OpenAI jumped into the browser wars today with ChatGPT Atlas, which puts AI at the center of your web surfing, but only on macOS to start.
Atlas, which is free to download, is built on Google’s Chromium engine and operates like other browsers, offering traditional features such as tabs, bookmarks, password autofill, and an incognito mode. Still, it promises to stand out from the competition by integrating OpenAI’s chatbot into the browsing experience.
That means users will no longer need to copy and paste information from the web to the ChatGPT app or domain. Instead, easy access to the company’s chatbot is baked in across the browser’s interface, tabs, and the cursor pointer. OpenAI demonstrated this in a live stream, showing that you can highlight some text in your email inbox, click the “ChatGPT nub,” and ask the chatbot to improve some pre-written text in an email.

This can include summarizing a movie review on the left-hand side or analyzing some computer code, although OpenAI’s demo showed the result might not always be accurate, meaning you’ll need to watch out for hallucinations.

The ChatGPT Atlas homepage is also designed with a recommendation engine that’ll present websites and content for you to view based on your browsing habits.

The browser memories feature also raises questions about privacy. A support page says ChatGPT Atlas's browser data can be used to improve the company’s AI models, but the feature is off by default. “Browser memories do not include your passwords or payment details, and they are separate from cookies and site storage,” the company added, noting that users can also delete browser memories.

In a demo, the agent mode was able to develop a list of the ingredients necessary for a recipe, access the user’s Instacart account, and place them all on the add-to-cart page for checkout. That said, the process took a few minutes to complete.
To guard against the AI making mistakes or posing a security risk, the agent mode only has access to browser tabs and has been blocked from executing computer code or accessing files on your PC. "You’re always in control: ChatGPT is trained to ask before taking many important actions, and you can pause, interrupt, or take over the browser at any time," the company adds.
For now, the agent mode is only available for paid users who’ve subscribed to ChatGPT Plus and Pro. We’ll be curious to see how ChatGPT Atlas performs and if it can disrupt Google’s dominance of the web browser market. Currently, Google Chrome has a 71% share of the browser market, with Apple’s Safari a far-off second, according to StatCounter.
Google is already integrating its Gemini chatbot into Chrome, while Microsoft has also been doing something similar with its Copilot AI across the Windows OS and in Edge.
OpenAI says it plans on expanding ChatGPT Atlas to Windows, iOS, and Android “soon.” A support page also notes that ChatGPT Atlas can import data from other browsers.
