Why teams use this tool
API docs stay maintainable when endpoint narratives live beside the code that changes.
Endpoint clarity
Readers find verbs, paths, and schemas in predictable order—critical for partner APIs.
Examples beside prose
Keep request and response samples adjacent to explanations so developers trust the contract.
Export-ready formatting
Copy clean Markdown or HTML previews for static sites and internal handoffs.
How it works
- 1
Choose the sections you need for your API surface.

Preview and copy Markdown or HTML for your portal.
From scattered notes to navigable API reference
GET /users - returns users. POST /login - auth.
## GET /users
Fetch all users.
### Response
```json
{ "id": 1 }
```
