Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Still early. Manus is more flexible for less money.
