What Is Theneo

Theneo is an AI-powered platform for generating and maintaining API documentation. Founded around 2021 by Maria Doliashvili and Ana Robakidze and backed by Y Combinator's Winter 2022 batch, the company is headquartered in San Francisco with much of its engineering team based in Tbilisi, Georgia.

The product is built for teams that need Stripe-quality developer docs without dedicating a full-time technical writer to the job, connecting directly to a codebase or API spec to detect changes and keep documentation accurate over time rather than treating docs as a one-time export.

Key Features

Theneo supports essentially every major API spec format, including OpenAPI/Swagger 2.0 and 3.x, Postman collections, GraphQL SDL and introspection, gRPC proto files, SOAP/WSDL and AsyncAPI, so teams can bring documentation in from whatever tooling they already use. Its AI features generate readable descriptions and examples, detect when documentation has drifted from the live API, and power an AI-assisted search experience for readers.

For teams selling APIs to other businesses, Theneo offers authenticated developer-hub portals where each customer signs in, with per-customer logins, email invites and SSO if needed, and sees only the APIs, guides and SDKs relevant to them. An interactive API Explorer lets readers test endpoints directly from the documentation, and automatic changelog generation keeps a record of what changed and when.

Pricing

Theneo's Starter plan is free and includes one public project, two private projects, and capped usage of its AI documentation builder and search features, making it usable for small or early-stage API projects.

Paid plans scale by workspace: Business costs 120 dollars per month billed annually or 150 dollars month-to-month and adds more projects, custom branding, a custom domain and a developer hub; Growth costs 400 dollars per month annually or 450 dollars monthly and adds multiple developer hubs, custom CSS and advanced security controls; and Enterprise is custom-priced, adding self-hosting, SAML SSO, OAuth 2.0 and custom user roles for large organizations.
