One click puts an invisible cryptographic seal on any AI answer. Anyone, anywhere, can verify it later. Free. Private. Forever.
AI talks to billions of people every day. Sometimes it gives bad medical advice. Sometimes it pushes fraudulent investments. Sometimes it just hallucinates. Until now, that text was just text. Now it can be evidence.
AI suggests a treatment? Seal it. Tomorrow your doctor can see exactly what was said, signed and timestamped.
AI tells you a token is "guaranteed safe"? Seal it. If it turns out to be fraud, you have cryptographic proof.
AI writes legal, tax, or technical opinions for you? Seal them. Nobody can later claim "it never said that".
AI says something obviously wrong or dangerous? Seal it and share it. The world deserves a record.
Three steps. No accounts. No passwords. No data collection.
Use ChatGPT, Claude, Gemini, or Perplexity like normal. Get an answer.
A small blue button appears under each answer. Click it. The text gets an invisible signature woven into it.
Paste the text into WhatsApp, email, Word — the seal travels with it. Anyone can verify it at croviatrust.com/check.
Two ways to get it on your devices.
Crovia Seal is built on @crovia/seal SDK and the IETF draft-crovia-seal-01 specification. Every seal is a JSON receipt signed with Ed25519 over CSC-1 canonicalization. Every signature is verifiable in any browser, in any language, forever.
