Both agentic browsers are great, Atlas is better if you use ChatGPT as your daily AI chatbot, and Comet is better if you use Perplexity as your primary AI chatbot.
That said, you have restricted AI features in Atlas unless you're a paying user of ChatGPT, so if you're not on a paid account, go with Comet to get more AI features, plus Perplexity also often has free Perplexity deals.
We believe there are better options available in this category, read below to learn what this software does well, and what they could do better. ⤵

Bring ChatGPT with you across the web for instant answers, smarter suggestions, and help with tasks—all with privacy settings you can control.
ChatGPT Atlas is a Chromium-based browser built by OpenAI that feels a lot like Google Chrome, but instead of Google Search, you have the full power of ChatGPT available everywhere you go.
ChatGPT Atlas has an AI agent mode that can navigate the web on your behalf. It has ChatGPT with you everywhere (even highlight some text and tell it how you want to modify it and it'll do it inline right there).
Because it's a browser, you also have the ability to @ mention tabs to pull in added context, and it also has deep memory on what you're searching from day-to-day. Other than that, it's really just ChatGPT in the browser.
Think of ChatGPT Atlas as more of an upgraded UI/UX for the ChatGPT desktop app than that of a full replacement for your primary browser.
If you compare it in that way, then it's a no-brainer to install and use it instead of the ChatGPT desktop app.
For example, clicking on a link mid-chat expands the site to the left-hand-side, with chat sitting on the right. It's just a better user-experience than it popping you out to whatever default browser you have set.
From there you can easily ask additional questions about the site you're on, or even reference other open tabs along with browser history. And depending on how complex of a question you ask, their built-in AI agent mode can even pop in and start navigating and completing tasks for you.
So what is the biggest "Pro" for ChatGPT Atlas? It's that it feels like an upgraded desktop app on all fronts. It just feels "right".
Now this is a browser after all, right? Well, when looking at it as one of the best browsers on the market, it feels like you're using a browser that's still in alpha (not even yet beta).
When comparing it to the other agentic browsers in the space, e.g. Dia and Comet, Comet just feels way more fleshed out and refined in many of the micro interactions, interacting with extensions, bookmarks, you know, all the things that make a browser feel like a browser.
So Comet browser feels more like it's in beta, so a generation or so ahead of Atlas browser.
While Atlas is technically free, the features that you're probably seeing teased all over social media and the marketing videos are actually primarily paid (at least for now).
To unlock their AI agent functionality, you must be on ChatGPT Plus ($20/mo) or higher. The same goes for memory and file recall (prior uploaded documents) as well.
So while Atlas is free, it's a pretty restricted version of it.
This is where we'd recommend also giving Comet a shot, especially if you don't have a paid ChatGPT account already, because many of the AI agent features that Comet also has, are readily available to free users.
Do you use ChatGPT? If yes, absolutely install Atlas browser, and just treat it as more of a replacement for the ChatGPT desktop app.
In-fact, use ChatGPT for work and personal, and have 2 separate accounts? Use Atlas to login to one of them, and the ChatGPT desktop app to login to the other one, and boom! You've now got built-in account switching (sorta).
If you're not a paying user of ChatGPT, then I'd recommend you give Comet browser by Perplexity a shot if you want to experience the AI agent mode and other agentic features without purchasing a paid subscription.
A browser for agentic search by Perplexity.
Comet Browser is an upcoming Browser built by the team behind Perplexity (one of the most promising search-focused AI teams right now).
What they realized is that web browsers are at the core of search, so what if they built a browser that has their AI search at the core? Might sound familiar to The Browser Company's thesis with their new upcoming Dia Browser, but Perplexity is quite a bit larger and has had more success in the search space, taking nearly 2% of global search traffic.
Perplexity has something up their sleeve with Comet though, and it's all around their Assistant.
Comet's built-in assistant is what sets it apart from all the best browsers we've covered. It handles the new table-stakes well, with Perplexity at the core, so all the usual search and research functionality is handled.
It can also interact with open tabs, allowing you to essentially target your search and research to a more specific dataset to what you're looking into. But Dia can do this as well, so it's not particularly standout in a browser.
But what does set it apart is Comet gives us the first actual glance at what this coveted "Agentic Browsing" experience actually is, in a non-technical, actually user-friendly way.
What does this mean? Well it can connect into your calendar and email to tell you about important emails (cool, like Google Assistant, right?), but most impressively it can even navigate the web for you.
I'm saying that you can ask it to do things, and it will actually navigate around the page your on, open new pages when needed, and take action as if it's a human you're asking to do something for you.
With all of that said, moving into the browser space is incredibly difficult, but there is something incredibly interesting about this new wave of AI browsers, and we're totally here for the browser space to finally evolve.
