you disagree.
Whether it’s a club night or a showcase stage, every SuperDebate follows the same simple idea.
A fair question
Every round starts from a resolution both sides can accept.
Two real cases
Each side gets equal time to make its strongest argument.
Meaningful clash
Each speech responds to the last one, so the arguments clash instead of talking past each other.
Insight, not just a winner
The room scores the exchange, and everyone leaves seeing the question more clearly.
Clubs
A club for people who love a good argument.
Clubs meet in person and online, and first-timers are always welcome. You can watch a round, take a side when you’re ready, and stay for the conversation afterward.
Debate online
Debate anywhere, practice anytime.
Live video rooms for real opponents, and an AI sparring partner for the hours in between.
