Devntra
DebateMate
Train your argumentation against up to 6 AI opponents simultaneously — live voice, unique personalities, and a coach that scores every word you say.
Practice Debate at Scale
Great debaters are made through repetition — but finding human sparring partners with diverse argumentation styles is almost impossible. DebateMate was engineered to solve that gap at scale: an open-source platform where you can walk into a live voice debate room, face up to 6 AI agents each with a distinct personality, voice, and argumentation style, and receive a comprehensive AI performance review the moment you finish speaking.
Real-Time Multi-Agent Voice
LiveKit powers sub-100ms audio rooms where AI agents — Morgan (Moderator), Alex (PRO), Maya (CON), Jordan, and Riley — each speak with unique Murf TTS voices and argumentation personalities simultaneously.
Personalized Learning Path
Gemini AI curates a curriculum of logical fallacies, debate techniques, and argumentation theory — dynamically tailored based on your post-debate performance scores and skill gaps.
Agent-Orchestrated Voice Infrastructure
Devntra built DebateMate on a Next.js 15 frontend paired with a FastAPI Python backend, coordinated via LiveKit's Agents SDK. A custom Turn Manager rotates speakers with a fair PRO/CON algorithm, giving users priority every 3rd turn. OpenAI Realtime handles LLM responses, Deepgram handles STT, and Silero VAD detects speech boundaries.
LiveKit Multi-Agent Rooms
Each debate session spins up a LiveKit room where the backend deploys 2–6 AI agent workers simultaneously. The Turn Manager runs a fair PRO/CON rotation algorithm ensuring balanced debate flow with user-priority every 3rd turn.
Gemini Post-Debate Analysis
Full debate transcripts are analyzed by Gemini AI — scoring logic, evidence quality, delivery, and counter-argument effectiveness. Exportable to PDF with complete session history.
AI Mentor Chat
A personal AI coaching chatbot guides users between debates — explaining logical fallacies, suggesting debate techniques, and answering argumentation questions on demand.
Up to 6 AI agents with distinct personalities and voices debate in real-time via LiveKit voice rooms.
Post-debate Gemini AI analysis scores argumentation, logic, delivery, and provides actionable coaching notes.
Voice debates, text debates, AI mentor chat, learning path, and a performance analytics dashboard.
“DebateMate is the only tool that actually challenges my thinking in real time. Each agent argues differently — Alex is methodical, Maya is relentless, Jordan is passionate. After a 15-minute session, the Gemini feedback told me exactly where my logic broke down. Nothing else comes close.”
