Asking GitHub Copilot questions in GitHub Mobile

Limitations

The following limitations apply to Copilot Chat in GitHub Mobile:

• If you're a member of an organization, your access to Copilot Chat in GitHub Mobile may depend on policies set by your administrator. See GitHub Copilot policies to control availability of features and models.
• If you reach your premium request limit on mobile, Copilot will automatically fall back to a free, non-premium model. Your access to premium models will reset at the start of the next billing cycle.

Asking a general question about software development

1. In GitHub Mobile, tap the icon in the bottom right corner of the screen.

   Note

   The icon is not shown on every page in GitHub Mobile. If you don't see the icon, navigate to a different page in GitHub Mobile and look for the icon there.

2. At the bottom of the page, in the "Ask Copilot" box, type a question and send the message.

   Some examples of general questions you could ask are:

   • What are the advantages of the Go programming language?
   • What is Agile software development?
   • What is the most popular JavaScript framework?
   • Give me some examples of regular expressions.
   • Write a bash script to output today's date.

3. Within a conversation thread, you can ask follow-up questions. Copilot will answer within the context of the conversation.

Asking exploratory questions about a repository

You can ask questions about a specific repository, to get help with understanding the code, or to get help with a specific task you're working on.

1. In GitHub Mobile, navigate to a repository, and tap the icon in the bottom right corner of the screen.

2. At the bottom of the page, use the "Ask Copilot" box, type a question and send the message.

   For example, if you chose the repository you are working in as the context, you could ask:

   • What is the main purpose of this repo? What problem does it solve or what functionality does it provide?
   • What web frameworks are used in this project?
   • Where is rate limiting implemented in our API?
   • How is the code organized? Explain the project architecture.
   • Are there any specific environment requirements for working on this project?

Asking questions about specific pieces of code

You can chat with Copilot about a file in your repository, or about specific lines of code within a file.

1. In GitHub Mobile, navigate to a repository and open a file.

2. Do one of the following:

   • To ask a question about the entire file, tap the Copilot icon () in the bottom right corner of the file view.
   • To ask a question about specific lines within the file, select and copy the lines you want to ask about. Then tap the Copilot icon () and paste the copied lines in the Copilot Chat input field.

3. Type a question in the "Ask Copilot" box at the bottom of the chat panel and send the message.
