How it works

    
One chatbot is one opinion — and chatbots can confidently get things wrong. Mass Debates makes four AI models argue it out: each answers blind (no copying the confident one), then they attack each other’s reasoning, and a judge hands down one verdict with an honest confidence score. Answers are cross-checked, not just generated.

    
Quick verdict — straight blind answers, quick ruling. The daft-argument settler.

    
Full debate — adds the clash round: rebuttals, concessions, and devil’s advocates stress-testing the consensus.

    
Power — the full clash plus a fact-check pass rating the claims the answer actually rests on.
