Markup over Gemini API cost (sustainable pricing)

iOS+Android

Capacitor wrapper, single codebase

Voice

First-class, not text-with-TTS bolted on

Mint

Production-safe token mint endpoint

Architecture

Vite + React + Capacitor — same codebase ships iOS and Android
Gemini Live API — voice conversation with structured lesson plans
Credits wallet — server-side balance with secure token mint
Free trial credits — onboarding flow without requiring payment

How it works

The user speaks. Gemini responds in the target language. The credits wallet debits per second of conversation. Tokens are minted server-side only, never client-side.

Hard rules: never store conversation audio beyond the active session, never log Gemini API keys client-side, never mint tokens without auth, never bypass the credits gate for production flows.
