FAQ
Does Diff Viewer send my text anywhere?
No. The comparison runs locally in your browser, and the pasted text is not sent to a Monkeybase server.
What kind of changes does it compare?
It is best for text, copy, notes, config snippets, and structured payloads where you need a quick before-and-after review.
Should I format JSON before comparing it?
Yes. Formatting both versions first makes structural changes easier to spot and reduces noise from whitespace differences.
