How a debate works

  1. Match & motion — pick your topic (or roll a random one) and choose FOR or AGAINST. You're paired with an opponent who wants the other side. Queue ranked (signed in, rating at stake) or casual.
  2. Live video debate, 5 minutes — you go face to face on camera, and anyone can drop in to watch and hear you live. No turns: speak, interrupt, fire back. Typing works too, as a fallback. Your mic audio is recorded during the debate and transcribed by AI the moment it ends — that transcript is the official record. Need more time? Extensions add +5 min each when both sides agree, up to 20 minutes total.
  3. Fact-check — factual claims in your arguments are detected and checked against Wikipedia and news sources; the results feed into the verdict.
  4. The verdict — the audience result shows instantly; the AI judge then scores the transcript on argument quality, evidence & accuracy, rebuttal engagement, clarity and conduct out of 100 (it takes a few moments while your audio is transcribed). Resting your case concedes. In a rematch the judge also sees a short summary of your previous match, so developing your arguments pays off.
