Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for text-in-image.
