Google Chrome’s grip on the web is ridiculous. It sits on top of the browser market so comfortably that most new challengers barely register.
ChatGPT Atlas was one of those launches I didn’t notice properly at first. Then I saw where OpenAI seemed to be heading with it.
In March 2026, the company said it plans to combine Atlas, the ChatGPT desktop app, and Codex into one desktop workspace led by applications chief Fidji Simo.
That was enough to make me try it. So I closed my Chrome tabs, paid $20 to OpenAI, and used Atlas as my main browser for a few weeks. Here’s what happened.
I tried Chrome, Opera, Firefox, and Samsung Internet for a month and here’s my verdict
The ultimate browser showdown is finally here
OpenAI made switching from Chrome surprisingly painless
What surprised me first was how familiar Atlas felt. OpenAI built it on the open source Chromium project with the Blink engine, and you notice that right away.
The layout, settings, shortcuts, and general web behavior don’t resemble a weird AI experiment trying to reinvent browsers.
That also carries over to the setup. Atlas imports your Chrome bookmarks, passwords, browsing history, and settings.
Even extensions are part of the picture, with OpenAI adding extension import during onboarding and extension management inside Atlas.
People want their browser habits to survive the switch. A browser that breaks muscle memory is dead on arrival.
Atlas gets interesting when ChatGPT joins the page
The engine choice is not the interesting part. Blink already handles most global browser sessions. What matters is the AI layer Atlas puts on top of it.
Atlas can pull out the details from your current tab so you can query it.
Cursor chat is another small but useful touch. Highlight text in an email draft or web form, and ChatGPT can rewrite it inline.
It sounds minor until you stop doing the old copy, paste, rewrite, paste-back routine. I really wish more AI tools added such everyday conveniences.
Atlas can browse for you, but patience is required
Atlas’s most interesting feature is Agent mode. I don’t mean interesting as in automatically good, and I’ll explain why.
When active, Atlas shows actionable elements of the page in blue, which makes the assistant’s reach easier to understand.
It then uses a digital cursor to move through tasks. For example, it can find a specific product you mentioned and put it in your cart. Then it moves you to the checkout screen.
OpenAI has guardrails around the scary parts. Atlas will ask for human approval before sensitive actions like submitting a payment.
Agent mode also runs inside a sandbox, so it cannot run arbitrary code, download files, or reach into the local file system, for example.
Agent mode definitely has potential, especially for accessibility or for running a task in the background while you do something else.
But if you sit there watching it work, you quickly notice how much slower it can be than a person. At least, that’s been my experience.
Agent mode is not free. Atlas works on free accounts, but Agent mode requires Plus, Pro, Business, Enterprise, or Edu subscription tiers.
AI browsers could make websites easier to ignore
There’s also an issue here for publishers and the open web. A traditional browser helps you reach a website.
Atlas digests that website and often gives you the useful part of the page without making you visit it in the same way.
Google’s AI Overviews raised similar concerns because they extract publisher content and present it inside search.
The difference is that Google still has a business reason to send traffic out. Atlas seems more comfortable keeping the user inside ChatGPT.
Atlas is good, but Chrome is still everywhere
The biggest practical issue is availability. Atlas requires an Apple Silicon Mac running macOS 14.2 or newer, and Intel Macs are excluded.
OpenAI says Windows and mobile versions are on the way. For now, though, Atlas still can’t match Chrome’s reach across personal and work devices.
Maybe Atlas can earn a place as a research tool for people already paying for ChatGPT, especially for page analysis or boring web chores.
But for everyday browsing, it still has plenty of ground to make up. Because of that, especially when security is part of the equation, Chrome still wins.
I use ChatGPT every day, and I think it’s brilliant. If OpenAI eventually brings Atlas to mobile, I’d be tempted to try it again. But for web browsing, I still prefer Chrome’s reach across all my devices.
