wtf is grok-build-desktop?

Grok Build Desktop is a desktop application that lets you run an AI coding agent against projects on your own computer, using models served locally through Ollama instead of a cloud API. It is built with Tauri, React, and Rust, and it is still in early, active development, so it is aimed at developers who are comfortable building it from source and reviewing how it asks for permissions. The core idea behind the project is keeping control on the user's machine. The part of the app you see and click on, the React interface, cannot directly touch your files, shell, credentials, or Git history. All of that sensitive work happens behind a separate Rust program that checks permissions first. If the agent wants to run a terminal command, you get an explicit, time limited approval step, and you can take back control of the terminal at any point. Changes the agent makes to your code happen in a separate, managed Git worktree rather than your actual checkout, so you can review the exact changes before accepting or rejecting them. Right now, the project only supports Ollama as a model provider, though the design keeps the agent logic and the model provider separate on purpose, so other providers could be added later without redesigning how permissions work. Sessions are saved so you can pick up where you left off, and the app tracks crashes so it can recover cleanly. The interface currently ships in both English and Chinese. To try it, you need macOS, Rust, Node.js, pnpm, and ideally a local Ollama installation with at least one model downloaded. You then clone the repository, install dependencies with pnpm, and run the desktop app in development mode, or run the test and build commands separately to check the frontend without opening the full app. The project is explicit that some features are not finished yet, including broader support for other model providers beyond Ollama, full handling of write conflicts, and signed release builds people can install without compiling anything themselves. It is described as an independent layer built on top of a runtime originally published by SpaceXAI, and it is not an official product of xAI or SpaceX. The README is longer than what was shown.
