Gerty

Gerty is a private, local artificial intelligence assistant that runs entirely on Mac hardware without cloud connection.

Gerty is a private artificial intelligence assistant that runs open language models directly on a Mac chip rather than in the cloud. It interacts with local documents, mail, calendars, and files while keeping all data on the local machine. The application measures the host computer, selects appropriate models, and sets them up automatically for tasks such as chatting, writing, coding, and handling images. Users can operate the system completely offline, access it through a notch assistant interface, and connect it to various local tools. The software requires a Mac with Apple silicon and specific macOS versions, supporting up to three computers per licence.
