Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. Best for teaching a kid to code in 2026.
