What’s different
No AI
Dia is built around AI chat, with paid plans. Dawn has no built-in AI, and nothing to pay for.
Spaces stay spaces
Moving from Arc to Dia turns spaces into profiles. Dawn keeps them as spaces, with their pinned folders.
Tabs that put themselves away
Tabs you didn’t pin archive themselves after 12 hours, and the command bar still finds them.
Where Dia wins
It’s Arc’s official successor: it brings over passwords, history, and extensions from Arc, and it runs on Windows.
