About Code Wiki
Code Wiki is a Google tool that automatically generates and maintains documentation for code repositories. Users connect a public repository, and the tool produces hyperlinked documentation, architecture diagrams, and class relationship overviews that update after every commit. A built-in Gemini chat agent allows users to ask natural-language questions about the codebase, receiving responses with direct hyperlinks to relevant files and code sections. The tool replaces manually written markdown files that often become outdated, ensuring documentation always reflects the current state of the code. It is currently available in public preview for open-source repositories via the web interface, with a waitlist for Google’s upcoming Gemini CLI extension for private and internal repositories. Code Wiki is designed for software developers, open-source maintainers, engineering managers, and new team members joining a project, streamlining onboarding and code exploration.
