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.A-tier. Best for fast prototypes. Competitive with Lovable — try both.S-tier for model-shopping. I use this for every prototype before committing.
