In WhatChanged: The open-source whatchanged skill: code finds every changed clause, so none can be skipped, and four checks verify the explanation.
What changed in what you agreed to?
Drop a link to any terms, privacy policy or contract page and pick how far back to look, or paste two versions. Every changed clause is found, and each one that matters is explained with the exact words before and after.

Questions
How do you find the changes?
Code compares the two versions sentence by sentence, so no change can be skipped. Then AI explains each one in plain words, or lists it as minor with a reason (a new date, menu text). Every quote is checked word for word against both versions.
Where does the old version come from?
From the Internet Archive’s Wayback Machine: the last copy it saved before the date you pick. You can open that copy from the result. If it has none, paste the old version yourself.
Is this legal advice?
No. It shows what changed and what it means in plain words. For a decision that matters, read the clause itself, or ask a lawyer.
Is what I paste stored?
Pasted versions are kept only inside your result, which only someone with its link can open. Link checks are shared: the same link and period checked today shows the same result to everyone.
Can I have a page watched every week?
Yes: press “Watch this page” on a result. Requests are reviewed and added to the open-source monitor, which publishes every change it finds.
Can I build something like this?
Yes. The whatchanged skill, its tests and the monitor are open source on GitHub, and the page runs on Bref UI.
