Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Still early. Manus is more flexible for less money.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
