Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
