What Dia is

Dia is a macOS web browser with an assistant for questions and requests about the current page, other tabs, selected text, and browsing history. Its free plan includes profiles, tab groups, split view, picture-in-picture, ad and tracking blocking, and cross-device sync, but no AI features. Better Answers costs $20 a month and adds AI answers and contextual chats; Better Days costs $100 a month and provides six times more usage than Better Answers plus additional work features. AI usage is measured in Tasks, resets each billing cycle, and pauses at the limit unless the user adds more. Extra usage is available in 20 USD credit blocks, and purchased blocks can roll over for up to three months. Profiles can separate work, freelance, and personal tabs, logins, and AI contexts. Dia also offers Morning Brief, reusable Skills, and connections to tools including Slack, Gmail, Notion, Outlook, GitHub, Google Calendar, and Figma. The company says it does not sell personal data or use browsing data to build ad profiles, and that Sync is end-to-end encrypted.
