Rifflet turns a short music idea into a playable lesson. Type a prompt, generate a local sound, pick Piano, Guitar, or Ukulele, follow the notes as keys or tab, hear local instrument playback, and save or share the riff card. The app is intentionally simple: local audio generation, coach tips, saved riff ideas, piano playback, and guided practice views. It does not require an account, network login, or cloud AI key.
