Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier in its category. The first AI music tool I'd actually listen to.B-tier. Still early. Manus is more flexible for less money.
