Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
