# Requirements

> Mumble Dictation needs a Mac with Apple Silicon on macOS 14.2 or later. We recommend 16GB of memory or more; 24GB or more gets the best results.

Mumble Dictation needs a Mac with Apple Silicon (M1 or newer) running macOS 14.2 or later. We strongly recommend 16GB of memory or more; 24GB or more gets the best results. Intel Macs are not supported.

## Memory

Everything in Mumble Dictation runs on local models, so memory decides how much your Mac can handle:

| Memory        | What to expect                                                                                           |
| ------------- | -------------------------------------------------------------------------------------------------------- |
| 24GB or more  | **Recommended.** Runs the higher-quality language model, so cleanup and AI Actions give the best results |
| 16GB to 24GB  | Fully supported. Everything runs on your Mac with the lighter language model                             |
| 8GB to 16GB   | **Not recommended.** Speech to text runs on your Mac, but the AI layer needs your own AI provider key    |
| Less than 8GB | Not supported                                                                                            |

<Warning>
  On a Mac with 8GB to 16GB, the models compete with your everyday apps for
  memory, which can slow your Mac down and use more battery. Dictation still
  works and stays private, but for a smooth experience we strongly recommend
  16GB or more.
</Warning>

## Disk space

The models download once, right after install:

* Voice models: about 2GB. Dictation is ready as soon as these finish.
* Language model: about 3.4GB (16GB Macs) or about 5GB (the higher-quality option for 24GB+ Macs). It powers cleanup and AI Actions and finishes downloading in the background.

Plan for roughly 6GB of free disk space in total. Models live inside the app's own folder and are removed when you delete the app's data.

## Internet

You need a connection to download the app and the models, and for the online voice actions (Open, Ask, GIF). Everyday dictation, cleanup, and the other AI Actions work offline once the models are installed.
