About Text Diff
A diff (short for difference) highlights the exact changes between two versions of text. Lines present only in the original are shown in red, lines only in the modified version in green, and matching lines in gray. This is the same concept used by Git, code review tools, and version control systems.
Use Cases
Compare code changes, contract revisions, configuration files, translated texts, or any two pieces of text. The entire comparison runs locally in your browser — nothing is uploaded.
