Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for builders. The right primitives. What Kai is built on under the hood.
