Kai's verdictA-tier. Best for fast prototypes. Competitive with Lovable — try both.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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
