Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.	S-tier for builders. The right primitives. What Kai is built on under the hood.	A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
