Automatically create and maintain technical documentation by analyzing code repositories, collaboratively reviewing content, and publishing polished docs.

Workflow Steps

1

GitHub

Trigger documentation generation

Set up a webhook that triggers when code is pushed to main branch. Use GitHub Actions to analyze repository structure, README files, and code comments to extract documentation requirements.

2

OpenAI Codex

Generate structured documentation

Process the code analysis through Codex API to automatically generate API documentation, function descriptions, and usage examples. Format output as structured markdown with consistent sections for overview, parameters, examples, and notes.

3

Notion

Create review workspace

Automatically create a new page in your team's documentation database with the generated content. Set up review assignments for technical writers and subject matter experts, with due dates and approval workflows.

4

GitBook

Publish approved documentation

Once approved in Notion, automatically sync the finalized documentation to GitBook using their API. Maintain version control and update the public documentation site with new content and structural changes.
