The Browser Company’s Dia AI Browser is Now Available for All Mac Users

Dia, the new AI browser developer by The Browser Company, is now available for all Apple Silicon Mac users. Dia first launched in beta on macOS back in June, three months before Atlassian announced that it was acquiring The Browser Company.

I had never tried Dia until today, and the web browser will ask you to create an account upon launch. Dia lets you import your passwords, history, and bookmarks from other browsers and also offers different theme options, which are two standard features.

As an AI-driven browser, Dia offers a chat window on its new tab page, and the chat interface can also be enabled on any tab. This lets you ask a question about the current page, summarize it, mention other tabs to add content, and more.

Less invites, more ships.

Dia is now open to everyone on macOS.

When asking Dia’s chatbot a question, that request is either routed to a search engine or a “trusted AI partner.” Dia’s chatbot can also personalize its answers with its optional Memory feature, which can remember recent sites, chats, and other preferences.

On the privacy front, the Browser Company says that any content data shared with Dia, including browser history and questions asked to the chatbot, is never tied to users’ accounts and is deleted after 30 days. Users can also delete their data at any time and block ads, trackers, and cookie banners on the web.

I’ll need more time to play with Dia, but the AI web browser is now on a weekly release schedule. The latest update to the browser brought the Focus Mode from The Browser Company’s Arc browser, Memory upgrades, and redesigned Skills, which are shortcuts for repeatable workflows.
