Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
