Introduction

Writing code has never been more collaborative—even when you’re working alone. GitHub Copilot, the AI coding assistant built into the tools millions of developers already use, has fundamentally changed how software gets written. In this GitHub Copilot review, we examine what makes it tick, how much it costs, and whether it’s still the best AI assistant for developers in 2025.

What Is GitHub Copilot?

GitHub Copilot is an AI-powered coding assistant developed by GitHub (a Microsoft subsidiary) in collaboration with OpenAI. It’s available as an extension for VS Code, JetBrains IDEs, Neovim, and Visual Studio, and integrates directly into the GitHub web interface. Copilot uses OpenAI Codex and GPT-4 to suggest code completions, entire functions, and documentation in real time as you type.

Key Features

  • Inline Code Suggestions: Copilot reads your context and suggests complete lines or blocks of code as you type.
  • Copilot Chat: A conversational AI assistant embedded in your IDE—ask it to explain code, debug errors, or refactor functions.
  • GitHub.com Integration: Use Copilot on pull requests, issues, and the GitHub web editor.
  • Multi-Language Support: Works with Python, JavaScript, TypeScript, Ruby, Go, C#, C++, PHP, and dozens more.
  • Unit Test Generation: Ask Copilot to generate test cases for existing functions automatically.
  • Code Explanation: Highlight any code block and ask Copilot to explain it in plain English.
  • Security Vulnerability Detection: Copilot flags potential security issues as you code.
  • CLI Integration: GitHub Copilot CLI helps you write and explain terminal commands.
