What SemanticOS is
SemanticOS is a web tool that turns a domain into an entity-based topical map of pillar, cluster, and supporting pages. Maps include search intents, URL paths, and internal links. It generates semantic SEO briefs with H2 and H3 outlines, entities to cover, and questions for each map node. The site describes 87 tools, including entity drift analysis, cannibalization detection, and topical gap analysis. Search intent, topic coverage, and entity analysis are part of the workflow, along with CMS publishing. 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; Anthropic bills AI usage, and SemanticOS lists no generation cap. Two hours of free access are available without a card, while a $7.00 trial provides seven days of Starter access. Paid plans start at 59.00 USD monthly.
