Arc browser to shut down Dec. 22 as The Browser Company shifts to Dia

The Browser Company will shut Arc on Dec. 22, 2026, phasing out accounts and mobile features as it shifts users to Dia.

The shutdown is set in stages. On Nov. 23, the Browse for Me feature and “other AI features” will be disabled on iOS and Android, and users will no longer be able to sign in or sync their tabs, according to the Arc post. On Dec. 22, Arc will not be accessible on macOS or Windows, Arc accounts will be deactivated and Arc Search for Android will be removed from Google Play.

The Browser Company said its security work is now centered on Dia. “Our priority is to deliver best-in-class security for our members,” the company said, according to 9to5Mac. “Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. 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 Verge reported that the company’s “whole security team” is now focused on Dia.

For users who move to Dia, Engadget reported that bookmarks, extensions, passwords and history will transfer automatically. 9to5Mac reported that Spaces, Folders and Tab Groups will import with data intact; that Dia now exceeds Arc benchmarks in stability, speed and security, according to the company; and that browser features used in Arc are free in Dia, with AI features optional. The Browser Company has published an FAQ on importing data into Dia.

Arc’s desktop browser put The Browser Company on the map, 9to5Mac reported, but the firm later shifted its focus to a second attempt at the desktop browser market with Dia. Development on Arc had not been moving forward since May of last year. In its announcement, the company said: “We’ve decided to sunset Arc on December 22, 2026. That’s not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way.”

Dia was first announced last year and is a standard AI-based web browser, Engadget reported. It includes a chatbot that the company says can understand context across multiple open tabs, can summarize emails and YouTube videos, and produces a daily “morning brief” that integrates data from calendars, inboxes and web links. Dia is available for free, according to 9to5Mac.
