For years there has been an “accepted” way of using browsers, you open a set of tabs, search, visit websites, add to bookmarks and close the tabs when the intended task is completed. While there has been multiple browsers over the years with various subtle changes (vertical tabs, horizontal tabs, advanced tab management, grouping and various productivity tools), there has not been a drastic change to the way we use browsers.
That is, until recently.
Starting from Perplexity Comet and Dia and most recently, ChatGPT Atlas, there is a new breed of browsers, AI-Browsers, which intend to disrupt the way a typical user use browsers and take the long held market share from Chrome, Firefox and Brave. In this article we will take a brief look at the latest AI-Browsers in the market and what they offer, ChatGPT Atlas, Perplexity Comet and BrowserCompany’s Dia.
Perplexity Comet
Comet, by Perplexity has been one of the first companies to announce that they are working on a browser. Comet is based on the open-source Chromium project by Google and adds several AI features on top of it.
The first noticeable thing when you open a new tab in Comet is that it defaults to Perplexity as its “search-engine”, you can enter your commands, search queries and it will show the best results first, in its Assistant tab, which includes an AI generated summary in the bottom. There is a separate sources tab, which shows what a traditional browser would show, a set of websites. Here I have searched for “Meteor showers in 2025”.
When you navigate to a web-page, there are several utility functions included in the right-sidebar, where you can open an Assistant and ask about the currently opened window, a voice mode to “talk” with your webpage and a separate Summarize button.
This AI sidebar assistant could be named as one of the major features of the browser where users are able to ask their questions in natural language about the opened webpage.
There are several other agentic capabilities built in to Comet as well, but Im not going through them in details in this article.
BrowserCompany Dia
The BrowserCompany rose to fame after their Arc browser, which became very popular on MacOS specifically. But eventhough the success with Arc browser, they announced that the development of Arc is no longer done and that they are working on a new, AI centric browser, Dia.
Same as the previous Comet browser, this is also based on Google’s Chromium and offers several AI centric features on top of that. When you open Dia and type in the search bar, its just like a normal browser and uses Google as the default search engine to display results, which is drastically different than Comet.
When you navigate to a web-page, it offers the same AI-Sidebar assistant similar to Comet, in this case its the Chat button in the top-right.
The AI-Sidebar offers, analyze, explain and summarize buttons and you can ask any question similar to a typical LLM, about the web-page. Also, when you have several tabs open, in a new tab search box, you can mention your open tabs and ask questions about them, and it will answer similar to a LLM based on your mentions.
Apart from that, Dia adds several agentic capabilities and Skills, which are handy tasks like Summarize, Explain, Proofread, Explain PR, Review, which we can invoke from any webpage.
ChatGPT Atlas
Now the big one, today (22/10/2025) OpenAI announced their entrance to the browser wars with their Atlas browser. It is also, Chromium based (!) and currently generally available only on MacOS. Let’s have a brief look.
Similar to Perplexity Comet, Atlas has a ChatGPT based home-page, where you can enter your prompts and websites. When you enter a prompt in the “search-bar” and you click enter, you get an AI generated answer about the question, with several tabs available on top.
Those tabs/sub-tabs on top are, Search, Images, Videos and News. If you navigate to the search tab, you can see a typical search result, with a list of websites. And the rest of the tabs work similar to a typical google result image, video and news tab.
When you navigate to a website, similar to the previous two brosers, there is a AskChatGPT button, which opens, to no-ones surprise, an AI sidebar.
Here, you can ask anything about the opened website and it will answer. There are several other agentic capabilities built-in for Pro users and other features such as memories, Cursor (Which can help inject text and alter in browser)
If we take a look at the three browsers we looked at above, we can see several similar things.
- Based on Chromium
- AI Sidebar to ask questions
- Agentic capabilities at a cost
- AI-Native
These points seems to be the common features of modern AI browsers (Is that the correct term ? ). Most other features feel like gimmicks and not useable in a daily-basis. So we have to ask the question, do these AI Browsers add anything other than a few agentic workflows and a “LLM Wrapper” on top of Chromium ?
When I compare the 3 browsers with each-other, ChatGPT Atlas seems to be the best one which offers a mix of typical browsers + AI integrations. It seems to have figured out the sweet spot between AI and “legacy” browsing.
But for a typical user, we need to ask whether we would be using all these added-features on top of Chromium on a daily basis, or would it complicate the simple web-search more than necessary. Its too soon to tell how would the general public adapt to these AI browsers, or would it be just noice in Google/Firefox/Safari’s domination on browsers.
I hope you gained some insights into these AI browsers, and the “new” way to browse the web. Please leave your ideas and feedback as comments.
