Consumer Usability
ZeroClash handles large schools with ease. From dragging and dropping schedule blocks to downloading a polished PDF, every step is fast and simple to use.
Drag & Drop Conflict Engine
Manually adjust schedules by dragging blocks. The system validates constraints in real-time, completely preventing double-booking.
Instant PDF/Excel Export

Scales to 100+ Teachers
Big school? No problem. Our engine checks millions of options per second to find the best schedule for every teacher and class.

Why schools pick ZeroClash
Real product features that save your coordinator days of manual work every term.
Full school timetable in under 30 seconds

Drag-and-drop any slot, conflicts blocked automatically
Move a Math period to Thursday P2 — the system instantly prevents double-booking the teacher or the class.
Magic AI Fix — one click auto-resolves every conflict
When the first pass leaves gaps, Magic Fix reshuffles the grid to clear them. You approve the final result.
Pin the slots that must not move
Lock the Principal's assembly, a fixed lab period, or a senior teacher's off-day — the engine builds around your pins.
Bulk upload via Excel — no tedious forms
Paste 80 teachers and 200 workload rows from a spreadsheet. Templates provided, errors flagged row-by-row.
Separate Primary and Secondary wings in one school
