Theneo automates the creation of professional API documentation that matches the quality standards set by companies like Stripe and Twilio. The AI engine ingests OpenAPI specifications, Postman collections, GraphQL schemas, or raw source code and generates complete developer portals with interactive endpoints, request-response examples, authentication guides, and error code references in a visually polished format.
The generated documentation includes interactive API playgrounds where developers can test endpoints directly from the docs, multi-language code snippets that automatically adapt to the reader's preferred programming language, and versioning support that tracks API changes over time. Teams can customize the look and feel with branded themes, custom domains, and layout options while the AI handles content generation.
As a Y Combinator alumnus, Theneo has established a strong presence in the API development niche. The freemium model provides a generous starting point for individual developers and small teams, with paid tiers adding team collaboration, custom domains, and advanced analytics on documentation usage. The platform integrates with GitHub for automated documentation updates when API code changes are pushed.
