Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for local inference. If you care about privacy or want to tinker, install this today.
