Dia

Dia is an AI-native browser developed by The Browser Company, the team behind Arc, whose core feature is seamlessly integrating conversational AI into the browsing experience. With its "chat with your tabs" capability, users can interact directly with the content of the current page, multiple tabs, selected text, or browsing history — without switching apps or windows.

• Tab-aware AI: Understands and synthesizes content across multiple open tabs, supporting cross-tab comparison and analysis
• Skills automation: Reusable natural-language workflows let you create custom shortcuts without coding
• Full-scenario support: Covers everyday tasks like writing polish, summarizing content, study planning, product comparison, and translation
• Controllable privacy: Users fully control data-sharing permissions, with privacy protection emphasized

In practice, students can open multiple academic papers at once in Dia and generate comparative reviews by @-mentioning individual tabs; online shoppers can open several product pages and have the AI produce a detailed feature-and-price comparison table; content creators can use the built-in writing assistance to quickly refine copy.

Dia currently supports macOS 14 and above (Apple silicon required), with both a free version and a Pro version ($20/month). Notably, The Browser Company has been acquired by Atlassian, which gives Dia stronger resources for long-term development.
