Building Plan — Step-by-Step Execution
TBD
Prototype the Core Lesson Engine (No-Code / AI Assisted)
$0–30/month
Build the addictive micro-lesson flow with gamified exercises (vocab, grammar, listening, speaking). Use AI to generate initial lesson content for one rare language (e.g., Estonian). Focus on streaks, XP, hearts, and instant reward feedback.
Tools:
Lovable.dev, Bolt.new, v0.dev, FlutterFlow (for mobile feel)
APIs:
OpenAI/Groq for lesson generation, ElevenLabs or Google TTS for audio
Add User Onboarding & Gamification Core
$10–60/month
Create auth, daily streak tracking, XP/levels, leaderboards, and hearts system. Implement progress trees per language. Store user stats and lesson history.
Tools:
Supabase or Firebase for backend/auth
APIs:
Supabase (auth, DB, realtime for leaderboards), Stripe for future payments
Integrate Speech Recognition & Listening Exercises
$20–80/month
Add speaking practice with instant feedback. Use speech-to-text for pronunciation scoring and listening comprehension.
Tools:
Web Speech API (free starter), Whisper via Groq/OpenAI
APIs:
Groq Whisper for fast speech recognition, ElevenLabs for native voiceovers
Build Freemium & Subscription Layer
$25–60/month
Implement free daily lessons (limited hearts) vs. Super subscription (unlimited hearts, offline mode, ad-free, bonus XP). Add streak freeze and cosmetic rewards.
Tools:
RevenueCat (mobile) or Stripe Billing (web)
APIs:
Stripe Checkout, Lemon Squeezy for simpler no-code
