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.

The new home for your internet on MacOS—One window. Many workspaces. All your tabs.
SigmaOS is a super interesting primary browser contender in the space. In the myriad of productivity-focused browsers out there, we believe that Arc vs SigmaOS are the two leaders in the space.
SigmaOS tried to re-think how a browser layout should be, and build in layers of productivity along the way (not too dissimilar to that of Arc).
The thing is, Sigma has quite minimal funding, and in the browser space, you're competing with companies that have billions of dollars to throw at improving the browser (Google Chrome, Edge, Safari), so when comparing it to those, it's tough to see how they'll manage to compete.
That said, even just comparing SigmaOS to that of Arc, Arc has raised over $100M to take on this incredibly competitive space, whereas SigmaOS is trying to fight having raised likely less than $2M. It's also tough to understand if people are actually willing to pay for a browser, and at $20/mo on the paid tiers for SigmaOS, it just feels like Arc is the more likely winner here.
SigmaOS does make some pretty different opinionated design decisions though, it's worth a shot checking out if you want to try something fresh and new, though not sure we'd bet on it ultimately taking up any meaningful browser marketshare.
