Kai's verdictA-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for designers. The only one that takes vectors seriously.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Still early. Manus is more flexible for less money.
