An independent open-source project called Atticus is offering Mac users a voice-driven interface for controlling desktop tasks through Claude. The software is designed around a hold-to-talk shortcut: users press Control-Option-Space, speak a request and release the keys to send it. A toggle mode is also available for longer requests.

According to the project documentation, Atticus can move windows, locate files and read information displayed on screen. It also supports learned shortcuts and a group of instant commands that can execute without sending a request to an AI model. The developer says the application uses a user’s existing Claude Pro or Max plan and does not require a separate API key.

The interaction design includes several safeguards around speech recognition. Apple’s final transcription is used to confirm a request before AI tools or learned shortcuts are allowed to run. Although model reasoning may begin during a pause, tool execution waits for that confirmation. If transcription takes too long, the application presents partial text for review. Users can cancel listening with Escape, stop a response by pressing the shortcut again, or edit and resubmit a previous request from the overlay.

Atticus also includes monitoring features intended for tasks that take time. The documentation gives examples such as watching a page until a shipment status changes or notifying a user when a coding agent finishes. These checks run locally at five-second intervals without repeatedly invoking an AI model, although the relevant window must remain open for webpage monitoring.

Installation places the software and its supporting files in user-level directories, builds an application in the user’s Applications folder and configures it to start at login. Initial setup checks the user’s Claude plan and requests the macOS permissions needed for its features. Settings cover the shortcut, voice, model, screen access, memory and usage. The repository also documents self-tests and offline regression tests for developers.

The project is distributed under the MIT licence. Its documentation says anonymous usage counting is disabled unless a PostHog key is supplied through the environment, and describes an optional once-daily random identifier that is not tied to the user. Requests and screen contents are not included in that count, according to the developer.

Atticus remains a third-party project rather than an Anthropic product. Its broad desktop permissions and ability to act on screen content mean prospective users should review the source, requested permissions and local data handling before installation.
