ChatGPT Atlas Is Gone: 6 Alternatives Compared (2026)

ChatGPT Atlas shutdown: what happened?

• 21 October 2025: OpenAI launched ChatGPT Atlas “worldwide on macOS”, saying that experiences for “Windows, iOS, and Android are coming soon.”
• Summer 2026: OpenAI retired Atlas. Its notice read: “Atlas is scheduled to stop working on August 9, 2026… After that date, Atlas may no longer open, browse, or support browser-based agentic workflows” (OpenAI notice, as posted on the OpenAI Community forum). OpenAI’s help page, ChatGPT Atlas retirement, now says Atlas “has been retired and no longer receives updates.”
• What replaced it: According to 9to5Mac, OpenAI moved browsing into the ChatGPT desktop app. OpenAI’s current retirement page doesn’t name a replacement.

OpenAI confirms that your ChatGPT conversations are separate from Atlas browser data, and you can keep using them in ChatGPT, “subject to your plan, workspace settings, and account access.” Atlas browser memories are separate from ChatGPT memories too, and deleting your ChatGPT chats doesn’t delete Atlas data.

Atlas bookmarks after the shutdown: import and recovery

OpenAI’s notice asked users to “export or save any important Atlas data, including bookmarks and pages you want to keep” before 9 August. OpenAI’s retirement page confirms that bookmarks, open tabs and browsing history don’t transfer automatically. What carries over is whatever you exported, such as a bookmarks HTML file.

If you didn’t export in time: OpenAI says to contact its support team if you can no longer reach information you need, but warns that “Recovery is not guaranteed.” If you still need data saved in Atlas, contact support before uninstalling Atlas or deleting its local data (OpenAI Help).

If you have an exported HTML file, you can import it into another browser. “You do not need to open Atlas,” OpenAI says.

• Chrome: More (⋮) → Bookmarks and lists → Import bookmarks and settings → Choose file → select your HTML file → Open → Done (Google Chrome Help).
• Microsoft Edge: Settings → Profiles → Import browser data → next to “Import browser data now”, select Import → under “Import from”, choose Favorites or bookmarks HTML file → Choose file → select the file → Open → Done. Imported favorites appear in a folder on the Favorites bar, which may be called “Imported” (Microsoft Support).
• Other browsers (Comet, Dia, Opera Neon): most browsers have a similar import option in their settings. Check the browser’s own help pages.
• Saved passwords: if you exported a password CSV file from Atlas, OpenAI points to Google Password Manager’s import instructions. Delete the CSV afterwards, because it contains readable passwords. Otherwise, use each website’s account recovery.

6 ChatGPT Atlas alternatives compared

1. ChatGPT desktop app + ChatGPT Chrome extension: the official route

Best for: people who used Atlas mainly for ChatGPT.

The ChatGPT desktop app now includes a built-in browser, and OpenAI also offers a ChatGPT extension for Chrome. OpenAI’s documentation for the Windows app lists “the built-in browser” among its features. 9to5Mac describes the desktop browser as supporting tabs, downloads, logins, autofill, passwords and extensions, but says it “isn’t exactly a browser-first experience.”

OpenAI’s help page says the built-in browser is “available in the ChatGPT desktop app on macOS and Windows”, uses its own browser state, and that “Available features may depend on your plan and workspace settings.” You open it from a chat in Work or Codex (Command+Shift+B on macOS, Ctrl+Shift+B on Windows). When a task needs your existing Chrome profile, signed-in sessions, open tabs or extensions, OpenAI points you to the ChatGPT browser extension instead, and “You do not need to install the ChatGPT desktop app to use the extension.” OpenAI’s own advice: “Treat website content as untrusted.”

Caveats: This isn’t a full standalone browser. On 27 October 2026, ChatGPT’s pricing page listed Free ($0), Go ($8/month), Plus ($20/month) and Pro (from $100/month). It described ChatGPT Work access as “limited” on desktop for Free and “expanded” on desktop, web and mobile for Plus. Prices can vary by country.

2. Perplexity Comet: the closest standalone AI browser

Best for: research, comparing sources and summarizing pages, on any device.

Perplexity’s Comet page lists it as “Available for Mac, Windows, iOS, and Android.” Perplexity doesn’t list a Linux version. Its Comet page doesn’t list prices, so check Perplexity’s site for current plans and any limits on agent use.

Security record: Comet has had more published security research than any other AI browser, including work by Brave, LayerX and Zenity. Some issues were fixed. In LayerX’s June 2026 BioShocking table, Comet’s report was listed as “closed / ignored”. Read Are AI browsers safe? before letting its agent act in logged-in accounts.

3. Chrome with Gemini (auto browse): best if you already use Google

Best for: Google AI Pro or Ultra subscribers who want an agent without switching browsers.

Gemini in Chrome isn’t a separate browser; it’s built into Chrome. Its agent feature, auto browse, launched on 28 January 2026 for Google AI Pro and Ultra subscribers in the US, on Windows, macOS and Chromebook Plus (Google). It came to Android in the US in August 2026 (Google).

Google’s Chrome Help page says you must be 18 or over, use an English device language, and that AI Pro allows up to 20 requests a day and Ultra up to 200. Google’s pages differ on regions. Chrome Help says the US, and Google’s Google One help page lists “India and the US.” Check Chrome Help for your country.

Google says auto browse is “designed to pause and explicitly ask for your confirmation” before sensitive actions such as purchases or social posts.

Caveats: Paid plan required. Google doesn’t list Linux.

4. Microsoft Edge with Copilot: a strong pick on Windows

Best for: Windows users who want AI help in the browser they already have.

On 13 May 2026, Microsoft announced it was “retiring Copilot Mode” and folding its features into standard Edge, including multi-tab context, long-term memory, Vision and Voice on desktop and mobile in Copilot markets (Microsoft Edge Blog). The agent feature, now called Browse with Copilot, is available on Edge desktop for Microsoft 365 Premium subscribers in the US only, with usage limits.

Caveats: The agent is paid and US-only. Other features vary by market.

5. Dia: an AI-first browser, now on Windows too

Best for: people who want a clean, AI-first browser and don’t mind paying for the AI.

Dia comes from The Browser Company, the makers of Arc. Its pricing page lists three plans:

New users get a 14-day trial of Better Days. The pricing page says paid plans are rolling out to new Mac users, and existing users get at least 30 days’ email notice before paid plans apply to them. On Windows, Dia “stays as it is for now.”

Dia for Windows reached version 1.0 on 6 October 2026, and version 1.3.0 (22 October 2026) added sync between Windows and Mac (Dia Windows changelog). No Linux version is listed.

Security: The Browser Company publishes security bulletins for Dia. We didn’t find independent prompt-injection research specific to Dia as of 26 October 2026.

6. Opera Neon: an agent-focused browser on a subscription

Best for: people who want a browser built around agent tasks and are happy to pay.

Opera’s Neon site says you need to subscribe, at $19.90/month, to activate the agent features. Check Opera’s site for supported operating systems.

Security: In October 2025, Brave found that hidden text on a web page could make Neon’s assistant read the user’s email address from their Opera account page and send it to an attacker. Brave reported it on 14 October 2025. Opera fixed it by 21 October 2025, and Brave’s retest indicated it was patched (Brave, 31 Oct 2025).

Also worth knowing

9to5Mac also mentions Aside, plus Anthropic’s options (a Claude extension for Chrome and a sandboxed browser in Claude Code), as Mac alternatives. In LayerX’s June 2026 research, the Claude Chrome extension’s patch was assessed as unsuccessful. See Are AI browsers safe?.

Which Atlas alternative should you choose?

A word on safety before you switch

Every AI browser that can act for you shares the same unsolved weakness: hidden instructions on a web page can hijack the agent. The UK’s NCSC says these attacks “may never be totally mitigated” (NCSC). In LayerX’s June 2026 test of six AI browsers and extensions, Atlas was the only one marked fixed, and it has since been discontinued (LayerX).

Whichever you pick, keep the agent away from your email, bank and password manager. Read the full guide: Are AI browsers safe?

How we compared
