Review Summary

Copy Link

Comet Browser was one of the first agentic browsers to release, meaning that you can not only talk to the baked in Assistant (Perplexity), but you can have it interact with your tabs, emails, calendar, and even navigate the web for you (as if an assistant took over your screen). It's currently the only totally free agentic browser (at least for now). And while it's not as good as Dia or ChatGPT Atlas, it is the only one that gives truly free access to agent mode.

This makes Comet good specifically for researching and shopping.

Best AI Browser? Comet vs ChatGPT Atlas vs Dia (Honest Review)

What is Comet Browser?

Copy Link

Comet Browser is an AI-native browser created by the team over at Perplexity, who has been shaking up the search space. The main differentiator with Comet is that their Comet Assistant is at the core, which gives us a taste of what's coming with the coined term "Agentic Browsing". All that really means is that the assistant not only searches with more context and interacts with your tabs, but it actually clicks around the web for you.

Out of all the AI browsers, I trust Comet the most for deep research where I actually need factual information. The reason is because Comet is the most connected to the internet and it gives you clear citations of where it gets it's information from (while ChatGPT can make things up sometimes). So if I am looking for facts, data, sources, I always open up Comet.

Not to mention, Comet's Android Browser is good in a pinch (although not my main mobile browser). It comes in handy specially when shopping online because I can actually use the AI Assistant and it can look for promo codes (so I can finally shop on my phone), available on iOS and Android.

Comet Browser’s agent mode is completely free, unlike other AI browsers where you need to be on a paid plan to unlock agent capabilities so even if it doesn't become your one and only browser, it's incredibly handy to have on your devices.

Who is Comet Browser For?

Copy Link

If you’re the kind of person who jumped on Perplexity before it blew up, you’re the target market. Comet will likely appeal to:

Power users who feel like they're constantly jumping between Perplexity, ChatGPT, and their browser
Those who have been waiting for AI to actually "do things for them" as if they were an assistant or employee
Anyone burned out by Chrome and bored by Safari

Basically, early adopters, who are fine with a product being rough around the edges, but power-user features that not many people have seen before.

Key Features

Comet Browser Assistant

Copy Link

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.

Examples of what Perplexity Assistant can do

Comet Voice Assistant

Copy Link

If you've ever used ChatGPT's voice mode, imagine that, but being able to dive into a conversation with the website you're on, tabs you have open, and the wider internet. Searching for deals, what the main points are of a YouTube video, or want it to book a reservation for you? All of that is possible with the assistant on the sidebar:

Talk to the webpage you're on or broader internet

While this is super promising, it can't yet seem to take action on the page that I'm on just yet. While they've shown some demos of this in action on X, it's not quite functional to that degree yet.

That said, being able to talk to a page is away more enjoyable experience than reading it. Heck, you might be chatting with this review right now for all I know. It feels like the future.

Email and Calendar Integration

Copy Link

What's an assistant (and now browser) without connection to your email and calendar? If you want it to book a flight for you, doesn't it need to know what your availability is?

That's where it asks you for full read/write access to your Gmail and Google Calendar, and you can ask the browser questions about your email, upcoming events, and more.

This one feels like Chrome should have had this for ages, but with Google's upcoming Gemini integration with Chrome, we're likely to see something similar.

Pricing

Final Verdict

Copy Link

Is Comet Browser worth it? The truth of the matter is we find ourselves using Dia and ChatGPT Atlas much more often.
