Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.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.
