Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier in its category. The first AI music tool I'd actually listen to.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
