Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.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. Still early. Manus is more flexible for less money.
