Theneo
API documentation and developer portal platform with AI-generated docs, Ask AI search, changelogs and an MCP server.
Theneo is a platform for creating and hosting API documentation and developer portals. Theneo generates reference docs from an API specification with its own AI, lets engineers, writers and AI agents co-edit in real time, publishes changelogs that flag breaking changes, and exposes the docs to AI tools through an MCP server and llms.txt.
Best for API teams that want generated, collaboratively edited documentation and customer-specific developer portals that AI agents can also read.

What is Theneo?
Theneo is a platform for writing, generating and hosting API documentation and developer portals. It produces reference docs from an API specification using its own AI, which the company says it has been building since 2022, and covers API references, user guides, changelogs and private customer portals in one place. Engineers, writers, product managers and AI agents edit the same document in real time, with a Markdown mode and a visual editor, comments, version history and rollback. An Ask AI assistant answers readers' questions from the docs, changelogs flag breaking changes automatically, and an MCP server together with llms.txt makes the content usable by AI tools. Private portals show each signed-in customer only the APIs that apply to them. Supported formats include REST, AsyncAPI, SOAP, GraphQL and gRPC.
Key Features
AI Doc Generation
Builds complete reference documentation from an uploaded API specification.
Ask AI
Gives developers reading the docs a direct answer to a question rather than a list of search hits.
Automated Changelogs
Generates release notes when an API changes and marks changes that would break existing integrations.
Real-Time Co-Editing
Shows live cursors and presence so several people edit one page together, in Markdown or a WYSIWYG view.
Private Customer Portals
Creates authenticated, branded portals in which each customer sees only the APIs, guides and SDKs relevant to them.
MCP Server and llms.txt
Publishes documentation in forms that AI agents and coding assistants can query as tools.
Use Cases
- Public API Reference
- A startup turns its OpenAPI file into a hosted reference with a playground and code samples.
- Partner-Specific Docs
- A fintech gives each partner a login that reveals only the endpoints they have purchased.
- Keeping Docs in Sync
- A team connects GitHub so documentation updates when the specification changes.
- Agent-Ready Documentation
- A platform exposes its docs over MCP so coding assistants can look up endpoints.
- Regulated Deployments
- An enterprise self-hosts the portal and adds SAML single sign-on and custom roles.
Things to know
