ChatGPT Atlas - The browser with ChatGPT built in

With Atlas, ChatGPT can come with you anywhere across the web—helping you in the window right where you are, understanding what you’re trying to do, and completing tasks for you, all without copying and pasting or leaving the page.

The Four Horsemen of the AI Browser Apocalypse are now here: Perplexity Comet, @Dia Browser, @Microsoft Copilot, and yes, @Google Chrome with AI (runners up: Brave's Leo and @Opera Neon).

Which will win? What do you think?

According to the Atlas Browser Core Experience Design document, these are the core design principles of Atlas:

Design Principles

  • Conversational Interface - Atlas should offer a chat-driven Ul where users express intent rather than navigate menus. Al will interpret commands like "summarize this article" or "schedule a meeting next Friday" and perform the tasks.

  • Agentic Task Execution - The browser should automate multi-step workflows (e.g., filling forms, booking appointments) while keeping the user in control. Examples from Comet show Al agents handling booking or email summarization tasks.

  • Semantic & Structured Web - Because Al agents rely on machine-readable content, Atlas should encourage and leverage semantically rich pages (HTML5 tags, ARIA roles, Schema.org markup) to parse and act upon information effectively.

  • Minimalist Ul - Al-native browsers tend toward clean, distraction-free interfaces because Al handles navigation and decision making. Atlas should prioritise clarity, speed and direct access to core actions over decorative elements.

  • Privacy & Transparency - Al browsers must be explicit about what data they use. Competitive analysis shows different offerings balance access and subscription models; Brave Leo emphasises privacy, while some features require subscriptions (research.aimultiple.com). Atlas should give users fine-grained control over data access and make privacy policies clear.

Brave's Leo  @chrismessina seems like most people (including me) don't actually switch browsers

@chrismessina Google Chrome still benefits from being the default for many, and that market share is hard to beat. Dia is incredible, though the recent acquisition leaves its long-term direction up in the air. Perplexity’s Comet has strong buzz, but the security questions and actual user adoption are still TBD. Copilot feels like it was pushed cause MS needed something out there, I’ve used it twice, then deleted it, found it far inferior to Dia. OpenAI, on the other hand, has the halo effect of ChatGPT. If they bake that seamlessly into the browser, it could see massive adoption fast.

@chrismessina  @mogabr I wonder if there is a security danger as well though. Atlas is supposed to remember everything from agents as well as recent questions/searches. Could be a real security problem as well. This may be the next big thing, securing LLMs on the client side, maybe sandbox these new browsers.

@chrismessina I'm a Chrome user and didn't jump on the Perplexity Comet's train. But I'm very much excited to use ChatGPT's Atlas.

It’s fascinating to see two browser-based AI agents, @Director and Chatgpt Atlas launching head-to-head on the same day. (Yeah, I know — Atlas is way more than just browser agents, but who doesn’t love trying new features first?)

Out of curiosity, I grabbed the sample prompts from Director’s homepage — assuming they all work there — and tested whether Atlas could do the same:

  • Retrieve the California Statement of Information for Browserbase and confirm good standing: ✅

  • File a DMCA takedown request: ✅

  • Find the average gas price from San Francisco to Los Angeles: 🚧 Google Maps initially blocked Atlas from fetching route data without signing in, but once I re-ran in agent mode after signing in, it successfully found gas prices along the route and organized them into a table

Overall, I was really impressed to see how far browser automation is going — can’t wait to see what both teams build next.

👋 hey@shihangw! Product lead for @Director here.

We're excited for Atlas and a new age of consumer browsers. Over at Browserbase, we're obsessed with automating business workflows at scale — compliance, operations, licensing, submission, etc. We care about reliability when running stuff thousands of times, that's why Director outputs repeatable code that you deploy directly on Browserbase.

I'm stoked for a world where beautiful products like Atlas accelerate our daily work, while powerful infrastructure like Browserbase run critical workflows at scale.

Honestly not sure what to think about this.


We know about the collection of data, merging all our history, bookmarks and passwords to a new browser. The risk of prompt injections like the ones that happened to Perplexity Comet.

Okay, some features are super interesting, and there is a lot that you can do from what I tried, and yeah it's powerfull. But this could had just been another Chrome extension and be fine.

Chris Messina

@seantiffonnet you can't get the user's clickstream and new-tab search data if you're "just an extension". From a business perspective, OpenAI needs that data to fulfill its mission and Google is squatting on it with the way extensions are implemented.

Attention to design detail is chefs kiss. When we spend 80% of their day staring at our browser, it's refreshing to see craftsmanship done beautifully. Just look at those control + tab animations 😍

It has been 2 weeks after announcement and still only for MacOs !!!

@mohamed_abdellatif I can’t even use it on my Mac — mine’s Intel, not Apple Silicon

I wonder if people will actually switch browsers or just use AI inside the ones they already have.

Congrats on the launch. OpenAI's APIs feel like a great backbone for an AI-native browser like Atlas. Love the focus on conversational UI, agentic tasks, semantic web, minimal UI, and privacy. How will you keep users in control during multi-step automations?

James

Try it one month ago. Find it kind of useless. Is it better now?

James

Why polish the product better before publish it?

I used Atlas for a repetitive, manual task on a large Excel file. The process was slower than expected and required frequent supervision and restarts. For now, performing the task manually remains faster and more efficient. I hope future updates will make Atlas faster, more autonomous, and better suited for handling large-scale repetitive operations.
