Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.A-tier for creators training custom looks. B-tier for general use.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
