The Browser Company is shutting down its Arc browser on December 22 and encouraging users to migrate to Dia, its newer AI-powered browser for Apple Silicon Macs and Windows 11 PCs. Thurrott reports: In the message explaining why it was sunsetting Arc, The Browser Company explained that maintaining two separate browsers was difficult to justify, especially from a security perspective. "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 company wrote. The retirement of Arc will be gradual: While nothing changes for existing Arc users, it's no longer possible to create new Arc accounts as of today. On November 23, tab sync, Browse for Me, and other AI features will be disabled on the iOS and Android versions of Arc. Lastly, the desktop version of Arc will stop working on December 22, and Arc accounts will be deactivated.Read more of this story at Slashdot.
