Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier in its category. The first AI music tool I'd actually listen to.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
