Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
