Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.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.
