Kai's verdict	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.	B-tier. Still early. Manus is more flexible for less money.	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.
