| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for teachers. If you teach K-12, start here this week. | S-tier for academic research. Nothing else comes close for systematic reviews. | A-tier. Bet on this one — the Sparkpage format is genuinely new. |
