Arc browser users have two months to prepare for a major change. The Browser Company has announced that Arc will stop working on December 22, 2026, as the company moves its focus to its newer AI-powered browser, Dia.
Arc became popular for its different approach to browsing. It offered vertical tabs, workspaces called Spaces and tools designed to help people organise many open pages. The new shutdown announcement means users need to plan how they will keep their browsing data and move to another browser.
The change will happen in stages. Some mobile features will stop working before the desktop browser reaches its final shutdown date.
Arc shutdown dates
Date What changes October 22, 2026 New Arc accounts stop being accepted. November 23, 2026 Mobile AI features, sign-in and tab synchronisation end. December 22, 2026 Arc stops working on macOS and Windows, and account services are deactivated.
After account deactivation, personal data is scheduled to be deleted within 30 days. Users should not wait until the final day to save information they want to keep.
What Arc users should do now
The first step is to review what is stored in Arc. This may include bookmarks, browsing history, passwords, extensions, Spaces, folders and tab groups.
Users should export any data they want to keep and confirm that the exported files can be opened or imported elsewhere. Important passwords should be stored in a trusted password manager rather than left only inside a browser account that is about to close.
People who use Arc for work should also check whether their saved tabs contain important project links, research pages or client information. Keeping a separate list of essential links can make the move easier.
Before deleting the browser or its account, users should confirm that their data has been transferred successfully. A browser migration is a good opportunity to remove old bookmarks and check which extensions are still needed.
Why the company is moving to Dia
The Browser Company has been shifting its development work towards Dia, a browser built around AI features. The company says it wants to concentrate its engineering and security resources on one product instead of maintaining two separate browsers.
Dia is intended to offer a more integrated experience in which AI can help users work with information across tabs and tasks. However, users should review its privacy controls and decide whether they want AI features enabled.
The shift reflects a wider change in the browser market. Companies are experimenting with AI tools that can summarise pages, help with research and assist with multi-step tasks. These features may be useful, but they also make it important to understand what information a browser can access.
What happens to Arc’s best features?
Arc’s vertical tabs, workspaces and split-view layout helped it stand out from traditional browsers. Some of these ideas have influenced the wider browser market, and Dia is designed to carry forward parts of Arc’s approach.
However, users should not assume that every Arc feature will work exactly the same way in Dia. Before switching, check that the new browser supports the tools and workflows you rely on.
People who prefer a more traditional browser can also consider other options. The right choice depends on the operating system, privacy needs, extensions and how much help the user wants from AI.

Passionategeekz Take
Arc’s shutdown is a reminder that software services can change even when people depend on them every day. Users should export important data, review their browser extensions and test their replacement before December 22. Dia may be a suitable option for people who want an AI-focused browser, but the best choice depends on individual needs and privacy preferences.
