Kai's verdict	A-tier if you already pay Gemini. B-tier standalone.	S-tier for builders. The right primitives. What Kai is built on under the hood.	A-tier. Close second to Cursor. If $5/mo matters, start here.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
