FAQ
Does it compare text or appearance?
Visual comparison — it catches text edits, layout shifts, and image changes alike.
Is it safe for confidential documents?
Yes. Processing happens locally in your browser (client-side). You can even disconnect from the internet after the page loads and most tools keep working.
