About knowledge bases

Organization owners can create knowledge bases, bringing together Markdown documentation across one or more repositories. Organization members can then specify that knowledge base as the context for Copilot Chat in GitHub.com, Copilot Chat in Visual Studio Code, and Copilot Chat in Visual Studio.

When you ask a question in GitHub Copilot Chat with a knowledge base selected, GitHub Copilot will search the knowledge base for relevant information and synthesize a response.

For more information on how to use knowledge bases in Copilot Chat, see "Asking GitHub Copilot questions in GitHub.com" and "Asking GitHub Copilot questions in your IDE."

Creating a knowledge base

You can create a knowledge base from a single repository or a selection of repositories. You can create a knowledge base using public, private, and/or internal repositories.

Knowledge bases you create will be accessible by all organization members with a GitHub Copilot Enterprise subscription. When an organization member uses a knowledge base as context in GitHub Copilot Chat, the response will only use data from repositories that the organization member has read access to.
