Type the times and the tasks, print the run sheet, hand it to the crew. Free, no signup. Or run the event from a group chat with an AI keeping time.
The same chart lives in a free group chat with an AI member: it reminds each person, tracks streaks, and checks itself off from any phone. No signup to try it.
See it run in a RoomA minute-by-minute plan for event day: what happens, when, and who owns it. One page, big type, taped backstage.
Everyone with a job. The Room version sends each person their own list and checks items off live as they finish.
Every moment that involves a handoff gets a line. If two people must coordinate, it is on the sheet.
