Dia vs Mind Browser

Dia is a macOS web browser with an assistant for questions and requests about the current page, other tabs, selected text, and browsing history. The free plan includes profiles, tab groups, split view, picture-in-picture, ad and tracking blocking, and cross-device sync, but has no AI features. Better Answers costs $20 a month and adds AI answers and contextual chats. Better Days costs $100 a month and includes 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 buys additional usage. Extra usage is available in $20 credit blocks, which roll over for up to three months. Profiles can separate work, freelance, and personal tabs, logins, and AI contexts. Morning Brief gathers calendar, inbox, and key links; Skills let users save frequent requests for reuse. The plans page lists connections to Slack, Gmail, Notion, Microsoft Outlook, GitHub, Google Calendar, and Figma. Dia says it does not sell personal data or use browsing data to build ad profiles, and that Sync is end-to-end encrypted.
