OpenAI has officially launched a new web browser, ChatGPT Atlas, that places its flagship chatbot ChatGPT at the core of the browsing experience. Atlas is now available globally on Apple’s macOS today to Free, Plus, Pro, and Go users and will soon be available on Windows, iOS and Android, according to the announcement published on 21 October 2025.
Atlas has ChatGPT built into its system, meaning that it will support past conversations to assist users in their goals. Through the ChatGPT sidebar, users can also request it to “summarize content, compare products, or analyze data from any site.”

The company says the browser allows ChatGPT to “come with you anywhere across the web—helping you in the window right where you are, understanding what you’re trying to do, and completing tasks for you, all without copying and pasting or leaving the page.”
Key features include “Browser memories,” via which ChatGPT can recall context from visited websites and use that information later. For instance, you could ask ChatGPT: “Find all the job postings I was looking at last week and create a summary of industry trends so I can prepare for interviews.” This function is optional and gives users complete control, letting them archive entries or clear their browsing history, which automatically deletes any linked memory data.

Atlas will also introduce an “Agent mode,” currently available in preview to Plus, Pro and Business users, that enables ChatGPT to perform tasks on behalf of the user within the browser — such as researching and analysing, planning events or booking appointments while browsing. OpenAI says it has built in safeguards against risks, including access to sensitive data and unapproved site usage.

The launch puts OpenAI in direct competition with dominant browsers like Google Chrome and Microsoft Edge, which have already begun integrating AI features. This challenge comes a year after Google was declared an illegal monopolist in online search. Still, Pat Moorhead, CEO and chief analyst at Moor Insights & Strategy, expressed to the BBC his doubts that Atlas will pose a serious threat, saying that “mainstream, beginner, and corporate users will likely wait for their preferred browsers to offer this capability.”
At OpenAI’s DevDay earlier this month, CEO Sam Altman revealed that ChatGPT now has 800 million weekly active users, up from 400 million in February, according to research firm Demandsage. Following that, the company has unveiled a range of initiatives aimed at directing users toward its online services, including partnerships with e-commerce platforms such as Etsy and Shopify, as well as travel booking sites like Expedia and Booking.com.
