I'm actually not all that opposed to some of these features, but the way it's implemented is so clunky. The UI make it feel like a half baked browser extension.
"automatically group and label your tabs" is the only thing out of those that sound at all interesting to me, though I don't know how AI comes into play here. And is it all local AI?
It’s local and it tries to group the tabs based on what seems to be URL and title, and what seems to be a semantic content of the page (eg it understands to group shopping sites together).
