The TalkBoardVR classroom: a teacher stands at a blackboard in a sunlit Japanese classroom, with a floating conversation panel reading "Push T to talk" and an options panel for language, difficulty and speed.

TalkBoardVR

Unity · ASP.NET Core · 2025–present

A 3D language classroom where you practise speaking with an AI teacher. Speech is transcribed, answered by a language model, and spoken back in the target language, with flash cards and quizzes drawn from the same vocabulary. Players bring their own provider keys, which never reach the headset — every call is proxied server-side. Live in public beta for desktop browsers and closed beta on Meta Quest.

Industrial corridors and walkways under the station's outer hull. An open bay of the station with machinery and starfield beyond.
