Sentient OS

macOS assistant that runs its own model on the Mac to learn from the notes, messages, mail, calendar and files the user enables, keeps that knowledge as plain files on the Mac, and then drafts replies in the user's voice, prepares overnight suggestions and carries out tasks with its own cursor, using the user's choice of ChatGPT, Claude, an API provider or a local model.
