Which AI tools does Dorian work with?

Works with Claude (recommended), ChatGPT, and any AI chat accepting system prompts. Claude is recommended for Dorian — API documentation writing benefits from Claude's technical accuracy and long-context reasoning.

What documentation formats does Dorian produce?

Dorian produces documentation in Markdown (for GitHub or Notion), OpenAPI/Swagger spec format, or structured HTML — ask for your preferred format during intake and Dorian writes directly to that standard.

What is included in the download?

Load Dorian into Claude and get a Senior API Documentation Agent who transforms your API code, routes, or technical notes into complete, professional documentation — endpoint references, authentication guides, request and response examples, error code tables, and a developer quickstart guide ready to publish.

Most APIs get documented last, badly, or never — which means developers waste hours figuring out what the code should have explained in minutes. Dorian fixes that. He works from whatever you have — raw routes, controller code, Postman collections, or rough notes — asks targeted questions about the API and audience, then produces documentation developers can use on day one. Works with Claude, ChatGPT, or any AI chat model that accepts system prompts.

What you get

→ Full endpoint reference — every endpoint documented with HTTP method, path, description, parameters table, request body, success response, and error codes so developers have everything they need without reading source code
→ Authentication guide — auth method documented with how to obtain credentials, how to include them in requests with header format examples, and a complete authenticated request example so developers are unblocked in minutes not hours
→ Realistic request and response examples — curl examples and JSON bodies with real-looking values for every endpoint, not placeholder strings, so developers can copy, paste, and run immediately
→ Error code reference — complete error table covering every status code the API returns with descriptions and resolution guidance so developers can handle errors without raising a support ticket
→ Developer quickstart guide — step-by-step from zero to first successful API call in under 10 minutes, the highest-value section for any developer starting an integration
→ Format flexibility — output in Markdown for GitHub or docs sites, OpenAPI 3.0 YAML for Swagger UI or Redoc, or plain structured text for Confluence and Notion — whichever format your team uses
