Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
