What happened

Key facts

  • The company said maintaining browser security requires increasing effort in the age of AI and that its engineering and security teams will focus on Dia.
  • Arc users will no longer be able to sign in or sync tabs.
  • The company will end Arc on December 22 and direct users to its newer AI browser, Dia.
  • The company will discontinue some Arc account services.
  • Arc will continue to work as a basic local browser.

The brief

The Browser Company plans to discontinue its Arc browser on December 22, 2026, and steer users toward Dia, its AI-first browser. The company described the change as a staged wind-down: Arc will lose some features and services before the planned shutdown, but it will remain usable as a basic local browser, TechCrunch reported.

The first stated change is scheduled for November 23. Arc Search on iOS and Android will lose its AI capabilities, including the “Browse for Me” feature. Later, Arc users will no longer be able to sign in or synchronize tabs. The company says the app will still function locally, although those account-based services will no longer be available.

The Browser Company attributed its decision to the work required to maintain browser security as AI becomes more prominent. It said that this work is growing and that its engineering and security teams will concentrate on Dia.

The company described Dia as built to meet current security standards; that is the company’s stated assessment and rationale for directing its teams there. The shift does not mean every Arc feature will disappear from the company’s products.

CEO Josh Miller said Arc runs on the proprietary Arc Development Kit, which also powers Dia, and characterized that technology as central to the company’s value. The company also said Dia will include equivalents of several core Arc features, though the account did not identify those features individually.

Arc’s planned end date was also stated in a UA.NEWS headline, which said The Browser Company plans to shut down the browser on December 22. TechCrunch reported the same date and described the steps preceding it, including the mobile AI changes and the eventual loss of sign-in and tab syncing.

For Arc users, the practical transition described by the company is from an app with AI and account features to one that continues as a local browser, alongside a move toward Dia. The company’s stated plan places Dia at the center of its future engineering and security work, while preserving some Arc capabilities there.

The account does not provide further details about how users would move their data or when the sign-in and synchronization services will end.

Why it matters

  • Arc users face the loss of AI functions on iOS and Android, including “Browse for Me,” on November 23.
  • Users will lose sign-in and tab syncing; the stated alternative is continued local use of Arc as a basic browser.
  • The Browser Company says its engineering and security teams will focus on Dia, which it says will provide equivalents of several core Arc features.

What to watch next

  • Whether Arc Search on iOS and Android loses its AI features, including “Browse for Me,” on November 23.
  • Whether the company ends Arc on December 22, 2026, as planned.
  • When the company ends Arc sign-in and tab syncing, which it says will no longer be available.
