Questions

Is this a visual diff or a text diff?

Both. Text differences are shown clause by clause, and a visual overlay highlights layout and image changes that a text diff would miss.

Can it summarise what changed?

Yes, with AI enabled you get a plain-language summary alongside the diff — and it cites the pages, like every other answer.

Security note

Files are checked to be what they claim (by content, not extension), processed in a sandboxed worker with no network, and deleted on the schedule your plan sets. We do not run antivirus and do not claim to — please do not upload files you do not trust. Read the security page.
