Why random is the point
Debate teaches you to argue any side. Random assignment removes the temptation to only practise positions you already hold.
Pro vs con, government vs opposition — paste your debaters and split into balanced sides without favourites.

Debate clubs, MUN preps, public-speaking classes. Random sides force participants to argue positions they disagree with — half the educational value of debate.

Set people-per-team to 2 and let the tool generate four teams (Opening Gov, Opening Opp, Closing Gov, Closing Opp). Paste in seed order and the splits are clean.
There's a temptation to think a sport-specific or classroom-specific tool would be 'better' than a generic generator. In practice the opposite is true: the rules of fair team-splitting are the same whether you're dividing a Year 7 PE class or a Sunday-league football squad. What changes between audiences is the framing — the language used in the guide, the typical group size, the kinds of ratings people record. The underlying maths (Fisher–Yates shuffle, snake-draft balancing) is identical. That's why this site uses one generator across many audience-specific pages: the same engine, with copy and presets tuned to the context.
If you'll regenerate teams from the same roster repeatedly — every Tuesday training, every Friday game night — paste the names once, click 'Copy as text', and save the result in a note app or a pinned message. Next session, paste it back. There's no account system to maintain and nothing to forget; the names live wherever you keep your other notes. For coaches managing multiple squads, prefix each name with a one-letter squad tag (e.g. 'A Alex', 'B Sam') and use the filter step to keep only the relevant tag before generating.
Manually pair, then put each pair as one line and split into 2 teams.
Yes. The generator doesn't ask for personal information, doesn't display ads inside the tool itself, and runs entirely client-side. Many teachers use it weekly. See the trust and safety page for the full position on under-16 use.
Yes — the 'Export CSV' button gives you a two-column file (team, name) that opens cleanly in Excel, Google Sheets, and Numbers. From there you can pivot, filter, or merge with attendance records.
Add their name to the textarea and regenerate. If you want to preserve the existing teams and just slot the latecomer in, use the 'Add to smallest team' shortcut instead of regenerating — it places them on whichever team currently has the fewest members.
Drop in any list of names and we will split it into two even teams in seconds — random, or balanced by skill rating if you prefer.
OpenFour-team splits are the sweet spot for tournaments — enough variety for a real competition, small enough to fit in one afternoon.
OpenSeminar leaders and TAs — paste the attendance list and split into project groups in seconds.
OpenFrom escape rooms to scavenger hunts — split your team into mixed groups that don't just put the same desk-buddies together.
