Text diff tool

Use this text diff tool to compare two blocks of text line by line and see additions, removals, and unchanged lines. It is useful for comparing configuration files, logs, JSON snippets, documentation drafts, and copied command output.

Diffing runs locally in your browser, so both text inputs stay on your device.
