Turn scattered event notes into a minute-by-minute day-of timeline — a vendor contact sheet, then setup, pre-event, program, and teardown with a time and a responsible party on every line, buffers between transitions, vendor meals slotted in, the venue curfew called out, and a contingency plan. No blank page, no rebuilding the run-of-show from last season's spreadsheet. Two ways to run it: • On a paid Claude plan? Install the free Event Planner plugin and type /event-timeline. One command, done. • Any other AI — free Claude, ChatGPT, Gemini? Copy the built-in prompt (a sample day-of timeline is prefilled), paste it in, swap your details. Inside: the full prompt with a sample day-of timeline, the one-command Claude path, built-in accuracy rails, and a two-minute setup walkthrough. Opens in your browser. AI writes a fresh day-of timeline every time — read it before it goes out. The rails keep it on track, not replace your review. Want the whole event-planning workflow — client proposals, vendor outreach, client updates? The full Event Planner pack doesn't exist yet — you're early. Join the free waitlist and your requests shape what gets built.
