School Timetable Builder

School Timetable Builder creates a complete weekly timetable for a primary or lower-secondary school: one timetable per class and one per teacher, including rooms.

Describe your school in the chat, in your own language: classes, subjects and lessons per week, teachers and what they teach, rooms and the school day. ChatGPT interviews you one topic at a time and checks the data with the service in a few seconds, for example whether there are enough qualified teachers and enough time in the week. Then the timetable engine calculates the full timetable, usually in 5-8 minutes. If the rules cannot all be met, you get a plain explanation of why, and you decide what to change.

You get the finished timetable as files in the chat (for example a spreadsheet with one sheet per class and one per teacher), plus a "School data" file so you can run it again later.

What the engine handles: 5 school days a week, 1-12 lessons a day, grades 0-10, double lessons, daily limits per subject, special rooms (such as a sports hall or music room), fixed teachers for a class, classes taught together, and fixed blocked times for teachers or classes. Not supported: student-choice course timetables (high-school style), whole-day events, and wishes or preferences.

Privacy: ChatGPT replaces teacher names with codes (T01, T02, ...) before anything is sent and puts the real names back when the result comes in. The service never receives the names of teachers, pupils or the school, and it deletes all data within 24 hours. No account is needed. Usage has shared hourly and daily limits.
