Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for model-shopping. I use this for every prototype before committing.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
