Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
