# Receipt > Your AI coworker that proves what it did. Receipt runs tasks across your SaaS apps and servers, then backs every result with a verifiable receipt. Receipt runs tasks across your connected SaaS apps and servers in an isolated sandbox, gates state-changing operations behind org policy, and records every step as an immutable, cryptographically chained receipt you can replay and verify independently.
