Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.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.
