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.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
