Drop a KAMX certificate and this page recomputes its evidence chain in your browser — no server, no network, no KAMX. It reports whether every link matches, and checks the signature if a signed declaration is included.

Nothing is uploaded. Verification runs entirely on your machine.
Intact means every record hashes to its stated value and links to the one before it — the record hasn't been altered since it was written. It is not a claim that no AI was used, nor a verdict on the footage.
An anchor proves the chain existed no later than its Bitcoin block — an upper bound on time, never a lower one. Confirm the anchor with ots verify beside the certificate.
Attested ≠ verified. A valid signature proves the same key-holder signed these claims over this chain — not who they are.
Only hashes ever leave a machine. This check needs no network and will still work if KAMX no longer exists.
