Kai's verdict	S-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.	B-tier. Still early. Manus is more flexible for less money.
