| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | A-tier. Bet on this one — the Sparkpage format is genuinely new. | A-tier for creators training custom looks. B-tier for general use. |
