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. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for builders. The right primitives. What Kai is built on under the hood.
