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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for model-shopping. I use this for every prototype before committing.
