Kai's verdictA-tier. Best for fast prototypes. Competitive with Lovable — try both.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-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.
