Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
