GitHub Copilot is an AI-powered pair programming tool that works directly in your editor, suggesting whole lines or entire functions for you. It uses the OpenAI Codex to suggest code in real-time, and is trained on billions of lines of code, across dozens of programming languages.

This tool helps developers save time by eliminating the need for boilerplate and repetitive code patterns, allowing them to focus on building great software.

All you have to do is write a comment describing the logic you want and Copilot will immediately suggest code to implement the solution. It integrates with other GitHub products such as Actions, Packages, Security, Codespaces, Code Review, Issues, and Discussions.

Copilot Replay enables you to quickly iterate on code, while Copilot Train allows you to customize the tool's models to your specific domain and use case.
