Build the wedding seating chart in one screen. Add guests, build tables (round or rectangular, with per-table capacity), and assign each guest to a table via a dropdown. Plus-ones and kids are counted so a 'John + guest + 2 kids' row takes four seats. Capacity warnings light up red the moment a table is over. Move a seated guest to a different table any time. Print to PDF for a clean floor-plan one-pager the caterer and venue can lay out from. Everything is stored locally in your browser — no account, no upload, no sync.
