What is Theneo?
The positioning of Theneo's official website is to enable humans to deliver documents together with agents, and to put API references, guides, change logs and private customer portals into the same developer portal. It emphasizes not static publishing, but collaboration between engineers, document writers, product managers and AI agents on the same document. The official stated that it has used its own AI to generate documents as early as 2022, long before the emergence of ChatGPT.
Who is it for?
- SaaS teams that expose APIs externally and need to maintain reference documents long-term.
- Documentation engineers and technical writers who need to keep track of API field changes frequently.
- B2B delivery teams that need to customize document views for different customers.
- Platforms that want to make their own documents readable and usable by AI agents.
