Code Wiki
What is Code Wiki?
Code Wiki is a developer platform developed by Google that addresses the massive cost and time involved in reading existing code. Instead of relying on static files, it maintains a continuously updated, structured wiki for ingested GitHub repositories. The AI system scans the codebase and regenerates documentation, architecture diagrams, and sequence diagrams after each code change. Additionally, it integrates a Gemini-powered chat agent that acts as a repository expert, instantly bridging the gap between manual document reading and exploring actual code files.
How to use Code Wiki?
To use Code Wiki effectively, visit the website and submit the link to a public GitHub repository. The platform will automatically ingest the codebase and generate interactive, up-to-date documentation, class diagrams, and sequence flows. Once generated, you can navigate high-level architectural concepts or use the built-in Gemini chat to ask context-aware questions about the code, instantly jumping directly to the relevant files and functions via hyperlinks.
