The Problem

Duolingo-style tap-to-translate apps build vocabulary but do not build speaking fluency. Real conversational practice requires a patient, always-available partner who can understand learner speech, respond naturally, and correct mistakes in context, at a price point UK schools can actually deploy.

The Solution

Apex36 built the first AI-avatar language-learning app of its kind: live video-call tutors powered by a realtime STT → LLM → TTS pipeline at conversational latency. A video-avatar interface gives learners a consistent AI persona, closer to a human tutor than a chatbot, and conversational context retention lets the AI hold multi-turn conversations, reference earlier statements, and personalise drills. The product is packaged for UK school procurement.
