Dia browser, an AI powered successor to Arc browser- What is it? (Explained)

Dia is an AI-powered browser with an integrated chatbot, personalized features, and strong privacy, currently in closed beta with no final release date yet.

Dia is a new AI-powered browser released by The Browser Company, the same developer behind the popular browser Arc, released in 2022. But unlike the Arc browser, Dia looks and feels similar to a normal browser. It features an AI-powered chatbot that writes for you, answers your questions, and does much more without you needing to leave the browser tab. Here’s everything to know about the Dia browser.

By Amit Rahi

For the past seven years, I have tracked consumer tech through constant shifts in hardware, platforms, and the way people actually use devices. Covering everything from budget gear to flagship hardware, I focus on what readers need to know, not on buzzwords or launch cycle hype. My expertise spans gaming laptops and chairs, high-performance PCs, gaming monitors, printers, smartwatches, earphones, headphones, Bluetooth speakers, tablets, and more, with a particular emphasis on how these products hold up in daily use. Reviews, explainers, buying guides, and news pieces all share the same goal: giving readers enough detail to make confident decisions without wading through fluff. Away from deadlines, I spend a lot of time gaming and watching films and anime, which naturally filters back into the work. Performance, comfort, display quality, and sound are judged the way players and viewers experience them, not just by lab numbers, which keeps my coverage grounded in real scenarios rather than just benchmarks.

Dia browser’s key features

• Integrated AI assistant: The one standout feature is the integrated AI chatbot that can be accessed anytime. This assistant can access and synthesise information from all your open tabs and even your recent browsing history. This helps the chatbot to give you smarter and more contextual responses. The chatbot can answer questions, summarise webpages, write or improve your content, and even compare information across multiple tabs.
• Skills: You can build small AI tools to automate quick tasks like writing, shopping, scheduling, and to autofill forms.
• Horizontal tabs: Unlike the vertical tabs that we saw on the Arc browser, Dia uses a more familiar and functional horizontal tab design.
• Chromium-based: The browser is based on Google’s open-source Chromium to ensure compatibility and a smooth browsing experience.
• Privacy: All the data is encrypted and saved locally, with only milliseconds-long server processing.

How Dia is different from other browsers

Instead of simply adding a chatbot to a browser like Chrome or Edge, Dia is built from the ground up with AI at its core. This makes AI a natural part of every browsing action. Dia learns from your history and recent browsing actions to offer more personalised results.

The AI chatbot delivers a seamless AI experience, eliminating the need to copy and paste content into separate AI tools. It uses context directly from your open tabs, making it a powerful tool for research and productivity
