AI is already in your product. Bills climb, bots get tricked, agents act unchecked. We fix all three.

Each figure comes from one of our public demos: fictional companies, real model runs.

    The agent proves who it is and what it may touch.

  2. 02 Schema

    Every argument is checked against the tool’s contract.

  3. 03 Policy + risk

    Your rules and a risk score. $1,800 is over the $1,000 limit.

  4. 04 Service

    Billing waits for a person to approve the $1,800 refund.
