About AI API Documentation Generator
API documentation is what turns a working endpoint into something other developers can actually use, but keeping it written and current is a chore most teams put off. The AI API Documentation Generator helps you turn code or endpoint details into readable docs, so consumers know what to send and what to expect back.
Paste your code or describe your endpoints, and the tool drafts documentation covering things like methods, parameters, and responses. It works in the browser for free with no signup, so you can generate a first version quickly. Review it carefully against your actual implementation, since the docs are only as accurate as the input and your API is the source of truth.
Common uses
- Drafting reference docs for a new REST endpoint before you publish it
- Documenting request parameters and response shapes for internal APIs
- Generating a readable starting point for a public API you're about to release
- Filling documentation gaps for endpoints that were never written up
- Producing consistent doc formatting across several endpoints at once

FAQ
What input gives the best results?
Provide the actual handler code or a clear description of each endpoint, including methods, parameters, and sample responses. More detail produces more accurate docs.
Does it generate OpenAPI or Swagger specs?
It focuses on human-readable documentation rather than a formal machine spec. If you need OpenAPI YAML, use the output as a reference and verify the structure separately.
Will the docs match my live API?
Only if your input matches your implementation. Always check generated docs against your real endpoints, since the code is the source of truth, not the description.
Can I use AI API Documentation Generator on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
