About Dia
Dia is an AI-first web browser developed by The Browser Company as the AI-focused successor to the Arc browser.
What sets it apart is that AI chat is integrated directly into the browser interface, giving contextual assistance on pages and tabs rather than living in a separate app or extension.
It is a download for people who want AI built into browsing and are on macOS, offered free with optional paid features under a freemium model. It is not an option yet if you use Windows or Linux, since it is currently macOS-only, and as a newer product it has a smaller extension and feature ecosystem than established browsers.
Next to Chrome or Firefox, Dia trades that mature extension ecosystem for AI chat wired into the browser itself.
