Kai's verdictS-tier if you're on Mac. The fastest way to get AI answers without context-switching.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.S-tier for model-shopping. I use this for every prototype before committing.
