ChatGPT Atlas

OpenAI released 'Atlas', a Chromium-based browser that integrates ChatGPT directly into the browsing experience.

Power users and professionals who do research-heavy work and want AI assistance inline with their browsing workflow, without switching apps.

Atlas is a Chromium-fork browser with ChatGPT natively embedded — no extension required
AI features available: summarize page, ask about selection, fill forms, side panel chat while browsing
Browsing context (current page content) is automatically injected into ChatGPT conversations
Privacy implications: OpenAI has access to all browsed page content when AI features are active
Competes with browser extensions (Arc, Perplexity, etc.) but offers deeper OS-level integration

Try Atlas for research workflows where you frequently copy-paste content between browser and ChatGPT.
Review OpenAI's data privacy policy for Atlas before using it with sensitive work — page content is shared with OpenAI.
Compare against browser extensions (Arc Max, Perplexity) if you prefer not to switch default browsers.

ChromiumThe open-source browser engine underlying Chrome, Edge, and many other browsers; Atlas is built on top of it.

Side PanelA browser UI element that displays supplementary content (like a chat interface) alongside the main webpage.

Browser IntegrationAI capabilities built natively into the browser, with access to page content, rather than running as a separate app or extension.
