Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
