Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
