The vault and trust layer for AI agents.

Move over the glass.

The AI got the result — never your password.
  1. 1You ask your AI.
  2. 2The AI asks Tansu. It never gets the key.
  3. 3Tansu opens the drawer in a sealed room and hands back only the result.
The obvious question

If it’s all sealed, how can an AI use it?

It doesn’t. It never touches the key — it just asks Tansu to do the job. Flip the switch to see the difference.

  • Your password never leaves the vault.
  • Each permit covers one task and expires.
  • The AI only ever gets the result.

Not even we can open it. If we were ever forced to hand over what we hold, all we could give is sealed data we have no key for. How that works
