Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
