Theneo was built around a specific pain point: API docs that drift out of sync with the product because engineers export a spec, writers paste it into a docs tool, the API changes again, and nobody updates anything. Its answer is a single collaborative surface where humans and AI agents edit the same document at the same time, backed by AI that generates complete references from specs and keeps changelogs current with automatic breaking-change detection.
Beyond generation, Theneo is a full developer-portal builder. It supports REST, AsyncAPI, SOAP, GraphQL, and gRPC, offers a versioned API playground and code generation, and can export projects back to OpenAPI or Markdown. Branding controls include custom domains, global CSS/JS, and developer-portal templates, while access controls cover private endpoints, company and user management, and guest or external customer access.
For the AI era, Theneo ships an MCP server and llms.txt-ready output so agents can consume your docs as tools, and it remains a market leader among docs AI on benchmarks. It reports more than 18,000 companies using the platform, is SOC 2 Type II, ISO 27001 and 9001 certified and GDPR compliant, and serves B2B platforms, fintechs, and regulated industries where a single public docs site isn't enough.
