GitHub Copilot - AI Code Assistants Tool

Overview

GitHub Copilot is an AI pair programmer that provides context-aware code suggestions, snippets and short functions directly inside IDEs and on GitHub. Built by GitHub with large language models, Copilot offers whole-line and multi-line completions, in-line code suggestions, and conversational assistance (Copilot Chat) to accelerate development workflows. According to GitHub documentation, Copilot integrates with common editors and workflows so developers can accept, modify, or reject suggestions without leaving their coding environment. Copilot has evolved into a multi-surface product (IDE extensions, a CLI, and GitHub.com integrations) that supports tasks beyond completion: generating unit tests, explaining code, suggesting fixes, and assisting with pull request changes. Recent product updates expanded conversational capabilities and added tighter pull-request and review assistance. Copilot is designed for many mainstream programming languages (for example: Python, JavaScript/TypeScript, Java, C#, Go, Ruby) and is commonly used for rapid prototyping, boilerplate generation, test scaffolding, and exploratory coding. For additional implementation details and official docs, see the GitHub Copilot feature pages and repository documentation.
