Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
