How Arc concepts map
Dia imports Arc Spaces (as Profiles), Favorites, pinned tabs, folders, bookmarks, history, passwords and extensions directly (Dia > Import from Another Browser > Arc). Keep Arc installed until the import finishes; on Windows quit Arc first.
Watch out for
AI-centric product; paid tiers for AI usage. Boosts and Easels do not transfer. Spaces become Profiles, which is a different model from Arc's in-window Spaces.
