Random Group Generator

Split a class list into groups with rules. Your list never leaves this browser.

Names and groups

Add ", M" or ", F" to balance gender. Add ★ to spread leaders.

Groups

    Conditions:

    Everyone on a line goes to a different group.

    Print:

    Uses your printer's paper size (A4 or Letter).

    History, sharing, backup

    Past groups (newest first, up to 10)

      Without names, people appear as list numbers (1, 2, 3…).

      Your list, conditions, and history are stored only in this browser (localStorage, key toban_group) and are never sent anywhere.

      How the groups are made

      Groups are as even as possible: sizes differ by one person at most. With rules on, the tool shuffles and swaps people to meet every rule. If a rule cannot be met, it tells you which one.

      The same draw number, list, and settings always give the same groups, so a shared link shows exactly what you saw.
