AI-native code documentation with Gemini chat and diagrams.
CodeWiki, introduced by Google in November 2025, is an AI-native documentation fabric for Google Cloud customers, currently in public preview at codewiki.google. It revolutionizes code documentation by using a Gemini-powered system to scan entire repositories after every commit, regenerating hyperlinked documentation and injecting diagrams to ensure engineers always have current and accurate information. Each CodeWiki page includes a Gemini chat agent that answers natural-language questions using the documentation as context, accelerating onboarding for new contributors, SREs, and auditors. Google is also developing a Gemini CLI extension for local use, extending CodeWiki's automation to private or air-gapped repositories.
- Accelerate onboarding for new contributors by distilling repo intent and dependencies.
- Enable senior developers to rapidly understand unknown libraries through diagrams and hyperlinked docs.
- Ensure continuous synchronization of architecture, class, and sequence diagrams with current code.
- Provide unified natural-language Q&A about the codebase via the Gemini agent.
- Extend automated documentation workflows to private or air-gapped repositories using the Gemini CLI extension.
- CodeWiki automatically scans a repository after each commit to understand code
- assets
- and dependencies. It then regenerates structured wikis (architecture
- guides
- API docs
- dependency maps) to provide current documentation. Users can navigate seamlessly through hyperlinked content that points to specific files
- functions
- or diagram segments. Additionally
- a built-in Gemini chat agent allows users to ask natural-language questions about the codebase
- with answers referencing the updated wiki content.
