The Rise of AI Browsers: Beyond Chrome and Safari
First it was Dia, then came Comet. I downloaded Fellou.ai the other day, which bills itself as the first "agentic browser." As I type this I'm also installing GenSpark's new AI browser. (Apparently I collect browsers now. Don't judge.)
The browser wars are heating up again, but this time it's not about speed or extensions—it's about intelligence. These aren't just browsers with chatbots bolted on; they're fundamentally rethinking how we interact with the web.
What Makes a Browser "AI-Powered"?
The Purist Definition
A browser with native reasoning and page context—true understanding of what you're looking at and doing across tabs.
The Practical Reality
A regular browser with AI that can read your tabs, act across pages, and save you from endless copy-paste gymnastics between sites and ChatGPT.
Think about how we used to work online: the internet gave us speed, but also noise. You could search and find plenty of information, but actually rationalizing it was still a manual process. Most of us ended up doing the dance—search, skim, then paste snippets into ChatGPT or Claude.
The Evolution from Text to Agentic Behavior
1
Text-Only Era
ChatGPT launches with pure text interaction. Copy-paste becomes our workflow.
2
Multimodal Breakthrough
Models can process images and screenshots. The dance gets shorter—paste a screenshot, let the model read it.
3
Browser Integration
AI browsers emerge, removing the shuttling between tools. One context, infinite possibilities.
4
Agentic Future
Not just "summarize this" but "compare those," "book that," "fill this out"—all inside the browser.
As LLMs improved and multimodal arrived, that dance got shorter. Within about 18 months of ChatGPT's launch, multimodal became table stakes, and it already feels quaint that these systems once only handled text.
The Players Reshaping Web Browsing
This isn't exhaustive—with the current pace, two more browsers will probably launch next week—but here's the current field of AI-powered browsers making waves:
Dia (The Browser Company)
"Chat with your tabs," skills, and memory based on your real browsing. Plot twist: Atlassian is acquiring them to push Dia into enterprise workflows.
Perplexity Comet
The most "agentic" right now. Compare products, click/type/submit across sites, search your history, even manage email and calendar. Chromium-based and expanding fast.
Microsoft Edge Copilot
Lets Copilot see your tabs to summarize and compare. Free, opt-in, with clear indicators. Marching toward booking and other actions.
The Full Competitive Landscape
Chrome (Gemini Integration)
Page-aware summaries baked into Chrome. Helpful, but feels more like a feature than a full product—no multi-tab awareness or task execution yet.
Safari (Apple Intelligence)
Adds Summarize/Highlights in Reader mode. Privacy-forward, mostly on-device processing. Early steps, not yet at Dia/Comet levels of sophistication.
Brave (Leo)
Privacy-first with multi-tab context. In practice, results were inconsistent—it can summarize, but struggles with real actions like managing emails.
Opera (Aria)
Free, integrated across Opera ecosystem. Useful for quick answers, but limited in action-taking and suffers from clunky overlay UI design.
My Real-World Testing: Which Browsers Actually Work?
Full disclosure: the next section focuses on Dia, Comet, and Fellou, mainly because I've been living in Dia and Comet for the past month, and just spent considerable time testing Fellou. Here's my snapshot take on the entire field:
1
Dia – A Great Browser
Smooth, intuitive, genuinely fun to use. My only gripe: no tab groups, which becomes a real workflow limitation.
2
Comet – My New Default
Tab groups plus productivity features are absolute game changers. The ability to take real action sets it apart.
3
Chrome/Edge – Solid but Limited
Good for summaries, but no multi-tab awareness or task execution. Feels like add-ons, not full products yet.
4
Safari – Early Promise
Interesting touches like distraction mode, but nowhere near Dia/Comet sophistication. More "AI features" than "AI browser."
Hands-On: Dia vs. Comet (And Why I Switched)
AI browsers shine when one tab needs information from another. Instead of bouncing back and forth or copy-pasting, you can simply ask: "@PizzaPlace what's the total for this order?" The example may be pizza, but the real win is research—referencing data across tabs without breaking your flow.
Dia's Strength: Deep Context
Dia's superpower is deep tab context. Writing help, document review, contextual suggestions—all solid. It excelled at item comparisons and value assessments, making it an excellent research companion.
But when I asked it to do a recipe-to-shopping test, it gave me the recipe and ingredients list perfectly but couldn't update the cart.
Comet's Edge: Real Action
Comet can actually do things for you. I opened 15 messy tabs, and Comet organized them into categories: NFL & Sports, News, AI & Tech, Social, and Courses & Learning. Simple but powerful.
I then asked it to find recipes and populate my shopping cart with ingredients. It executed flawlessly—this is the difference between summarizing and acting.
Why Comet Won Me Over
Here's my hot take: Comet and Dia are remarkably similar in core functionality. Both excel at contextual reasoning and cross-tab queries. But for me, one feature tipped the scales: tab groups. Dia doesn't have them; Comet does. That's it.
Auto-Organization
Comet automatically sorts your chaotic tabs into logical groups, saving mental energy for actual work.
Agentic Tasks
Scheduled custom alerts, reminders, and reports. Create a query, set a schedule, get updates by email or push notification.
Real Execution
Beyond summaries and comparisons, Comet can click buttons, fill forms, and complete multi-step workflows across different sites.
That said, Dia does have a clever split-tab view—multiple tabs inside one tab—which I still love for certain research workflows. But Comet's ability to take action, actually execute tasks for you, plus tab groups and auto-organization make it the more practical daily driver.
Fellou.ai: A Cautionary Tale
Fellou is a new player billing itself as "the world's first agentic browser." Familiar claim, but it does feel different. Its pitch: spin up "shadow workspaces" that run tasks in parallel, schedule daily portfolio analysis, job hunt from your resume, even prioritize your inbox. Sounds powerful.
The problem? Cost.
The Pricing Reality
Fellou's Plus plan costs $19.90/month for 2,000 credits. I tried their own showcase example, estimated at 400–1,400 credits. It choked on a captcha, I solved it manually, then it failed with an unhelpful error message.
The Credit Drain
My failed example depleted my points anyway. I paid $20 for 2,000 points and basically got one broken demo run. The math doesn't work—if one task costs $20, I'm not using it, no matter how generous my expense account.
Red Flags to Watch
Charging credits for failed tasks, inconsistent credit deduction (2 credits once, then 941 the next), and charging points for social media follows all signal a problematic business model.
The Future is Already Here
AI browsers are here, and they're powerful, useful tools. If you aren't already using one, you will be soon. The "AI browser" won't replace Chrome, Edge, or Safari—those browsers will simply become AI browsers.
Google's already shipping Gemini in Chrome; Microsoft has Copilot Mode; Apple is weaving Apple Intelligence into Safari. Within a year, every major browser will have native AI that can reason over your current page, your tabs, and (with permission) your history.

Major Acquisitions
Like Atlassian acquiring Dia, reshaping the landscape
Cool features aside, only some of these models are sustainable. Opera makes money the old-fashioned way (search plus ads). Perplexity is betting on subscriptions and enterprise. Indie players like Brave are fighting uphill without those default-search revenues. Who pays ultimately decides who survives.
And that's why I like writing these pieces: not just to track what's shipping, but to test them, break them, and show you what actually matters. The browser wars are back, and this time, intelligence wins.
