Open Source Licenses
Tonota uses open-source libraries to run transcription and local AI features on device. This page preserves their copyright and license notices.
Model files have licenses separate from the app and library code. Please review the license for each model you choose to download or use.
Model Notices
Tonota downloads AI models only when you choose to install them. The currently referenced model sources are:
- Speech recognition: models from argmaxinc/whisperkit-coreml, based on the OpenAI Whisper model family.
- Local LLM polishing: models are not bundled with Tonota. Users can choose to download options such as Qwen3 0.6B 4bit, Qwen2.5 1.5B Instruct 4bit, Qwen3 1.7B 4bit, and Qwen3 4B 4bit.
- Optional/custom LLM models: if you enable additional models from the MLX registry, those models keep the license shown on their own Hugging Face model card.
The Qwen2.5/Qwen3 MLX community conversion model cards identify their license as Apache License 2.0 and link to the upstream Qwen license files.
