GitHub Copilot

GitHub Copilot is the AI coding assistant most developers have tried first. It lives inside editors like VS Code, Visual Studio and the JetBrains IDEs, and it suggests whole lines or functions as you type. Because it is built by GitHub and trained with code in mind, it handles everyday boilerplate and common patterns well. Beyond autocomplete, Copilot has a chat panel where you can ask why something breaks, request a refactor, or have it write tests for the file you have open. Its agent mode can take a bigger task, edit several files and run commands, while you watch and approve the changes. It works best when you already know what you want and need to move faster. Individual developers get a free tier with limits, and paid plans for individuals, teams and companies add more requests, model choice and admin controls.
