What SemanticOS is
SemanticOS is a paid web platform that turns a domain into an entity-based topical map. It organizes pillar, cluster and supporting pages with search intents, URL paths and internal links, then generates semantic SEO briefs containing H2/H3 outlines, entities and questions for each map node. The site describes 87 tools, including entity drift analysis, cannibalization detection and topical gap analysis. Pro and higher plans list CSV, XLSX, JSON, Markdown and PDF exports. Users can import keyword lists from Ahrefs or Semrush, bring in Search Console data and connect DataForSEO for search volumes. Every plan uses the customer’s Claude API key, with Anthropic usage billed separately and no SemanticOS generation cap. Two hours of free access are offered without a credit card; a $7 trial gives seven days of Starter access for one project.
