ChatGPT To Codex is a desktop app for macOS and Windows that gives ChatGPT the ability to actually work inside a project folder on your own computer, instead of just talking about code. You install a small local runtime, pick a project folder you trust, and connect it to ChatGPT through a local server. From there ChatGPT can read your files, search your code, apply patches, run your tests, start a local dev server, and even take screenshots of the running app or website to prove that something works. Your source code stays on your machine the whole time. Instead of uploading a copy of your project anywhere, ChatGPT reaches out to the app running locally on your computer, and you decide which folder it can touch and approve a connection token before anything happens. The idea the project describes is simple: ChatGPT thinks, your computer acts, and you review the result. One highlighted workflow is asking ChatGPT to run an end to end test, open the app, capture screenshots of it, and show you the proof directly in the chat. For web apps it can capture parts of a browser window, and for desktop apps built with frameworks like Tauri it can open the built application and capture different views of its window. Setup involves downloading an installer package for your operating system, opening the app from a menu bar or system tray icon, choosing a project folder, starting the local connector, and then registering the resulting connector address inside ChatGPT along with an approval token that the app generates for you. That token should be kept private, similar to a password. The project describes several safety measures: it only listens on your own machine by default, file access is limited to the folder you selected, patches are applied using careful line and content checks, values that look like secrets are hidden from the tool's output, and riskier actions still require your approval. The app's interface supports around twenty languages, and its install guide is currently available in a smaller set of languages including English, Korean, Japanese, and Simplified Chinese.
