Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier in its category. The first AI music tool I'd actually listen to.
