Dia Browser is one of the latest AI web browsers from The Browser Company (the same team who built Arc Browser).

After The Browser Company got acquired by Atlassian for $610M, they were given the full resources to double-down on their AI browser, Dia.

Dia is for those who are super excited about agentic browsers (think of a baked-in AI chat sidebar, that can co-pilot the browser with you at times).

• Dia has one of the most performant browsers out of all the current AI browsers on the market.
• Backed by the same team as the beloved Arc Browser, much of what made Arc great has been making its way to Dia.
• Since getting acquired for $610M, they now have the full backing of a $20B+ publicly traded company (Atlassian), to experiment and build in one of the most expensive and competitive spaces in the market.

• Dia hasn't decided to go the path of Agent Mode (controlling your browser for you), type features that both ChatGPT Atlas and Comet have gone deep into. So if you're looking for that, it's not likely coming.
• They can't currently use your actual ChatGPT history, so while their chat experience is beautiful and works well, I do at times wish I had more of the context from my ChatGPT account.
• They don't yet have a mobile app for iOS or Android, which feels important for something as core as your browser.

The same powerful (optional) sidebar that first put Arc Browser on the market, and that everyone else copied (including ChatGPT Atlas and even Chrome), is in Dia, and more refined than ever.

If you're someone that likes the idea of being able to have pre-built prompts that can be ran that interact with and take into consideration the content on the page you're visiting, then you'll love their "Skills" functionality.

Dia is currently totally free, with an optional $20/mo tier, that unlocks unlimited AI chat limits.

That said, you'd be hard-pressed to hit limits on the free tier, I only hit it once, and I was doing some pretty deep shopping research, referencing dozens of tabs and YouTube video content.

Dia is one of the leading AI browsers in the space, arguably with the most talented and thoughtful product and design team behind it (and now with Atlassian's backing, nearly infinite resources at their hands).

Dia is definitely worth giving it a try, the only question is really whether or not you're open to switching browsers or not. As that's likely the largest blocker. Although, if you're on this page right now, that's likely exactly what you're looking to do, so yes, Dia is worth giving a shot, especially if you've never tried and AI browser.

Shift is a tool that I've tried incredibly hard to like over the past 7+ years. The day I first found it, I was so stoked with it, until learning that it didn't have all of the Chromium extension support.

They've since made major strides on that front and have most extensions now supported, but it's beginning to feel a bit like a relic from the past, and pales in comparison to that of the more recent entrants into the space like Arc Browser and SigmaOS. In-fact, comparing Shift alongside Sidekick Browser and you'll be sure to confuse them with one another.

I just have a tough time recommending them at this point, they really just allow for your favorite apps to be pinned on the sidebar and easy account switching with some quick action features.

They'd like to focus on the productivity users, but we feel like you can get most of the positives of Shift in your existing browser by utilizing a tool like Workona or Toby.

If you're unwilling to install a new browser, stopping to use your beloved Chrome, Safari, or Firefox, well, you'd be hard-pressed to even give this browser a shot. We just don't feel like it innovates enough to actually take over your primary browser replacement, especially when looking at Shift vs Arc Browser for example.
