Frequently Asked Questions

What does the diff tool show?

Lines that appear only in the original text are shown in red (deleted). Lines only in the new text are shown in green (added). Unchanged lines appear in grey.

Can I compare entire documents?

Yes. Paste entire document contents — there is no character limit. Large texts may take a moment to process.

Does it compare at the word or character level?

The tool shows both line-level and character-level differences. Within modified lines, the specific characters that changed are highlighted.

Can I compare code files with this tool?

Yes. The diff tool works for any plain text including code, configuration files, JSON, CSV, and prose documents.
