Kai's verdictB-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.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for realtime. If latency matters more than voice catalog, start here.
