OpenAI announced the launch of its Atlas web browser, integrated with ChatGPT, on Tuesday, October 21, 2025. The San Francisco-based company, known for its chatbot with over 800 million users, aims to directly compete with Google Chrome by offering AI-driven searches and interactions. The product debuts on macOS for global users, with expansions to Windows, iOS, and Android planned soon.
Atlas allows ChatGPT to act as a browsing companion, summarizing content and answering queries in real time. Built on the Chromium engine, the browser retains standard features like tabs and bookmarks but adds innovations to attract traffic and boost revenue through digital ads. The company seeks to diversify income sources, as it operates at a loss despite a large free user base.
- Initial support exclusive to Apple laptops, with gradual rollout to other platforms.
- Available for free accounts, but advanced features limited to Plus and Pro subscribers.
- Integration of browsing history for personalized AI responses.
Key Atlas features
The browser includes a ChatGPT sidebar for instant page analysis. Users can select text and edit via AI directly in context.
Ben Goodger, OpenAI engineer and former Chrome developer, highlighted ChatGPT’s centrality to the product. Adam Fry, product lead, emphasized the “sidecar” for seamless interactions.
Agent mode in action
The agent mode performs autonomous tasks, such as filling forms or booking services. During demos, the system navigated sites, explaining steps and allowing manual intervention with control buttons.
Paid subscribers access this full functionality, which uses user history for precise decisions. The feature avoids actions in incognito mode, preserving privacy.
OpenAI positions Atlas as an opportunity to redefine browsers, similar to Chrome’s impact in 2008 against Internet Explorer. Sam Altman described it as a rare chance for innovation in productive browsing.
Expansion and competition
Perplexity launched its Comet browser earlier this year, with billion-dollar offers for Chrome. Google added Gemini to its browser, which holds about 3 billion users.
OpenAI previously expressed interest in acquiring Chrome during a U.S. antitrust case, but the judge rejected the sale, citing AI advancements as a competitive factor.
- Agent mode performs clicks and searches based on history and preferences.
- Browser memory personalizes experiences without compromising sensitive data.
- Support for importing passwords and bookmarks from other browsers.
Development history
Rumors about the project surfaced in July, focusing on AI agents for web automation. The launch follows testimony in federal court regarding Google’s monopoly.
The company integrates tools like Operator for complex tasks, expanding beyond chatbots. Atlas uses Chromium for broad compatibility, easing adoption.
OpenAI plans rapid updates for mobile platforms, aiming to capture users seeking efficiency. The browser responds to the trend of AI in everyday tools, reshaping internet access dynamics.
The company faces financial losses, but Atlas could drive subscriptions and data for model training. Early macOS users report smooth performance in initial tests.
