Proof-of-Decision · Live demo
Most systems show you the output.
We show you what actually happened.
Below: an AI output, a signed receipt, and a status badge.
Click Tamper With Output. Change one character. Watch the signature break.
"All this has happened before — but together, it doesn't have to happen again."
Why this matters
The hash above is computed live in your browser via the Web Crypto API. Nothing was sent to a server. If a third party gave you this exact text and the expected hash, you could check it yourself, offline, with one line of JavaScript.
That's the entire idea behind SONATE: every AI interaction can produce a signed receipt that anyone — regulator, auditor, counterparty — can independently verify. No vendor trust required.

Full SONATE demo
The complete governance flow — policy, drift, alerts, receipts.
This demo is intentionally small and visible. The production protocol adds Ed25519 signing, RFC 8785 canonicalization, hash chaining, and policy decision metadata. The principle is the same: anyone can verify.
