Theneo

Theneo is an AI-powered API documentation platform trusted by over 15,000 teams ranging from startups to Fortune 500 companies. It provides an all-in-one developer portal where engineering teams, technical writers, and product managers can collaboratively create API references, guides, changelogs, and private customer-facing documentation. The platform has been generating documentation with its own AI since 2022 and emphasizes real-time co-editing and agent-ready outputs through MCP and llms.txt support.

Key Features

• AI-Powered Doc Generation: Theneo can generate complete API documentation from any API specification automatically. Its AI has been trained on API documentation since 2022 and produces Stripe-quality references from OpenAPI, GraphQL, REST, SOAP, Async, and gRPC specs.
• Ask AI: Developers interacting with Theneo-hosted documentation can ask natural language questions and receive precise answers drawn from the documentation. The feature outperforms leading documentation AI tools on benchmarks and eliminates the need to manually search through pages of content.
• Smart Changelogs: The platform automatically detects breaking changes in API specifications and generates changelog entries. This keeps API consumers informed of modifications without manual effort from the documentation team.
• MCP Server and llms.txt Support: Theneo serves documentation through Model Context Protocol (MCP) and llms.txt standards, making API documentation accessible to AI agents and LLM-based development tools. Teams can expose their docs as tools that agents can discover and use.
• Private Customer Portals: Organizations can create authenticated portals where each customer sees only the APIs, SDKs, and guides relevant to them. Features include per-customer login, email invites, SSO, custom branding per segment, and analytics showing which customers engage with which documentation.
• Real-Time Collaboration: Engineers, writers, and product managers can co-edit documentation in real time with full history and reverting. The platform supports preview deployments, versioning, and multi-stage review workflows.

Integrations and Developer Tools

• CI/CD Integration: Theneo connects with GitHub Actions, GitLab, and Bitbucket for automated documentation updates triggered by code changes. It also offers a CLI tool and SDK for programmatic doc management.
• IDE Support: A Visual Studio Code extension allows developers to work with API documentation directly from their editor.
• Postman Sync: Collections defined in Postman can be imported into Theneo to create structured API references.

Security and Compliance

Theneo is SOC 2 Type II and ISO 27001/9001 certified, GDPR compliant, and offers EU data residency. Enterprise customers can self-host the entire platform. Additional security features include custom SSO (SAML/OIDC), custom roles and permissions, IP whitelisting, and full audit logs.

Use Cases

• API-First Companies: Organizations that expose APIs to external developers use Theneo to deliver professional documentation comparable to Stripe or Twilio.
• B2B Platforms and Fintechs: Companies in regulated industries use private customer portals to share API documentation selectively with partners while maintaining security and governance.
• Internal Developer Experience Teams: Platform engineering teams document internal APIs and microservices in private projects, improving developer productivity across the organization.
