Developer Pedro Shakour has released an open-source iOS client for Grok Build, allowing users to control xAI agents remotely from an iPhone by connecting to a local Mac host.

Key Points

• The project uses a WebSocket-based ACP protocol to link an iOS SwiftUI application with the official Grok CLI running on macOS.
• Requirements include Xcode 16+, iOS 17+, and a valid xAI API key to facilitate communication between the mobile device and the agent.
• The iOS app functions as a remote pager, while the primary agent runtime remains hosted on the Mac for processing.
• The software is distributed under the Apache-2.0 license and is currently available for sideloading or simulator use rather than via the App Store.
• The repository includes scripts for smoke testing and a stub mode that allows for interface demonstrations without requiring an active API key.

Why it Matters

This project provides a functional mobile interface for xAI's Grok Build, enabling developers to interact with agents away from their primary workstations. By offloading the agent runtime to a Mac, it demonstrates a flexible architecture for managing AI workflows through a portable, touch-based remote control.
