Kai's verdict	A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.	B-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.	B-tier. Useful for first drafts. v0 is the better bet for shipping code.
