Frequently asked questions
Is my text sent anywhere?
No. The comparison runs in your browser, which is what makes the tool safe for contracts, source code and anything else confidential.
What do the colours mean?
Added parts are marked as additions, deleted parts as removals, and everything else is shown as unchanged so you can see the context around each edit.
Can I compare code?
Yes. Indentation and line breaks are preserved, so shifted blocks and whitespace-only edits still show up as differences.
