Public proof verifier

Verify a Proof

Drop one credentialed audio file. We’ll confirm its proof, signer, and exact audio binding — free, with no account. Older audio can still be checked with its .poh sidecar.

PoH's credentialed WAV copies carry the proof inside. Other exports verify with the optional .poh sidecar below.

Privacy & file handling

Your audio is uploaded only to check its fingerprint against the proof. It lands in a short-lived store that clears automatically — it isn’t reused or added to anything.
