Everything you need for voice, on your machine
Seven TTS engines built in
Qwen3-TTS, Qwen CustomVoice, LuxTTS, Chatterbox Multilingual, Chatterbox Turbo, HumeAI TADA, and Kokoro — all bundled, all running locally.
Voice cloning in seconds
Record a short sample or upload a clip and generate speech in that voice. Your audio never leaves your device.
Whisper transcription
Drop audio files or dictate live — transcription happens locally with OpenAI Whisper (standard or Turbo) via PyTorch or MLX.
Live dictation
Hold a hotkey, speak, and have the transcribed text typed into any app. Works anywhere macOS accepts keyboard input.
Complete privacy
Models and voice data stay on your machine. No API calls, no cloud uploads, no telemetry — 100% offline once installed.
Apple Silicon + CUDA
Ships MLX-optimized weights for M-series Macs and CUDA builds for NVIDIA GPUs. CPU fallback works but is slower for larger models.
