The idea

Teachers fill in their class schedule, routines, seating notes and emergency procedures once. When they need a sub, they add the day's activities and get a clean, printable plan and a share link. It removes the late night scramble when a teacher is sick.

Your first AI prompts

Paste these into Claude, Cursor or Lovable, in order. Check that each one works before moving on.

PROMPT 1 OF 3

Build a web app called Sub Plan Pack. Teachers sign up and complete a profile binder with sections: bell schedule, class periods, daily routines, helpful staff contacts, emergency procedures and classroom rules. Each section is a simple rich text form.

PROMPT 2 OF 3

Add a New Sub Day flow: pick a date, and for each period enter the activity, materials location and what to collect. Offer an AI button that turns short notes like "ch 4 worksheet, quiet reading" into clear step by step instructions a stranger can follow.
