Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier for social/casual. B-tier for serious work. Good entry point.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
