What is GitHub Copilot?
GitHub Copilot is an AI-powered code completion tool that acts as an "AI pair programmer." Developed by GitHub and OpenAI, it assists developers by suggesting code snippets, entire functions, and even complex algorithms directly within their IDEs as they type.
Copilot learns from billions of lines of public code to provide context-aware suggestions, helping developers write code faster, reduce boilerplate, and explore new approaches. It supports a wide range of programming languages and frameworks, making it a versatile tool for modern software development.
Key Features
- Real-time Code Suggestions: Provides suggestions for lines of code or entire functions as you type.
- Context-Aware: Understands the context of your current file and project to offer relevant suggestions.
- Multi-Language Support: Works with many popular programming languages including Python, JavaScript, TypeScript, Ruby, Go, Java, C++, and C#.
- Code Generation: Can generate boilerplate code, tests, and even complex algorithms based on comments or function signatures.
- IDE Integration: Available as extensions for popular IDEs like Visual Studio Code, Visual Studio, Neovim, and JetBrains IDEs.
Pricing
Copilot offers different plans for individuals and businesses:
- Copilot Individual: $10/month or $100/year. Access for one developer.
- Copilot Business: $19/user/month (or $190/user/year). Includes organizational policy management, license assignment, and provides code suggestions that are more likely to be relevant to your organization's codebase while offering improved privacy.
- Copilot Enterprise: $39/user/month (or $390/user/year). Adds context from your organization's repositories for even more relevant suggestions.
