| Kai's verdict | A-tier. Bet on this one — the Sparkpage format is genuinely new. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
