Ask HN: How to generate product docs E2E?

I have an existing handwritten knowledgebase with screenshots of an app, a codebase with standard CI/CD pipelines, and an API whose docs are autogenerated against an OpenAPI spec.

Is there a convenient way these days to chain software together so that product documentation, including screenshots, is completely autogenerated on new codebase commits? Anyone tried some chain of tools, including paid ones, that works successfully in the wild?
