What’s the difference between side-by-side and inline diff?

Side-by-side shows original and changed text in two columns. Inline shows a single merged view with additions and deletions marked inline.

How do I ignore whitespace or case changes?

Enable the toggles for ‘Ignore whitespace’ and ‘Ignore case’. The diff will recalculate and hide insignificant differences.

Can I export a unified diff or patch file?

Yes. Use Export to download a standard Unified Diff (.patch) or export changes as CSV/JSON for reporting.

Is my content uploaded anywhere?

No. Comparisons run locally in your browser. Nothing is sent to a server unless you export to a file on your device.
