CodeWiki
AI-powered automated documentation with Gemini chat and diagrams
What is CodeWiki? Complete Overview
CodeWiki is an AI-native documentation system powered by Google's Gemini. It continuously scans repositories after every commit to generate up-to-date documentation, interactive diagrams, and provides a Gemini-powered chat interface for natural language Q&A. The system dramatically reduces the time needed to understand new codebases, with new contributors able to make their first commit on Day 1 and senior developers understanding new libraries in minutes. CodeWiki is currently in public preview for public repositories, with a Gemini CLI extension available for private repositories through a waitlist. The platform combines documentation generation, code navigation, and AI assistance into a unified interface that helps teams maintain accurate, current documentation automatically.

What Can CodeWiki Do? Key Features
Automated Documentation Generation
CodeWiki automatically scans repositories after every commit to generate comprehensive, structured documentation. This includes architecture overviews, API documentation, and dependency maps, all kept perfectly synchronized with the current code state.
Gemini-Powered Chat
Each documentation page includes a Gemini chat agent that can answer questions about the codebase using the current documentation as context. This allows for natural language queries about the repository's functionality and design.
Interactive Diagrams
The system generates architecture, class, and sequence diagrams that automatically update with code changes. These diagrams are fully interactive, linking directly to the relevant code sections they represent.
Deep Code Navigation
Every element in the documentation is hyperlinked to its corresponding code location, allowing seamless movement between documentation and implementation. This includes functions, classes, dependencies, and architectural components.
Private Repository Support
Through the Gemini CLI extension (currently in waitlist), teams can use CodeWiki's capabilities with private or air-gapped repositories, bringing the same automated documentation benefits to proprietary codebases.
Best CodeWiki Use Cases & Applications
Onboarding New Team Members
New developers can quickly understand complex codebases by exploring automatically generated documentation and asking questions through the Gemini chat interface, significantly reducing ramp-up time.
Codebase Audits and Reviews
Teams can efficiently review unfamiliar code by navigating through automatically generated architecture diagrams and documentation that accurately reflects the current implementation.
Maintaining Documentation
Development teams can eliminate documentation debt by using CodeWiki to automatically keep all technical documentation perfectly synchronized with code changes.
Open Source Contribution
Open source maintainers can provide contributors with always-accurate documentation, reducing the barrier to entry for new contributors and decreasing the number of basic questions maintainers need to answer.
How to Use CodeWiki: Step-by-Step Guide
Connect your repository to CodeWiki by granting access to your GitHub, GitLab, or other version control system where your code is hosted.
CodeWiki will perform an initial scan of your entire repository, generating comprehensive documentation including architecture diagrams and API references.
As you continue development, CodeWiki will automatically update the documentation after each commit, ensuring it always reflects the current state of your code.
Use the interactive documentation interface to explore the codebase, jumping between documentation and implementation via the embedded links.
Ask questions about the code in natural language using the built-in Gemini chat interface, which provides answers based on the current documentation.
For private repositories, download and configure the Gemini CLI extension to bring CodeWiki's capabilities to your internal codebase (available through waitlist).
