Atticus (GitHub SaarthurR/atticus-mac) is a free, open-source macOS assistant: hold Control-Option-Space, speak, and it arranges windows, finds files by content, reads the screen or types replies without sending them. It runs through Claude Code on an existing Claude Pro or Max plan with no API key, skips the model for simple asks and learns repeated actions.
