GitHub Copilot
AI Pair Programmer Built Into Your Editor
What is GitHub Copilot?
GitHub Copilot is GitHub's AI coding assistant for code completion, chat, code review, pull request help, and agentic development workflows across GitHub.com, VS Code, Visual Studio, JetBrains IDEs, Neovim, and GitHub Mobile. Copilot includes a limited Free tier for individual developers, paid Pro and Pro+ plans for heavier individual usage, and Business and Enterprise plans for organizations that need policy controls, IP indemnity, private codebase context, and GitHub.com integration. Copilot is powered by generative AI models from GitHub, OpenAI, Microsoft, and other supported providers depending on feature and plan.
Key Features of GitHub Copilot
Inline Code Completion
GitHub Copilot suggests multi-line completions as you type, anticipating the next function or block. Press Tab to accept, or cycle through alternative GitHub Copilot suggestions until one matches your intent perfectly.
Copilot Chat
Ask GitHub Copilot questions about your code in a sidebar chat. Request explanations, generate tests, refactor selections, or debug errors. Copilot Chat understands the file you have open and your selected code.
Slash Commands
Use commands like /tests, /fix, /explain, and /doc inside GitHub Copilot Chat to trigger specialized workflows. These shortcuts let GitHub Copilot generate test suites or write documentation without long prompts.
Multi-File Edits with Workspaces
GitHub Copilot's @workspace agent reasons about your entire repository. Ask about architecture, request changes spanning multiple files, and Copilot will plan and apply coordinated edits across the codebase.
Pull Request Summaries
On GitHub.com, Copilot drafts PR descriptions from your diff, suggests reviewers, and answers questions about changes. This makes code review faster for both authors and reviewers using GitHub Copilot.
Broad IDE Support
GitHub Copilot runs in VS Code, Visual Studio, all JetBrains IDEs, Neovim, Xcode, and Azure Data Studio. Settings sync across editors, so your Copilot experience stays consistent everywhere.

Best Use Cases for GitHub Copilot
Writing Repetitive Boilerplate
- Target user:
- Backend engineer building REST endpoints
- Pain point:
- Typing the same controller, validator, and DTO patterns for every new route burns 30 minutes per endpoint
- Solution:
- GitHub Copilot infers the pattern from one example and generates the rest in seconds. A comment like // POST /users yields a complete handler.
Generating Unit Tests
- Target user:
- Mid-level developer with low test coverage
- Pain point:
- Writing tests for existing untested code feels like a chore and gets deprioritized
- Solution:
- Select a function, run /tests in GitHub Copilot Chat, and get a working test suite with edge cases. Coverage climbs from 30% to 80% in an afternoon.
Learning an Unfamiliar Codebase
- Target user:
- New hire onboarding to a large monorepo
- Pain point:
- Tracing how a feature works across 50 files takes days of grep and Slack messages
- Solution:
- Ask @workspace in Copilot Chat how authentication flows through the app. GitHub Copilot summarizes the path and links to the relevant files.
Translating Between Languages
- Target user:
- Engineer porting a Python script to Go
- Pain point:
- Manual translation introduces subtle bugs and takes hours per file
- Solution:
- Paste the Python into Copilot Chat and ask for an idiomatic Go version. GitHub Copilot preserves logic while applying language-appropriate patterns.
