The tools, one by one
1.SearchBlueprint
Our productBest for: Planning the work before anything gets written.
A planning tool, not a writer: one run on your URL gives you a keyword map (which page targets which search), a site structure and a list of pages to write next. On paid plans the on-page plan suggests titles and headings for each page, and the free tools score how ready a page is to be quoted by AI search.
Writing opens to customers in October.

Questions people ask
What is an AI SEO tool?
Software that uses AI for part of the SEO work: planning what to publish, writing or optimizing drafts, changing pages on your site, or checking how AI answers mention you. Most tools do one or two of these well.
Will AI-written content hurt my rankings?
Google's guidance asks why content was made: content made mainly to help people is what its systems reward, and using AI mainly to manipulate rankings breaks its spam policies. Plan pages people need and check every draft before it goes live.
Can one tool do everything?
The suites come closest, at a higher price. Many small teams pair a planning tool with one writing tool instead.
Does SearchBlueprint write articles?
Not for customers yet. Writing and publishing open to customers in October; today it plans the pages, writes the on-page titles and headings on paid plans, and gives you the free AI search tools.
Before you pick a tool, see what your own site needs.
Start with the plan for your own site: which page targets each search, and what to write next. The first one is free.
