Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier. S-tier if you self-host. The reason open-source image gen matters.
