothing to install and the side-by-side layout makes changes obvious at a glance.

Comparison runs locally in your browser, so it's safe for private documents and proprietary code.
