Can your AI prove what it actually did?

Most AI products can show you what they generated.

But can they prove:

  • which prompt was received,

  • which model produced the response,

  • which policy evaluated it,

  • what verdict was returned,

  • and whether the record was changed later?

We built SONATE around the idea that AI accountability needs more than logs and dashboards. It needs independently verifiable evidence.

SONATE by YSEEKU - Cryptographic receipts that prove what your AI actually did.

SONATE creates cryptographically signed Trust Receipts for AI interactions. Each receipt binds the prompt, response, model metadata, policy outcome, and governance context into tamper-evident evidence anyone can verify. Unlike ordinary logs, receipts are portable, independently checkable, and fail verification if altered. Generate a response. Govern it. Break the receipt. Verify it yourself.
