The Browser Company 宣佈分階段停用 Arc，並引導用戶轉用 Dia

The Browser Company, which is developing the Arc web browser, announced today its upcoming retirement on December 22. The company is inviting Arc users to switch to Dia, its new AI web browser that’s currently available on Apple Silicon Macs and Windows 11 PCs.

In the message explaining why it was sunsetting Arc, The Browser Company explained that maintaining two separate browsers was difficult to justify, especially from a security perspective. “Dia was built from the ground up to meet today’s security standards, so that’s where our engineering and security teams will focus moving forward,” the company wrote.

The retirement of Arc will be gradual: While nothing changes for existing Arc users, it’s no longer possible to create new Arc accounts as of today. On November 23, tab sync, Browse for Me, and other AI features will be disabled on the iOS and Android versions of Arc. Lastly, the desktop version of Arc will stop working on December 22, and Arc accounts will be deactivated.

The Browser Company emphasized today that its new Dia AI browser supports popular Arc features such as vertical tabs in the Sidebar, Spaces (now called Profiles), pinned tabs, folders, and Split View. Dia can also import all user data (logins, extensions, Spaces, Favorites, pinned tabs, and folders) during sign-up.

In an FAQ, The Browser Company said that its new Dia browser is “a lot faster” than Arc, and its AI features are optional. Dia offers a natural-language Omnibox, a built-in AI assistant with an optional memory feature, multi-tab analysis, and custom AI skills. There’s also a Morning Brief feature that pulls together updates from users’ calendar, inbox, and connected apps like Slack.
