Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.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.
