OpenLingo – Connecting Sonnet 4.6 to a Duolingo-like interface

AI Analysis
●●SolidShip ItSolve My Problem
Duolingo alternative with persistent AI tutor—but no clear advantage over existing paid platforms.
Strengths
- •Persistent memory system lets AI tutor adapt across sessions, not just one-off chats
- •9 exercise types plus STT/TTS feedback rival commercial platforms' depth
- •SRS + AI tools (bulk import, auto-generation) reduce manual lesson creation overhead
Weaknesses
- •Free tier sustainability unclear; competing against Duolingo (200M users), Babbel (10M paid)
- •No evidence of user traction, retention metrics, or why this beats ChatGPT + Anki
