Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier in the agent category. The first one I'd give to a non-technical friend.
