Dia

Dia is a web browser designed for work productivity, developed by The Browser Company. It includes a built-in AI assistant that can access information across open tabs and connected applications to answer questions and generate outputs. The browser helps users organize their work by providing features like a morning briefing that summarizes calendar, inbox and key links, the ability to synthesize information from scattered tools like Slack, Notion and Teams into shareable reports, and search across connected applications to find answers in context. Users can create separate profiles for different aspects of their work, organize tabs into groups, and view multiple windows side by side. The browser includes options to generate presentations from context and set up meeting pages with agendas and related documents.

Dia is available for free download on macOS, with Windows support coming later. The browser is designed with privacy as a priority, allowing users to control data sharing and preferences. The developer offers Dia for Work as an option that includes team-focused features like single sign-on.
