Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier. Bet on this one — the Sparkpage format is genuinely new.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier infrastructure. The one platform every AI dev eventually uses.
