Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	A-tier. Bet on this one — the Sparkpage format is genuinely new.	S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
