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.

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

Is that you Sam? We don't have to like it when you are replacing employees with GPUs? But it has to happen because it makes the world a better place?

OpenAI, Chrome, VScode, CoPilot, Microsoft, APIs, Github, Claude, TokenBurn, User agreements, blank passwords, AGIs, OpenClaw, Pentagon, deleted emails, databases, Sam Altman. Just chuck it into a search engine and see what pops up. If just 20% of the results are based on facts.... well allow me the question: Is it trustworthy?

Suddenly Apple delaying AI Siri seems like a "healthy" longterm strategy.

I like the way you drew a line under technology that helps you get things done quicker at phone and computer.

Why no Safari extension though :/

Global Market Share Breakdown (April 2026)
Google Chrome: ~67.97%
Safari: ~17.09%

I don't know about other developers but I test what I'm doing as I'm doing it only on one browser and then, maybe, on a second one to check. It wouldn't be smart to do it on the one that 1/4 of people use.

Working with codex, I keep saying this.
People who think AI is just crap are those that only see useless features like the Whatsapp button, slop videos and articles.

I guess it depends?
Mobile games companies, for example, when they are going to test a market for a new game, they tend to use a smaller sized sample like soft launching in Philippines (don’t know why there became popular for that) which is a small fraction of the world’s market, likely skewed on the hardware and software phone install base, and all that. After its successful there then they roll to larger markets.

I guess with safari and chrome, it can make sense to “test” on a minimal common denominator slate knowing that if it works there it will likely also work elsewhere at scale.

Indeed. The comment sections of everything AI (which has been substantial daily news for some time now) is full of actors that aren’t the target and aren’t interested in it, but are calling it the bubble bursting, predicting that -it doesn’t work nor will never work and it’s completely useless- since GPT1 days.

Seven years later, GPT 5.5 and Co, with the equivalent Chinese versions and all already out… and it’s still the same. Sure, “it hasn’t replaced the truck drivers, carpenters and plumbers and all humans” yet, and I hope it doesn’t and honestly I don’t think it will any time soon, but still.

The logic riddle goes like this: if the thing is so useless, if it is “bursting any time now”, if it will catastrophically fail by this weekend… why constantly call that and mention it for seven+ years straight? If it is so uninteresting, why such a heated interest in saying that it is uninteresting?

I’m confident there are many more useful and interesting things to do during the hours of our limited lifetime we got on this earth (like family, hobbies, movies, exercising, games, friends, etc) than bash and complain without pause on something so “useless and sloppy” that will be no more any time now.

Yeah, for sure, but I was just explaining why the priority on Chrome and the numbers are very clear. Not saying Safari would be useles, just useful for less people, probably. Or, anyway, just not even allowed on so many devices, while Chrome runs everywhere. If they had to choose one, it just had to be Chrome.

I also guess that we're not in 2005 and testing different browsers in every phase isn't a terrible mistake anymore. Back then, some developers put pop-up banners in their websites that could detect Explorer users and tell them to download a more serious browser like Firefox. Nowadays, I don't even remember the last time I tried something on a browser and it didn't work properly on another one.
 
So basically, Walmart still wants to track my snack habits, but I can't tap Apple Pay? Meanwhile, Codex can now track all my browser chaos… priorities, Walmart.
