Verify a receipt

Verify Alvo's sovereignty receipt yourself.

Every Alvo AI brief, email and export carries a zero-egress receipt (EU AI Act, Article 50). Paste one and recompute the attestation right here — no involvement from us.

How it works

  1. 1Copy the receipt (JSON) from the footer of an email/export or the brief card.
  2. 2Optionally add the declared inputs the hash was bound to — to confirm the receipt is tied to exactly those.
  3. 3Click Verify — the page recomputes the hash and checks the claim set (deterministic, no external model, zero tokens, zero data egress).

This is a recomputable attestation, not a cryptographic signature. There is no secret key or PKI — anyone can run the same deterministic recomputation and get the same result. That is the point: trust from reproducibility, not from our word.

The /api/ai/receipt/verify endpoint is public and unauthenticated — which is exactly why a receipt can be verified independently. Nothing you paste is stored.
