Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for model-shopping. I use this for every prototype before committing.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
