Kai's verdictB-tier overall, A-tier if GDPR/data residency matters. Solid backup option.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.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
