OpenAI today launched Codex for Chrome, a Chrome extension that lets Codex work directly in the browser on Macs and PCs.

With the extension, Codex can use the browser to test web apps, get context across multiple tabs, use web DevTools, and more without taking over the browser from the user.

OpenAI says that after it launched Computer Use in the desktop Codex app, it saw that most common workflows happened in the browser. The Chrome extension should make it faster and easier for Codex to help with browser-based work that plugins or APIs can't handle.

According to OpenAI, Codex has more than 4 million weekly active users, an increase of 8x since the beginning of the year. The Chrome extension is part of OpenAI's broader effort to make Codex more useful for work people do daily, while keeping it useful for developers.

The Chrome extension can be installed through the Codex Plugins menu.
