Kai's verdictS-tier for solo + free. The best free option, hands down.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
