Paste your roster, tell it who needs space, and it works out the desks for you — catching conflicts you'd otherwise miss. Nothing about your class ever leaves your device.
🔒 No login. No student data uploaded, ever.
Minutes, not a Sunday evening
Paste a roster and get a workable chart right away — no more shuffling desks by hand or juggling index cards.
Catches conflicts before they start
Tell it who needs to sit apart or together, and the solver finds an arrangement that respects every rule — or tells you straight away if one's impossible.
Nothing about your roster is uploaded
It runs entirely in your browser. No account, no server, no data collection — your class or guest list never leaves your device.
Not just classrooms
Desks or tables, rows or round tables — it works the same for a classroom, a wedding, or a conference banquet.
Click a seat, then click another to swap them.
Saved charts — local to this device
Save and reopen classes/events next time you visit — Teacher Pro.
Add a rule below — e.g. keep two people apart, or seat someone at the front.
Everything runs locally — generating one chart or a thousand costs us the same, so Smart Chart and Teacher Pro are one-time unlocks, never a subscription.
