ChatGPT Atlas launches: AI-powered browser with agent mode, memory controls, and a macOS-first rollout
ChatGPT Atlas

OpenAI has unveiled ChatGPT Atlas, a Chromium-based web browser with ChatGPT built in. Atlas puts a live ChatGPT sidebar next to any website and introduces a new agent mode that can perform tasks on the open web—researching trips, comparison shopping, editing docs in-page, and more. The launch went live on Tuesday, October 21, with global availability on macOS first and Windows/iOS/Android to follow.

What ChatGPT Atlas does differently

  • Side-by-side browsing: A split view shows the webpage and a ChatGPT panel at once. Ask for summaries, definitions, comparisons, code explanations, or data extraction without leaving the page.

  • In-line editing: Highlight text on a site or in a web app and prompt ChatGPT to rewrite, condense, translate, or format—changes preview in context.

  • Agent mode (preview): For Plus/Pro/Business tiers, Atlas can take actions on the web on your behalf—navigating pages, filling forms, booking or reserving, collecting citations, and exporting results. It runs step-by-step so you can pause or adjust.

  • Memory options: Atlas can remember preferences (tone, citation style, company details) to personalize help across sites. Browser memories are opt-in and can be inspected or cleared anytime.

  • Privacy by default: Users are opted out of having Atlas browsing data used to train models. Granular toggles let you block site-specific memory or disable the sidebar on sensitive domains.

  • Performance focus: Built on Chromium, Atlas supports modern extensions, dev tools, and web standards, with hardware acceleration tuned for Apple silicon.

Availability, tiers, and system requirements

  • Platforms: macOS first (Apple silicon; macOS 12 Monterey or later). Windows, iOS, and Android are on the roadmap.

  • Who can use it: Free, Plus, Pro, and Go accounts get the core browser/side panel. Agent mode is available to Plus/Pro and in beta for Business/Enterprise customers.

  • Enterprise notes: Business/Enterprise pilots include admin controls, policy enforcement, and guidance for low-risk trials (e.g., disabling memories by default, domain allowlists).

How it changes everyday browsing

  • Research: Open multiple sources in tabs while the sidebar builds a live brief, pulls out dates and figures, and tracks what you’ve already read.

  • Shopping: Ask for side-by-side feature comparisons, spec tables, and total cost calculations pulled from carts or listings.

  • Docs & dashboards: Use in-line prompts to clean up writing in CMS tools, summarize long PRDs, or annotate dashboards with plain-language explanations of charts.

  • Developers: Explain unfamiliar APIs, diff code in Git web UIs, or generate test cases and curl snippets without leaving the repo page.

  • Students & analysts: Extract structured data (names, amounts, deadlines) from PDFs and pages into tables or CSVs.

Security and safety: what to know on day one

Atlas brings agentic automation into the browser, which raises the stakes on prompt injection and malicious pages that try to hijack instructions. Practical tips:

  • Watch the agent steps: Keep the “show actions” view visible; pause if it starts following unexpected links or pasting sensitive info.

  • Use site rules: Disable agent mode or memories on finance, HR, and admin portals; rely on manual mode for sensitive workflows.

  • Least-data principle: Redact tokens/keys and use temporary credentials for testing automations.

  • Extension hygiene: Uninstall unused extensions and review permissions; Atlas supports the same best practices as other Chromium browsers.

How Atlas fits into the browser landscape

Atlas lands in a rapidly forming category of AI-native browsers. The differentiator is deep ChatGPT integration—a conversational panel everywhere, plus an actionable agent that can operate across tabs like a tireless assistant. For users already paying for ChatGPT, Atlas compresses what used to be a copy-paste loop into a single, continuous workspace.

Quick start guide

  1. Install on macOS and sign in with your ChatGPT account.

  2. Import bookmarks, passwords, and history from your current browser.

  3. Pin the sidebar (⌘⇧A) and try: “Summarize this page in 5 bullets and extract dates.”

  4. Test agent mode on a low-stakes task: “Find three refundable hotels near the conference venue next month, under $250/night, and draft an email with the options.”

  5. Set privacy defaults: Turn off memories globally; re-enable selectively for non-sensitive sites.

FAQ: ChatGPT Atlas

Is Atlas replacing my current browser?
No. It can be your default browser, but it’s designed to coexist—import data and test workflows before switching.

Does it support Chrome extensions?
Yes, Atlas is Chromium-based, so most extensions and dev tools work as expected.

Can I use it at work?
Business/Enterprise pilots are live. Admins can enforce policies, disable memories, and manage updates.

How much does agent mode cost?
Agent mode is included with Plus/Pro and in beta for Business; Free/Go users have the sidebar features without automation.

What about data security?
Browsing data is not used for training by default. You can block memories by site, clear them anytime, and restrict agent mode to specific domains.


Bottom line: ChatGPT Atlas turns the browser into an always-on copilot, pairing conversational understanding with the ability to act on the web. If you already rely on ChatGPT for research or writing, Atlas compresses the workflow into a single window—fast, flexible, and, with the right safeguards, ready for real work.
