👋 Hey Product Hunt! I’m the founder of **AI Debate Arena**. I’ve always loved debating — but organizing a proper 4v4 debate usually means finding 8 people, a judge, and a room that everyone can agree on. It’s hard. So I built a platform where anyone can practice structured debates anytime, anywhere — powered by AI opponents and AI judges. The goal was simple: make debate training as easy and accessible as writing practice essays or doing coding challenges online. This project started as a small weekend prototype and turned into something I now use myself to stay sharp in argumentation and critical thinking. It’s been a fun mix of education, AI, and product design. Would love to hear your thoughts — especially from teachers, debaters, or anyone working on AI education tools. Thanks for checking it out! 🙏

Hey everyone! 👋 Winfield Feng, founder of AI Debate Arena.

I built this to make structured 4v4 debate practice easy — no scheduling, AI opponents + 3 AI judges that score logic and persuasiveness.

Would love feedback from debaters, teachers, and anyone into AI edtech.
