Welcome to Atlas
In October 2025, OpenAI unveiled ChatGPT Atlas—not just another web browser, but a radical rethinking of how humans interact with the internet. Atlas places artificial intelligence at the very core of browsing, creating an experience where AI understanding and human intention merge seamlessly.
This comprehensive guide explores Atlas from every angle: its revolutionary features, practical setup instructions, advanced usage techniques, and answers to your most pressing questions. Whether you're evaluating Atlas as your next browser or seeking to unlock its full potential, you'll find everything you need here.
Understanding Atlas
ChatGPT Atlas represents a fundamental shift in browser design philosophy. Traditional browsers treat AI as a plugin or sidebar feature—something you add on when needed. Atlas inverts this relationship: ChatGPT is the foundation, and traditional browsing features are built around it.
Context-Aware Intelligence
Atlas understands what you're viewing and can assist without you copying text or leaving the page. Ask questions about any content on screen and receive instant, relevant answers.
Autonomous Agent
Agent mode empowers ChatGPT to perform tasks on your behalf—navigating sites, filling forms, researching across multiple sources, and completing complex workflows automatically.
Persistent Memory
Browser memories allow Atlas to remember important context from your browsing sessions, enabling personalized assistance and intelligent suggestions based on your history.
Unified Interface
The new tab page merges search, chat, and results into one cohesive experience. No more juggling between search engines and AI assistants.
Privacy Controls
Granular control over what ChatGPT can access. Toggle visibility per page, manage memories, and choose exactly what data to share.
Full-Featured Browser
All modern browser essentials included: bookmarks, passwords, tabs, downloads, and developer tools—plus AI capabilities layered throughout.
System Requirements
Hardware & Software

Our Assessment
After extensive testing, ChatGPT Atlas emerges as a bold experiment in browser evolution. It's not without limitations—agent mode remains in preview and occasionally makes errors, the extension ecosystem is nascent, and some workflows require adaptation. However, for users deeply embedded in the ChatGPT ecosystem who spend significant time researching, learning, or working online, Atlas offers a genuinely superior experience.

If you're a power user of ChatGPT and your work involves research, content creation, or extensive web interaction, Atlas represents a meaningful step forward in how AI can enhance browsing.
