Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
