About PolyTune

Polytune translates and romanizes lyrics of niche or underground tracks.

PolyTune is a production-ready mobile app that delivers real-time synchronized lyrics, zero-latency phonetic romanization, and AI-powered translations for global music fans—specifically targeting J-Pop, K-Pop, Phonk, and underground tracks ignored by mainstream platforms.

Next step: You can turn synchronized lyrics into an interactive study tool by adding tap-to-translate vocabulary lookups or AI-generated flashcards. You can swap in your own RevenueCat and Google Sign-In API keys, and other secrets, run the clean Expo build, and publish directly to the iOS App Store and Google Play Store.The core architecture uses local Edge Function romanization and a Supabase PostgreSQL cache shield, meaning user requests stream for $0 once cached.
