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 in its category. The first AI music tool I'd actually listen to.S-tier for search. I use it before Google now.
