| Kai's verdict | 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. | S-tier for solo + free. The best free option, hands down. |
