Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for builders. The right primitives. What Kai is built on under the hood.B-tier. Still early. Manus is more flexible for less money.
