Everything runs on your device, so cost doesn't scale with how much you use it. That's why Smart Chart and Seating Pro are one-time unlocks instead of a monthly plan.
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.
Everything runs locally — generating one chart or a thousand costs us the same, so Smart Chart and Seating Pro are one-time unlocks, never a subscription.

Yes. Pasting a roster, choosing a layout, shuffling, manually rearranging, printing, and even the rule solver are free with no limits and no account. Paying unlocks applying the solved plan to your chart, alternative layouts, and export extras like name cards.
No. Everything — names, layout, rules — stays in your browser tab. Nothing is sent to a server, logged, or stored, whether you're using the free tool or Seating Pro.
Yes — switch "Arranging" from Desks to Tables and set how many tables and seats per table. Rules adapt too: "keep apart" and "keep together" mean different/same table, and you can seat the wedding party at the head table.
Yes — click one seat, then click another, and the two swap. No dragging required, so it works the same on a phone as on a laptop.
The free rule solver already tells you whether a valid arrangement exists for your rules. Paying lets you apply that arrangement to your chart, see 5 alternative layouts, export a clean PDF or printable name cards, and save the project so you can reopen it later.
Both are one-time purchases that never expire — neither is a subscription. Smart Chart ($7.99) unlocks one saved project: solve it, apply the plan, export it, and reopen it as many times as you like, forever. Seating Pro ($39) removes that cap — unlimited saved projects, plus CSV import. If you're managing more than about five classes or events, Seating Pro works out cheaper than buying Smart Chart for each one.
