Kai's verdictA-tier for designer-led sites. S-tier if animations matter.S-tier for builders. The right primitives. What Kai is built on under the hood.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
