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.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Still early. Manus is more flexible for less money.
