Codewiki

What is Codewiki?

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.

How to use Codewiki?

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.
