Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier for social/casual. B-tier for serious work. Good entry point.
