Argue one-on-one against an AI opponent.
Pick a question, take a side, and the AI takes the other. The clock is simple, interruptions are natural, and the judge explains what won when the round ends.
One casual round type
- One person per side. No teams or partner setup.
- Plain language. No tournament format or circuit jargon.
- A real exchange. Each side builds a case, answers the other side, and closes.
- A score out of 100. Argument strength, responses, and clarity determine the total.
What you get back when the round ends
A clear judge's decision, scored out of 100. Example excerpt from a round about domestic semiconductor manufacturing:
The For side wins, 88 to 82. Central clash was supply-chain resilience versus fiscal opportunity cost. For carried weighing on probability and timeframe: their CHIPS Act precedent argument was clean and gave specific 2024 build numbers (Arizona TSMC fab, Ohio Intel). Against's spending tradeoff was warranted but never weighed against the cost of a Taiwan strait disruption, which For extended in summary. Drop in final focus: Against's "private capital is sufficient" claim was rebuilt in their summary but the warrant (Morgan Stanley 2023 analyst note) was misrepresented per For's cross. To fix: collapse earlier in summary; signpost weighing before reading impacts; tighten the second contention into one analytic chain.
Casual by design
Debatable is for people who want to argue something out. Every public round is casual 1v1, with one person on each side and a plain-language decision at the end.
