The Browser Company launches Dia, its AI-based context-aware browser in beta for Arc users

The Browser Company has finally launched the beta of its new AI-first browser, Dia Browser, available exclusively to existing Arc Browser users on macOS. Following Arc’s discontinuation, Dia takes a more focused and practical approach that is now deeply centered on AI integration, while adopting a design closer to traditional browsers.

At its core is a context-aware AI assistant that interacts with tabs, browsing history, and sessions. It uses a customizable system of “skills” for specific tasks like writing, research, shopping, and messaging. Each skill relies on tailored AI models and interfaces, and can recall previous activity such as visited sites or writing habits to provide more relevant help.

Dia can summarize pages, compare content across tabs, draft emails in the user’s style, and use past searches for added context. Privacy is emphasized: user data is encrypted and stored locally, with any cloud-processed data deleted within milliseconds. While it currently lacks features like side-tab organization and workspaces, these may be added later.
