Every AI decision.
Cryptographically verified.

The problem

AI output travels without proof of origin

Once a response leaves the chat window, it can be copied, edited, or misattributed with nothing to show what model produced it, when, or whether it still says what it originally said.

The fix

A signed passport travels with it

VeriAI hashes the prompt and response, signs them with an Ed25519 key, and gives you a shareable link anyone can use to confirm the content is authentic and unmodified.

Three steps, in order

01

Generate

Paste the AI provider, model, prompt, response, and a confidence score into the passport form.

02

Sign

VeriAI hashes both fields with SHA-256 and signs the record with an Ed25519 private key held server-side.

03

Verify

Share the verification link. Anyone can recompute the hashes and check the signature — no account needed.
