Models on your Mac
Download language models to your Mac to translate and summarize offline, and pick a model to fit your RAM.
- macOS
Besides Apple's and the cloud engines, your Mac can run local language models to translate and summarize entirely on your device, with no network needed after the download. Your data never leaves your Mac.
Download a model
- Open Local models in the sidebar.
- In the Available to download list, click Download next to the model you want. You can Resume if an earlier download was interrupted, or Cancel.
- When the download finishes, the app asks Use as your default?. Agreeing sets the model for Translation and Summary.
Models are downloaded from Hugging Face and stored in the app's data folder. The top of the screen shows the space used. To remove a model, click Delete (you can't delete while recording).
Choose a model by RAM
Each model shows a badge, Fits available memory or Needs ~NGB free, based on how much memory is free at that moment.

Sonasi TTS

Offline speech recognition
Local models are used only for Translation and Summary. Offline transcription uses Apple's Default engine.
