One question. Two people.
Argue it out.

The AI judge explains the result and scores the arguments. Ranked results appear on the leaderboard.
What "This House" means
Some topics start with This House would or This House believes. It is an old parliament habit. "This House" just means whoever has the power to act, usually a national government. Nobody has to pick a country unless you both want one.
If the topic says This House would ban X, the person arguing for it says the ban should happen. The person arguing against says it should not. You do not have to prove a law would pass. You argue whether it is a good idea.
Believes means it is a claim about what is true or right, not a plan. Regrets means the thing already happened and you argue whether it was a mistake. Would means assume it happens and argue about whether it should.
Something in common.
Something to disagree on.
Tell the Match Desk what you like talking about and where you stand. You can skip questions. Matching prioritizes shared topics and different answers among people available to debate.
The AI uses that disagreement to suggest a question for your round. Both people can change it. Want a fresh idea? Press Debate something else. With both people’s agreement, the AI listens to what you want to discuss and suggests a question for you both to accept.

2. A person with a different take
Opinion opposition matching looks for useful disagreement. First available and closest rating are options too. Availability determines who can meet you.
3. A question you both choose
A suggested question starts the conversation. It does not assign you a belief. You can concede a point, question the framing, or choose another topic.
Matching answers are not the judge’s evidence. The judge evaluates what is argued in the round.

A tour of a round, from joining to reading the decision. Some controls have moved as the site has changed.
A few practical things.
Do I need to know how to debate?
No. Make a point, explain your reason, and listen to the reply. You can have a natural conversation or take timed turns. One person is on each side.
Do I need an account?
Sign in to start an AI round and keep your history across devices. Live video requires sign-in with Google, Apple, or email.
What if nobody is available?
Keep the live queue open, enable match alerts, or invite a friend. You can also start an AI voice round whenever you want. An AI opponent is always labeled.
Can people watch or record me?
Public live rounds can have spectators. Private invite rooms stay off the public board. Recording asks everyone in the room for permission before it starts. You can leave, report, or block someone from the room.
What does the judge use?
The judge reads what both sides said and explains its decision. It considers arguments and responses, not which side it prefers. Ranked rounds use the published panel and rubric. You can read the method and appeal policy on the judge integrity page.
What does it cost?
A Free plan is available. Private round judging includes two free uses per account, then requires a paid plan. Other limits and subscriptions are listed on the pricing page.
Where do my rounds go?
