Konjac is an on-device AI speech toolkit: live transcription, natural text-to-speech, two-way conversation interpreting, pronunciation practice, and translation โ€” with the core models running on your iPhone and iPad. PRIVATE BY DEFAULT The built-in speech and translation models run locally on Apple Silicon, so the core features work offline and your audio stays on your device. No account required. No ads. No tracking. FEATURES - Live: real-time speech-to-text with optional auto-translation - Bridge: hold a two-way, face-to-face conversation across languages - Voice: turn text into natural-sounding speech with multiple voices - Practice: phrasebook drills and pronunciation scoring - Translate: fast text translation across many languages OPTIONAL CLOUD PROVIDERS Prefer a specific engine? You can optionally connect your own provider โ€” such as Gemini, OpenAI, Azure, Deepgram, ElevenLabs, or Google Cloud โ€” using your own API key for extra languages and voices. Cloud features are off by default; when you enable one, data is sent only to the provider you choose. Universal app for iPhone and iPad. Konjac keeps everyday speech and translation fast, private, and in your pocket.
