Atlas

ChatGPT Atlas is an AI-driven web browser launched by OpenAI in October 2025. Built on the open-source Chromium project, it integrates ChatGPT deeply into the entire browsing experience. The browser aims to change how users interact with the web through an AI assistant, providing instant answers, smart suggestions, and task automation.

Key Features

• AI sidebar chat: Open a ChatGPT sidebar in any window to summarize page content, compare products, and analyze data without leaving the current page
• Browser memory: Optionally remembers pages you visit, tasks in progress, or ideas you are exploring, surfacing relevant information when needed
• Agent mode: ChatGPT can interact with websites autonomously to complete tasks from start to finish, such as researching and booking travel (exclusive to Plus, Pro, and Business users)
• Inline writing assistance: Highlight text in an email, calendar invite, or document and get AI rewrite and optimization suggestions in one click
• Smart search: Supports multiple search modes including text, images, videos, and news articles

Use Cases In daily work, users can use the sidebar to quickly summarize long research articles or technical documents; while shopping online, the AI helps compare specs and reviews across multiple products; when writing emails or reports, real-time writing suggestions and language polish appear right in the input box, with no copy-pasting into other tools.

Unique Advantages As the first deeply AI-integrated browser launched by a major AI company, Atlas's core advantage is that ChatGPT blends seamlessly into the browsing flow rather than existing as a standalone plugin or extension. The browser supports Chrome extensions and is currently available on macOS, with Windows, iOS, and Android versions coming soon. Users keep full control over privacy settings, including choosing which sites ChatGPT is allowed to view, clearing browsing history, and managing stored memories.
