Kai's verdictA-tier for social/casual. B-tier for serious work. Good entry point.B-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 for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
