AI Language Tutor App — Real Conversations, Real Corrections
Practice speaking any language with an AI tutor that corrects your grammar, accent, and word choice in real-time.
The Problem
Language apps (Duolingo) teach vocabulary, not conversation. Human tutors cost $20-50/hr. Speaking anxiety prevents practice. No app combines AI conversation + real-time pronunciation feedback.

After 3 years of Duolingo I still freeze when trying to speak with native speakers. The app never taught me conversation
Language learning is a $20B market and it's all gamified vocabulary apps. Where is the AI conversation practice?
