| Approval model | Auto Review evaluates tool calls and computer actions before they run, with user rules set to Ask first or Allow automatically; Ask first wins when both match. Before actions it cannot undo, such as sending, posting, buying or deleting, a Bot checks for approval; emails go out from draft cards and purchases show an Allow or Deny card. Running commands on the user's own computer defaults to Ask every time. | The homepage says it checks in with the user before doing something that requires approval; action buttons let the user approve tasks such as paying a bill with a tap, and the launch post says it can handle some tasks on its own if the user allows it. |
