My receipts

Receipts you sealed in this browser. They stay on this device; links and downloaded files work anywhere.

What a receipt proves — and what it does not

Proves

The question, answer, model, time and note are exactly what was sealed. Any edit — even one character — is detected and named.
Every receipt with the same signer fingerprint was sealed by the same browser key.

Does not prove

That an AI really wrote the answer. SaidSo seals what you paste; only the AI provider could sign its own output.
The time. It is signed, but it comes from the sealer's clock.
Who the signer is. Compare the fingerprint with one the person shared with you.
