Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for speed. When latency is the product, start here.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
