Kai's verdictA-tier for creators training custom looks. B-tier for general use.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
