Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.
