NotionCodeMirror: Auto-Generating a Living Code Documentation Workspace in Notion

NotionCodeMirror is a CLI tool that automatically generates a Notion workspace for any GitHub repository, including an overview, architecture page, searchable API reference, and module pages. It keeps the workspace in sync as the code evolves.

Details

NotionCodeMirror is a tool that automates the process of creating and maintaining a living code documentation workspace in Notion. It analyzes a GitHub repository using jcodemunch-mcp, which extracts symbols, ranks them by importance, traces dependencies, and builds class hierarchies. It then hands this structured digest to Claude, an AI language model, which focuses on synthesizing and writing the content for the workspace. This includes an overview page, an architecture page written in natural language, a searchable API reference database, and individual module pages. The tool leverages Notion MCP to directly write this content into the Notion workspace, rather than just generating a text artifact. This allows for features like maintaining the page hierarchy, choosing appropriate icons, and updating existing pages incrementally as the code changes. The end result is a fully navigable and shareable Notion workspace that keeps pace with the evolving codebase.
