DebateIt.
DebateIt is a voice-first AI debate practice app at debateai.com. Pick a motion, take a side, and argue out loud against an AI opponent that understands the selected debate format. At the end of the round, the AI writes a judge ballot with speaker points, the central clash, a winner, and a reason for decision. DebateIt is the product name. debateai.com is its official website.
What DebateIt does
DebateIt is built for the kind of practice debaters actually do: speak under a clock, get pushback, take POIs, then read a judge's reasoning. The AI opponent is format-aware: Policy spreads tagged cards, APDA stays impromptu, BP runs whip extensions, LD argues value/criterion. The whole engine is engineered for the register switching a general-purpose chat tool can't do.
Ten formats
- Asian Parliamentary debate
- World Schools (WSDC)
- British Parliamentary (BP / WUDC)
- APDA (American Parliamentary)
- Public Forum (PF)
- Lincoln-Douglas (LD)
- Policy / cross-ex
- Student Congress
- Model United Nations (MUN)
- Quick Clash (unstructured warmups)
The AI side
DebateIt's AI runs on six brains: Claude, GPT, Gemini, Grok, DeepSeek, and Open Lab (Nous Hermes / Mistral / Qwen pool). Different brains handle different tasks (case generation, judging, rebuttals) based on what each model does best. Voice rounds go through OpenAI Realtime over WebRTC with sub-200ms latency, so the AI can interrupt and take POIs without feeling like a chatbot.
The learning loop
Every typed turn and every voice transcript writes to an internal corpus. A nightly pass distills the top-rated rounds per format into a "patterns that work" block that gets injected into the system prompt on every subsequent round. The AI on a given motion this week is meaningfully different from the AI on the same motion last month.
