Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in its category. The first AI music tool I'd actually listen to.
