Switch to Dia: Features and Migration Process

The Browser Company is actively encouraging users to switch to Dia, positioning it as Arc's natural successor with enhanced capabilities. Dia was first announced last year and represents a standard AI-based web browser with integrated AI features designed for AI-driven browsing3

New import tools make data migration seamless for Arc users. When installing Dia on macOS or Windows devices, the browser automatically prompts users to import directly from Arc, transferring bookmarks, extensions, folders, history, passwords, profiles, tabs, Spaces, Folders, and Tab Groups1

User Response and Market Implications

The social media announcement of Arc's shutdown faced significant pushback from users who claim Dia isn't as useful to them, with many requesting The Browser Company open-source the original browser1

. This resistance suggests Arc cultivated a dedicated user base that valued its unique features, including the ability to personalize any website while browsing and innovations like Split View1

.

Mozilla Firefox seized the opportunity to poll former Arc users about better accommodating them. Mozilla acknowledged that Arc's innovations influenced some of their own features, including Sidebar, Split View, and the upcoming Mini Window1

. Head of Firefox Ajit Varma told PCMag that his strategy is to build better features and a better browser to attract users1

.

It remains unclear whether The Browser Company intends to launch a mobile service to replace Arc Search, as there's currently no sign of a portable version of Dia1

. This gap in mobile offerings could drive Arc Search users toward Mozilla Firefox or other established browsers with robust mobile platforms. The Browser Company maintains that the team behind Arc is the same team developing Dia, promising that their most ambitious work lies ahead2
