What SEO Writing tools do
The distinction that matters here is between a general AI writer and an SEO writing tool, and it is not about the quality of the prose. It is whether the product carries the search machinery: keyword data, SERP-derived structure, internal links drawn from your real sitemap, schema, and publishing into your CMS. A general writer produces text you then have to fit into an SEO workflow by hand. What every tool in this category shares is that its output is a first draft: factual errors, stale date context and formatting tics are normal, and shipping unreviewed is how sites get filled with content nobody can defend.

Entry price is the lowest published figure on a plan you could buy on its own, add-ons and extra seats are excluded, and a tool whose vendor publishes no figure sits under “price not published” rather than being guessed at.
