How Arc will wind down
TechCrunch reports that new Arc accounts can no longer be created as of October 22. On November 23, Arc Search on iOS and Android will lose AI features, including “Browse for Me.” Users will also lose the ability to sign in or sync tabs, although the app will continue to work as a basic local browser.
On December 22, Arc accounts will be deactivated and the desktop browser will stop working, according to TechCrunch. The outlet says personal data will be deleted within 30 days, and Arc Search will be removed from the Google Play Store. Engadget also reports that users will lose access to their Arc accounts on December 22.
The Browser Company cited the continuing work required to keep a browser secure, particularly as AI becomes more prominent, TechCrunch reports. The company said Dia was built to meet current security standards and will receive its engineering and security teams’ attention.
What users can take to Dia
The company is encouraging Arc users to move to Dia. Both TechCrunch and Engadget report that bookmarks, extensions, passwords and browsing history will transfer. They also say Dia’s AI features are optional.
Several familiar Arc tools will have counterparts in Dia, according to TechCrunch. Profiles replace Spaces for switching between environments such as work and personal browsing. Vertical tabs remain available as an optional sidebar, while Folders become Pinned Tab Groups. TechCrunch says Arc features will remain free in Dia.
Engadget describes Dia as an AI browser with a chatbot that the company says can use context from multiple open tabs. The outlet also reports features for summarizing emails and YouTube videos, as well as a daily brief drawing on calendars, inboxes and web links.
Why Arc is not being released as open source
TechCrunch reports that some disappointed users renewed calls for Arc to be made open source. CEO Josh Miller has previously said that Arc depends on the proprietary Arc Development Kit, which also powers Dia; releasing Arc in a meaningful way would therefore require releasing technology central to the company’s business.
The shutdown follows The Browser Company’s decision to stop active feature development on Arc in 2025, TechCrunch reports. The outlet says the company acknowledged that Arc’s distinctive interface attracted devoted users but that its complexity limited broader adoption. Atlassian acquired The Browser Company for $610 million in 2025, according to TechCrunch.
