OpenAI's Codex Now Works in Chrome With New Extension

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.

I'm going to install this OpenAI plugin as well as Perplexity on all of my machines. I'm sure nothing will go wrong. Sam Altman is a trustworthy guy.

Everyone can bash on this all they want but CODEX is the real deal. Works amazingly well and is 99+% accurate. People can hate AI or just use it and realize its capabilities as they will be left behind just like businesses are using it more and more and replacing employees with GPUs. We don’t have to like it, but AI coding is really good now versus just six months ago.

So just because some of us are not going to use this stuff we are being left behind in your opinion?
Some of us don't use things because other people are or because we are told we should.
I don't need AI on my computers or phones, which is why it is disabled, so why would i install something on my computer/phone that has AI on?
Also, i don't use Chrome, even one my Android phone
