AI won’t exist as an app. Or a button. It’ll be an entirely new environment — built on top of a web browser.
Dia Browser is the latest project from The Browser Company (the same team behind Arc Browser), and while it’s an interesting experiment, it feels more like a stripped-down Chrome with an AI sidekick than an actual serious browser contender.
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).
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 (this will either immediately click for you as to what's possible, or not):
Sorta. The main competition going on right now is between Perplexity's Comet vs Dia. And while I see some promise behind Dia, I am definitely finding myself only using it for some personal searching. Like going in the depths on researching to buy something. It hasn't been able to replace Arc Browser as my day-to-day work and productivity-focused browser.
It's also incredibly difficult for me to break the habit (or even want to) use ChatGPT less (I use the desktop app, triggering it with CTRL + spacebar), and it seems the team really wants you to embrace their AI chatbot in-place of ChatGPT to get the full benefits (of getting your browser to learn and understand you.
With all of that, if you’re someone who just wants a clean browser with built-in AI to summarize articles or answer questions, speak to your open tabs and YouTube videos to help with research, then sure, Dia might be worth giving a shot. But if you actually care about productivity, speed, and having real control over your setup, Arc still feels lightyears ahead (yes, even in maintenance mode). It's clear that Dia was built for a totally different audience (e.g. my parents or those who haven't taken to embracing AI just yet, then absolutely yes, Dia feels like a solid gateway into this).
Zen Browser is heavily inspired by Arc Browser, with one core difference. It was built for those who want a Chromium alternative, but love the idea of a modern browser with a powerful sidebar, like Arc.
That said, with it being built atop Firefox, if you're moving over to it from Google Chrome or Safari, you're most notably going to notice how many browser extensions you use that don't exist in Firefox more than anything:
It's also built by a much smaller team, so you really have to just be somebody that absolutely loves Firefox, and wants to use a modern spin on that. That said, if youwant an Arc-like experience without the bugs? Just use Arc instead.
