Automated repository documentation
A specialized AI agent analyzes repository source code and generates natural-language summaries, so readers can get oriented without manually writing or maintaining docs.
Code Wiki
RivendicaCode Wiki is an AI-powered documentation hub for code repositories with summaries, architecture diagrams, and repo Q&A to help developers navigate codebases faster.
Overview
Code Wiki is an AI-powered documentation hub for code repositories. It analyzes source code and generates natural-language summaries, architectural diagrams, and other repository insights to help developers understand a codebase faster.
The product also includes a conversational “Ask about this repo” experience that uses the generated wiki content as its primary context. That makes it useful both for initial onboarding and for follow-up questions about structure, behavior, and repository details.
Features
Generated architecture diagrams
The wiki includes architectural diagrams that show relationships, hierarchies, and dependencies in the codebase, with interactive viewing for zooming and panning.
Repo Q&A chat
A conversational experience lets users ask questions about a repository using the wiki content as the main context source.
Repository discovery and access
Search lets you look up a repository by name from the homepage, and a direct URL format also points from a repository page to its wiki.
Ongoing content refresh
Wikis refresh periodically rather than staying static, so the generated documentation is updated over time as the source repository changes.
Auto-managed wiki pages
Public wiki pages are read-only and do not accept direct edits or pull requests, which keeps the generated documentation aligned to the source repository.
Use Cases
Onboarding to a new codebase
A developer joining a new repository can use the generated summaries and diagrams to understand the structure of the codebase before opening the source in detail.
Repository Q&A
A team can use the wiki as a reference when they need quick answers about a repository instead of searching through files manually.
Codebase exploration
Someone evaluating a public open-source project can browse the wiki to get a higher-level view of architecture and key components before reading the full code.
Keeping docs current
A repository owner can rely on periodically refreshed documentation to keep generated content aligned with source changes without maintaining a separate manual docs process.
Pros and Cons
Pros
- Generates documentation automatically from repository source code.
- Surfaces architecture through diagrams as well as text summaries.
- Supports a repository-specific chat workflow for targeted questions.
- Public open-source repositories on the site are available free of charge.
- Keeps documentation aligned to the source because direct edits and pull requests are not accepted.
Cons
- It currently supports GitHub repositories only.
- Wikis are updated periodically rather than continuously, so freshness can vary by project.
- The FAQ says the chat assistant may make mistakes, so code and answers should still be reviewed and verified.

What is Code Wiki?
Code Wiki is an AI-powered documentation hub for a code repository. It analyzes source code to generate summaries, architectural diagrams, and other repository insights, and it supports a chat experience for asking questions about the repo.
How is Code Wiki related to Gemini?
Code Wiki is built on Google’s Gemini models. The FAQ says a specialized AI agent uses Gemini to analyze source code and generate the wiki content, and the chat experience is also powered by Gemini using the wiki as context.
Is Code Wiki free to use?
Public Code Wikis for open-source repositories on codewiki.google are free.
What code hosting platforms are supported?
Code Wiki currently supports repositories hosted on GitHub only. The FAQ says support for other platforms such as GitLab and Bitbucket is planned for the future.
How current is the documentation?
Wikis are updated periodically, with refresh timing varying by project based on popularity, usage, and other factors. The FAQ also notes that the last generated date appears at the bottom left of the page.
