Real-time language speaking practice with real humans. Press one button, get matched in under two seconds, practice for five minutes — then get AI pronunciation feedback after every session.
Built like a realtime product should be: React Native for mobile, NestJS services, PostgreSQL + Redis for state, LiveKit for WebRTC, and OpenAI for post-session pronunciation intelligence. Designed for learners who want genuine conversation reps — not calendar ping-pong or chatbot cosplay.
