About Theneo
Theneo is a commercial platform for creating API documentation. It takes API definitions and helps teams turn them into readable reference pages and guides, using AI assistance for drafting and polishing text, and publishes the result as a developer portal.
Theneo is a proprietary, vendor-hosted service. Detailed features, supported spec formats, customization options and plans are described on the vendor's own site, and it suits API teams that want polished documentation without a large technical-writing effort.
