Readme

Readme is a platform that lets you create and publish interactive developer documentation for your APIs. Unlike traditional documentation tools, Readme automatically generates API references from your OpenAPI or Swagger files and keeps everything in sync with your code.

The platform includes a built-in editor where you can write guides, add code examples, and explain how your API works. Developers using your API can test endpoints directly from the documentation with the Try It feature, making it easier to understand how everything works.

Readme also provides analytics so you can see which parts of your documentation get the most views and where developers might be getting stuck, helping you improve your API experience over time.

Theneo

Theneo is an AI-native documentation platform that transforms how teams create and manage API documentation. Think of it as having an expert technical writer that works instantly - you provide your API specification files (like OpenAPI, Postman collections, or GraphQL schemas), and Theneo generates complete, interactive documentation automatically.

What makes it special is the AI technology that writes descriptions, creates examples, and organizes everything in a clean, professional format. The result looks like high-quality documentation from companies like Stripe or Twilio, but without the months of work typically required.

Beyond just creating docs, Theneo offers developer portals, real-time collaboration tools, automatic changelog generation, and API testing capabilities. It supports custom branding, so your documentation matches your company's look and feel. The platform handles everything from simple internal API docs to complex public developer portals.
