Comet is the best ChatGPT Atlas alternative in October 2026: a free AI browser with an assistant that reads your tabs and acts on websites, on Mac, Windows, iOS and Android. Stay with OpenAI through ChatGPT Work in the desktop app, or keep Chrome and add Gemini. Atlas itself stopped working on August 9, 2026.

Why people are leaving Atlas

There is no choice to make about staying. OpenAI announced on July 9, 2026 that it was deprecating Atlas "as we bring browser-based agentic capabilities into ChatGPT and Codex," and Atlas stopped working on August 9. Bookmarks, open tabs, history and cookies did not transfer automatically. If you are reading this before cleaning up, check your Downloads folder for an exported bookmarks HTML file and import it into your new browser.

What former users usually want back is one of three things:

  • An assistant inside the browser. Comet, Gemini in Chrome, Dia and Opera Neon all do this.
  • The agent that clicks and types for you. ChatGPT Work, Comet, Gemini auto browse, Opera Neon Do and Manus Browser Operator.
  • ChatGPT itself. Only ChatGPT Work keeps your OpenAI memory, plugins and history in one place.

Our picks, in detail

#1 Best overall Atlas replacement

Comet

Perplexity's free Chromium based AI browser with Comet Assistant, which answers questions about your tabs and carries out tasks on websites.

4.2
Price
$0
Platforms
Mac, Windows, iOS, Android
Agent mode
Comet Assistant acts on sites and runs tasks in parallel tabs
Privacy controls
Browsing data stored locally by default, per site blocking, Incognito stops Assistant indexing

Comet is the closest thing to Atlas still running: a Chromium browser with an assistant in every tab that reads your pages and acts on websites. It is free, and unlike Atlas it runs on Mac, Windows, iOS and Android, so former Atlas users finally get the Windows and phone versions OpenAI never shipped.

Pros

  • Free on desktop and mobile, with no account required to start
  • Chromium base supports most Chrome Web Store extensions
  • Assistant can use any tab you mention with @ and run several errands in parallel
  • Settings let you block Comet Assistant from specific sites such as your bank

Cons

  • Brave disclosed indirect prompt injection flaws in August and October 2025, and said the first fix was incomplete
  • Advanced Assistant models listed on the $167 per month Max plan only
  • Pro and Max show annual prices only on the pricing page
  • Linux is not officially supported

Skip it if prompt injection worries you most; Brave published two Comet attacks in 2025.

4.8 out of 5 from 7,807 reviews on App Store (October 2026).

#2 Best for staying with OpenAI

ChatGPT agent

OpenAI's agent inside ChatGPT, now delivered as ChatGPT Work, that researches, uses a browser and your connected apps, and produces finished documents.

4.1
Price
$20 per month
Platforms
Web, iOS, Android, ChatGPT desktop app for macOS and Windows
Agent mode
ChatGPT Work plus agent mode in Chat; virtual browser and built in desktop browser
Privacy controls
Takeover mode hides logins from screenshots, training opt out, Lockdown Mode, no training on business data

OpenAI moved Atlas's agent into ChatGPT Work, which has a built in multi tab browser in the ChatGPT desktop app and can sign in to sites on Plus. Your ChatGPT chats, memory and plugins carry over, and Plus is the same $20 per month that unlocked Atlas agent mode.

Pros

  • Produces finished files and interactive Sites, not just answers
  • 1,400+ plugins plus a built in browser that can sign in to sites with your approval
  • Event triggered tasks from Gmail, Slack and GitHub on Plus and above
  • Takeover mode keeps passwords out of agent screenshots

Cons

  • Usage is a shared Work and Codex pool described as ranges, not fixed task counts
  • Strongest model access and Ultrafast sit on $100 to $500 Pro plans
  • OpenAI says safeguards will not stop every prompt injection attack
  • Event triggered tasks are not available on Free or Go

Skip it if you want an assistant inside your everyday browser rather than a separate app.

4.8 out of 5 from 11,431,550 reviews on App Store (ChatGPT app) (October 2026).

#3 Best if you do not want a new browser

Gemini in Chrome

Google's Gemini assistant built into Chrome, free for signed in users, with auto browse for multi step tasks on Google AI Pro and Ultra.

4.0
Price
$0
Platforms
Chrome on Windows, Mac and Chromebook Plus; Android and iOS Chrome with fewer features
Agent mode
Auto browse: plans, then shops, books and fills forms; desktop only
Privacy controls
Runs only when you open it, tab sharing controls, Gemini Apps Activity settings, not in Incognito

Most Atlas users imported their data from Chrome in the first place. Gemini in Chrome gives free chat across up to 10 tabs, and auto browse handles shopping and bookings on Google AI Pro at $19.99 per month, with a plan review step before it acts.

Pros

  • No new browser to install; it is part of Chrome on desktop
  • Chat side is free and can use up to 10 open tabs
  • Auto browse shows its plan before it starts and asks you to take over payments, terms and account creation
  • Uses Google Password Manager to sign in without sharing passwords with Gemini

Cons

  • Auto browse needs a $19.99 per month plan and is capped at 20 tasks a day on Pro
  • Google says you are responsible for auto browse mistakes, including purchases
  • Not available in Incognito or on school accounts
  • Page content and URLs from shared tabs go to Gemini

Skip it if you need auto browse in a language other than English or on iPhone.

#4 Best for work and security

Dia

The Browser Company's AI browser for work, with chat across your tabs and tools, a Morning Brief and reports, now part of Atlassian.

3.9
Price
$10 per month
Platforms
macOS and Windows
Agent mode
Limited by design: acts only on context you approve and cannot navigate to other sites on its own
Privacy controls
Local storage by default, end to end encrypted sync, content data sharing opt out, SOC 2 Type II

Dia publishes the strictest prompt injection rules of any AI browser and holds a SOC 2 Type II report, which answers the security worries that followed Atlas. It pulls context from Slack, Notion and Google Workspace; AI plans start at $10 per month on the plan card ($20 in its FAQ).

Pros

  • Published prompt injection controls: no auto opening of AI generated links, no agent navigation to other sites, drafts shown before anything is sent
  • SOC 2 Type II examination for calendar year 2025
  • AI partners are contractually barred from retaining or training on your data
  • Free tier is a full browser with ad blocking and encrypted sync

Cons

  • AI features need a paid plan; the pricing page shows two different prices for Better Answers
  • Morning Brief, reports and decks sit on the $100 per month Better Days plan
  • Not HIPAA compliant and no BAA, per its security FAQ
  • No mobile browser

Skip it if you want an agent that books and buys across sites; Dia's agent cannot navigate on its own.

#5 Best for model choice

Opera Neon

Opera's agentic browser with Neon Chat, the Neon Do browser agent, three research agents and an MCP server for outside agents, for $19.90 a month.

3.8
Price
$19.90 per month
Platforms
macOS and Windows
Agent mode
Neon Do acts in your local browser session, plus scheduled tasks and research agents
Privacy controls
No training on user data, credentials and payments stay on device, chats kept 365 days

If you liked Atlas but wanted more than OpenAI's models, Neon Chat offers GPT, Claude, Gemini, Grok, DeepSeek and Qwen3, and Neon Do acts in your logged in tabs. It costs $19.90 per month.

Pros

  • Model choice in Neon Chat, including GPT, Claude, Gemini, Grok, DeepSeek and Qwen3
  • Neon acts as an MCP server so outside tools like Claude Code can work in your live session, read only by default
  • Opera says it does not train on user data and its model providers are barred from it
  • Built in ad blocking and VPN from the core Opera browser

Cons

  • $19.90 per month with no annual discount listed
  • Brave found a hidden HTML prompt injection in Neon in October 2025 (fixed October 21, 2025)
  • Chats and agent workflows stay on Opera's servers for 365 days
  • No mobile version yet

Skip it if you want a free browser or a phone app.

#6 Best for turning browsing into documents

Genspark

An AI workspace built around Super Agent, which browses, codes and builds slides, sheets and docs, plus an AI browser, Chrome extension and phone calling agent.

3.7
Price
$24.99 per month
Platforms
Web, iOS, Android, Chrome extension, Genspark AI Browser
Agent mode
Super Agent with its own sandboxed browser and filesystem; extension automates your tabs
Privacy controls
Team and Enterprise opted out of training automatically; extension reads a page only when used

Genspark's AI Browser and Chrome extension summarize pages and automate forms, and Super Agent turns research into slides, sheets and docs. Plus is $19.99 per month billed annually with a weekly Free Quota for Standard mode tasks.

Pros

  • Weekly Free Quota on Plus covers Standard mode Super Agent, Slides, Sheets, Docs and Deep Research without spending credits
  • Annual billing saves about 20%
  • Super Agent runs in a sandbox with a real browser and its own filesystem
  • Call for Me places real phone calls and returns a transcript

Cons

  • Pro jumps from $24.99 to $249.99 per month
  • Free credits stop after a lifetime allowance
  • Call for Me costs a flat 500 credits per call
  • Training opt out is automatic only on Team and Enterprise

Skip it if you just want a browser sidebar and no workspace.

4.7 out of 5 from 4,341 reviews on App Store (October 2026).

#7 Best for heavy agent jobs

Manus

A general purpose AI agent that researches, builds websites, slides and apps, and runs browser tasks in the cloud or in your own browser, billed in credits.

3.6
Price
$20 per month
Platforms
Web, iOS, Android, desktop app (Manus Studio)
Agent mode
Agent Mode with Cloud Browser, Browser Operator in your own browser, Wide Research
Privacy controls
Training opt out on Team; Browser Operator needs per session authorization

Manus's Browser Operator extension uses your existing logins like Atlas agent mode did, and paid plans run 20 tasks at once. The free plan refreshes 300 credits every day.

Pros

  • Wide Research deploys many agents in parallel, each with its own context
  • 20 concurrent tasks and 20 scheduled automations on paid plans
  • Choice of a sandboxed Cloud Browser or the Browser Operator extension in your own browser
  • Free plan refreshes 300 credits every day

Cons

  • Credit use depends on task complexity, so costs are hard to predict
  • Trustpilot score of 1.2 from 218 reviews, with complaints about credit burn, refunds and support
  • Training opt out is listed only on the Team plan
  • Some users' data was deleted in August 2026 as part of the Meta unwind

Skip it if you want predictable costs; credit burn varies by task.

4.7 out of 5 from 39,344 reviews on App Store (October 2026).

How to choose

Decide where you want the agent to live. If you want it inside the browser you use all day, pick Comet, Gemini in Chrome, Dia or Neon. If you are fine opening a separate app for bigger jobs, ChatGPT Work, Genspark or Manus give you more output than any browser sidebar.

Check platforms. Atlas was macOS only. Comet is the only pick here with a full browser on iOS and Android as well as Mac and Windows. Dia and Neon are desktop only.

Match the price to the agent, not the browser. The browsers are mostly free. The agents cost money: Google AI Pro is $19.99, Opera Neon $19.90 and ChatGPT Plus $20 per month. Comet's assistant is free, and Perplexity reserves its advanced Assistant models for Max at $167 per month billed annually.

Security after Atlas

OpenAI was candid while Atlas ran: agents "are susceptible to hidden malicious instructions" and its safeguards "will not stop every attack." In December 2025 Gartner advised organizations to block AI browsers for now, naming Atlas and Comet, according to The Register. That advice applies to every replacement on this list. Practical rules: block the agent from banking and health sites (Comet and Gemini both have controls), prefer logged out or sandboxed browsing for research (Manus Cloud Browser, ChatGPT Work's cloud browser), and give specific instructions instead of "handle my inbox." Dia is the only pick that documents limits on its own agent's movement.

What it costs

Pick Cheapest way to get the agent
Comet $0
Gemini in Chrome $19.99 per month (Google AI Pro)
Opera Neon $19.90 per month
ChatGPT Work $20 per month (Plus)
Dia $10 per month on the plan card ($20 in the FAQ)
Genspark $19.99 per month billed annually
Manus $20 per month, or free with 300 daily credits

How we picked

We ranked on published facts as of October 2026: price for the agent, platforms, what the agent can do, documented privacy and security controls, and verified ratings where they exist. We do not claim to have used these products; every figure comes from vendor pricing pages, help centers, app stores and security research linked in the sources.

Frequently asked questions

What replaced ChatGPT Atlas?

OpenAI points users to the ChatGPT desktop app, where ChatGPT Work has a built in browser, and to the ChatGPT browser extension for Chrome, Edge, Brave, Opera and Vivaldi.

What is the best free alternative to Atlas?

Comet. It is free with an assistant that acts on sites. Gemini in Chrome's chat side is also free, though its agent needs Google AI Pro.

Is there an Atlas alternative for Windows?

Yes. Comet, Dia, Opera Neon and Gemini in Chrome all run on Windows. Atlas never shipped on Windows.

Can I import my Atlas bookmarks into another browser?

Only from a bookmarks HTML file you exported before the shutdown. OpenAI's help article walks through importing it into Chrome, and most Chromium browsers including Comet and Dia accept the same file.

Which Atlas alternative is safest?

Dia, on published facts. It blocks its agent from navigating to other sites, will not open AI generated links, shows drafts before inserting anything and holds a SOC 2 Type II report.

Do I lose my ChatGPT history if I leave Atlas?

No. OpenAI says your ChatGPT conversations are separate from Atlas browser data and remain in ChatGPT, subject to your plan.
