Overview
- The company announced the formal shutdown date for Arc and told users they must migrate off the browser by December 22, 2026 or lose access.
- Dia is available for free on Apple Silicon Macs and Windows 11 and the company says it will import passwords, bookmarks, extensions, history, Spaces, Folders, and Tab Groups when users sign up.
- The firm claims Dia surpasses Arc on stability, speed, and security and that AI tools in Dia are optional rather than mandatory.
- The shutdown will roll out in stages, with new Arc account creation already closed and mobile AI features planned to be disabled ahead of full deactivation, according to the company’s timeline.
- The move follows a year of stalled Arc development and reflects a wider industry pullback from standalone AI browser experiments, leaving users to weigh Dia’s migration promises against other Mac and desktop alternatives.
