• ProblemBuild a trainer people want to come back to and find out what users are willing to pay for.
• What I did
  • City scenes in a blueprint-style 3D look, courses and a trainer.
  • An AI conversation partner: the server builds the prompt from whitelists, the AI key has a daily spend limit, and the free tier gets a few replies a day.
  • Progress sync across devices.
  • Studied the market: people pay for live voice conversation without their own key, most of all for English for IT interviews and relocation.
• ResultLaunched: users are already exploring new cities. Paid plans are being prepared.
• Stack and approachWeb app, AI through a gateway with limits, cloud sync.
