| Kai's verdict | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. | S-tier for academic research. Nothing else comes close for systematic reviews. | 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. |
