Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
