“A Once-in-a-Decade Opportunity,” Says Sam Altman
OpenAI CEO Sam Altman introduced the new browser in an unexpected livestream and X (formerly Twitter) post.
Our new AI-first web browser, ChatGPT Atlas, is here for macOS.
Please send feedback! Availability on other platforms to follow.

Describing the launch during the livestream, Altman said, “We think AI represents a rare, once-a-decade opportunity to rethink what a browser can be. In the same way that, for the previous way people used the internet, the URL bar and the search box were a great analogue, what we’re starting to see is that the chat experience and the web browser can be a quick analogue.”
Altman emphasised that ChatGPT Atlas is not just another browsing tool. Instead, it reimagines how users interact with the web by embedding ChatGPT throughout the browser, enabling users to ask questions, summarise content, or perform tasks directly without switching tabs or copying text between applications.

ChatGPT Atlas – All About OpenAI’s Web Browser
The ChatGPT Atlas browser is built on Chromium just like Google Chrome and Perplexity’s Comet, but it redefines the browsing experience with AI at its core. Instead of a traditional address bar, Atlas offers a search bar where users can either enter a website URL or directly ask questions to ChatGPT.
Each tab also includes a side panel for accessing the chatbot instantly, allowing users to engage with ChatGPT alongside their current page. All search queries are routed through ChatGPT and the new tab interface presents categorised links for web, image, and video results, among others.
One of Atlas’s standout features is context-aware assistance, where ChatGPT understands what users are viewing or doing within the browser. This enables tasks such as summarising articles, drafting emails, or researching topics simply by asking the AI. OpenAI highlights that context-awareness allows users can ask ChatGPT questions like, “Find all the job postings I was looking at last week and create a summary of industry trends so I can prepare for interviews.”
Subscribers to ChatGPT Plus, Pro, or Business plans can unlock more advanced capabilities including multi-step and automated actions, performed directly by ChatGPT on their behalf.
The browser also includes an optional “Browser Memories” feature, giving users the choice to allow ChatGPT to remember key information and provide personalised, smarter suggestions over time. Importantly, this feature is fully controllable, allowing users to decide what the AI can or cannot retain.
ChatGPT Atlas supports inline text editing, letting users highlight any portion of a web page and interact with or modify it using ChatGPT. In addition, robust privacy controls allow users to manage exactly what the AI can access or remember, ensuring a transparent and secure browsing experience.
However, one limitation noted by early reviewers is that ChatGPT Atlas cannot automate in-browser testing on localhost, which some developers see as a missed opportunity for a truly comprehensive AI development tool.
Availability and Future Plans
Currently, ChatGPT Atlas is exclusive to macOS. Atlas is also available in beta for Business and if enabled by their plan administrator, for Enterprise and Edu users.
Meanwhile, OpenAI has begun collecting user feedback to refine the experience before expanding to other platforms. The company has confirmed that Windows, iOS, and Android versions are already in the works and will be released in the coming months.
