The Browser Company Retires its Arc Browser and Pushes Users to Dia
The Browser Company 宣布 Arc 浏览器将于 12 月 22 日停用，并邀请用户迁移到其新的 AI 浏览器 Dia，后者目前支持 Apple Silicon Mac 和 Windows 11 PC。停用分阶段推进：即日起无法注册新 Arc 账号，11 月 23 日 iOS 和 Android 版 Arc 的标签同步、Browse for Me 等 AI 功能将被关闭，12 月 22 日桌面版停止工作、Arc 账号停用。公司称同时维护两个浏览器在安全上难以成立，Dia 支持侧边栏垂直标签、Spaces（现称 Profiles）、固定标签、文件夹和分屏视图，并可在注册时导入登录信息、扩展等用户数据。

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.
