Sanctum AI is a local AI assistant for Mac that runs entirely on your device and doesn’t require an internet connection. Data is encrypted and stays on the machine, which makes it a fit for privacy-sensitive work. The app supports running different open-source language models, so you can choose the model that best matches your tasks. Setup is designed to be quick, with a straightforward interface.
What it’s for
