Description The API Documentation Generator transforms your API information into polished, professional documentation that developers actually want to read. Supports REST, GraphQL, gRPC, and WebSocket APIs with multiple output formats including OpenAPI spec, Markdown, and HTML. Includes authentication setup guides, rate limiting details, versioning notes, and real-world request/response examples. The README Generator creates polished, developer-friendly README files that make your project stand out on GitHub. From minimal single-page docs to enterprise-grade documentation with badges, table of contents, installation instructions, configuration guides, API references, architecture diagrams, and contributing guidelines — tailored to your project type, language, and audience.

Use Cases

Pro Tips
  • Include real field names and data types in your input — the generator produces much better docs when it knows your actual schema.
  • Paste your route definitions or controller code directly; the AI can extract endpoints, parameters, and response shapes automatically.
  • For OpenAPI output, the generated spec can be imported directly into Swagger UI, Redoc, or Stoplight for interactive documentation.
  • Include specific feature names and code examples in your project description — the more detail you provide, the more accurate the generated README will be.
  • Use 'Shields.io' badges for open-source projects — they show professionalism and provide at-a-glance project health information.
  • For libraries, the API Reference section is critical. Include your main class/function names and parameters in the project description.
