Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Still early. Manus is more flexible for less money.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
