Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for sales teams. B-tier for solo users.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
