Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
