AI is changing the way we use the internet—and traditional web tools are starting to feel outdated. That’s exactly the shift The Browser Company is betting on with the launch of Dia, a bold new browser that puts AI at its core.
After spending years building Arc, a browser loved by design and productivity enthusiasts, the company made a tough call last year: stop development. Arc was slick and innovative, but its learning curve proved too steep for most users. So, the team went back to the drawing board—this time with a laser focus on AI.
Enter Dia, now available in beta (invite-only for now). It’s not just another web browser—it’s a reimagining of how we use the internet altogether.
The company’s CEO, Josh Miller, has spoken openly about how deeply people are integrating AI into their everyday tasks. Whether it’s asking ChatGPT to explain a concept or using Perplexity to explore ideas, AI is already in the flow of how people work. Dia takes that idea and brings AI directly into the place where most of our work happens: the browser.
At first glance, Dia looks simple and familiar. It’s built on Chromium, so it has the structure and reliability of Chrome, but underneath, there’s a lot more going on.
The real magic is in the AI. Instead of just typing in a website or search term, you can interact with Dia’s AI directly through the URL bar. It can browse the web for you, summarize PDFs or documents you upload, and even pull insights from all your open tabs. Need to draft an email based on your research? Just ask—it’ll write it up.
You can even customize the way the AI communicates. Want a casual tone? Prefer concise answers? Looking for coding help in a specific language? Just tell the chatbot, and it adapts accordingly.
There’s also an opt-in feature called History, which allows Dia to use the past seven days of your browsing activity to give more personalized, contextual responses. So instead of repeating what you’re working on, the AI already knows.
Then there’s Skills—a feature that lets users create their own custom mini-automations. It’s kind of like Siri Shortcuts, but for your browser. For instance, you can build a one-click reading layout or automate how certain tabs behave.
Of course, Dia isn’t the first browser to dabble in AI. Tools like Opera Neon and Chrome are already rolling out their own smart features. But The Browser Company is aiming for something deeper—a browser that feels less like a static tool and more like an intelligent assistant, always one step ahead.
Existing Arc users will get immediate access to Dia, and current Dia beta testers can invite others to join.
