Why Privoca? • On-device AI: core tutoring and ASR run locally—your data stays on your phone • Scenario-based learning: speak in context, not isolated word lists • Great for commutes, travel prep, and last-minute speaking practice First-time setup To keep the install size small, Gemma and WhisperKit models are downloaded inside the app on first launch (~3GB).
