Verify a receipt
Paste or upload a TSP receipt and its issuer public key. The Ed25519 + SHA-256 cryptography is re-run here, in your browser, against that key — nothing trusts the issuer. Change a single byte and it fails.

verification result
Paste a receipt and verify — or load a sample.
Available after a verify run. The record captures what this browser computed — verified or failed — with the bundle, so anyone can recompute it.
What verification does not mean
- that the AI's answer is true or correct
- that you are legally compliant
- that the model is approved or safe
- that the issuer holds official status — that needs authorization
Safe to choose — because you can leave. Verification stays free, open and offline, with no account and no dependency on us: your receipts verify either way.
