Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Still early. Manus is more flexible for less money.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
