OpenAI has unveiled the ChatGPT Atlas web browser with a built-in chatbot. So far, the program is only available on macOS devices.

The new web browser from OpenAI is designed to combine web surfing with AI capabilities. It is based on the ChatGPT chatbot, and the program itself is based on the Chromium engine.

It is assumed that the user will be able to interact with the AI on any page without closing the tab. ChatGPT will memorize the context and then play it back in the conversation.

The company says the user will retain full control over the amount of data provided to the chatbot. However, working with context “makes it faster and more efficient.”

It also claims the ability to “shift” some of the user’s functions to the AI. This can be search and analysis, event planning and appointment scheduling. These functions are available in Agent Mode, which is already available in evaluation mode for Plus, Pro and Business subscriptions.

At the release stage, the browser is available on macOS for Free, Plus, Pro and Go users. Users on Business, Enterprise and Edu plans can test the program in beta, subject to administrator permission.

A release date on Windows, iOS and Android has not been specified.

The browser is not directly opposed to Google’s Chrome, but could still have an impact on the distribution of market shares in the sector. As an example, shares of Alphabet, Google’s parent company, fell 2.4% (Class A) and 2.2% (Class C) on the back of the browser’s release.

According to StatCounter Global Stats, Google’s browser market share reached 71.86% at the end of September 2025.

Also, note that OpenAI has previously expressed its willingness to buy Chrome from Google.

In addition, the browser has already raised criticism and concerns due to the built-in mechanism for collecting personal data, albeit disabled by default. In particular, the team at Brave, a browser with integrated cryptocurrency features, highlighted Comet as an example of global vulnerabilities in software with built-in AI features.

Comet is a development from Perplexity, which reached a $25 billion valuation after closing its latest investment round.

Privacy issues were also pointed out by Simon Willison, founder of the Datasette project. His review of the browser shows that it, like other programs in this category, is vulnerable to so-called attacks with hidden instructions.
