SEO.ai scored 78/100 in our testing. SEO.ai was built as an SEO tool first and a writer second — the opposite of most AI writers that bolted SEO features on after launch. In our 35-hour test, articles produced with SEO.ai needed 40% less manual SEO editing versus drafts from Jasper or Copy.ai. The SEO scaffolding is always present, which is either a feature or a bug depending on your workflow. Our verdict: Best AI-First SEO Writer.
