described a rough workflow in plain English ("route billing questions to billing help, escalate only when the caller explicitly asks for a human") and it generated actual states and transitions from that, no signup or account needed, everything saved locally in the browser. ran the simulation mode (no API key required) with a test message and it correctly matched the right end state with a confidence score and a transition-probability breakdown, which is more transparency than i expected from a free tool. the fact that regression tests and runnable TypeScript export sit right next to the simulator, instead of behind a separate paid tier, is the part that'd make me actually use this instead of just admiring it
