Anyone can argue. Few can win.
Five minutes, face to face, against a real opponent. Your claims get checked against public sources. An impartial AI judge decides who actually made the better case.
Choose your debate

One shot a day: make your case in up to 100 words and the AI judge scores it out of 100.
One entry per day. Your argument and display name can appear on today's leaderboard.

Five minutes. One verdict.
- 01
Pick a side
Choose a motion, or take a random one, and argue FOR or AGAINST. You're matched with someone who wants the other side, ranked or casual.
- 02
Argue for five minutes
Face to face on camera, voice only, or text. No turns: speak, interrupt, fire back. If you both agree, add five minutes, up to twenty.
- 03
Get fact-checked
Factual claims are checked against Wikipedia and the news. Results stay hidden until the end, so you argue with each other, not the checker.
- 04
Hear the verdict
The audience votes live. Then the AI judge scores both sides out of 100 and explains why. Rest your case early and you concede.
No video is ever recorded. Cameras are live only. Your mic audio is kept just long enough to be transcribed when the debate ends, then deleted; the transcript is the official record. In a rematch, the judge also sees a short summary of your last match, so developing your arguments pays off.
Scored on substance, not volume
Argument quality
Is the reasoning sound, and does it address the motion?
Evidence & accuracy
Are claims specific, and do they survive the fact-check?
Rebuttal
Did you answer what your opponent actually said?
Clarity & delivery
Could a stranger follow your case?
Conduct
Hard on ideas, civil to people.
Bias checkThe AI judge reads every debate twice, with the sides swapped. If the two readings disagree, the debate is called a draw.
Searching for an opponent…
You'll be matched with someone near your rating. The search widens the longer you wait.

Tournaments
Single-elimination cups. Sign in, join an open cup, and when it fills the bracket is seeded by rating. Win your match to advance — the judge's verdict decides, and draws advance the higher seed.
How tournaments work
Random Cup
- Auto-opens weekly; 8 players.
- Every match gets a random motion and random sides.
- Matches are ranked (ELO) — the judge's verdict advances you.
- A draw advances the higher seed.
- Both players click "▶ I'm ready" to start a match.
- The champion earns the achievement.
Themed Cup
- Started by admins on one motion (often a trending topic).
- You pick FOR or AGAINST when you join — slots are balanced (half each).
- It's a league, not a knockout: every debate pairs FOR vs AGAINST and you always defend your chosen side across several matches.
- Scoring: 3 points a win, 1 a draw, 0 a loss.
- Separate FOR and AGAINST standings — one bad matchup never eliminates you.
- When every league match is done, the top FOR and top AGAINST debater meet in the Grand Final. The champion earns the Champion achievement.
