Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Still early. Manus is more flexible for less money.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
