Copilot monitors the code file currently being edited and the surrounding context, then generates inline suggestions for the next line, function, or block of code. Developers accept suggestions using a keyboard shortcut or dismiss them and continue typing. Copilot Chat allows developers to ask questions, request explanations, or get refactoring suggestions in a conversational panel within the editor. All processing is handled remotely via GitHub's API.
GitHub Copilot
GitHub Copilot is an AI coding assistant developed by GitHub in collaboration with OpenAI. It is built on a large language model trained on publicly available code and is designed to assist developers with code generation, completion, explanation, and refactoring directly within their development environment.
Copilot integrates as an extension into popular code editors including Visual Studio Code, JetBrains IDEs, Neovim, and others. It provides inline suggestions as the developer types, making it a low-interruption addition to existing coding workflows.
It is one of the most widely adopted AI coding tools among professional software developers, with usage across individual developers, small teams, and enterprise engineering organisations. GitHub (owned by Microsoft) has since expanded the product with Copilot Chat, Copilot in the CLI, and enterprise workspace features.

Pros & Cons
Pros
- Deep IDE integration with minimal workflow disruption
- Supports a wide range of programming languages
- Backed by GitHub and Microsoft infrastructure
- Effective at common patterns and boilerplate
- Copilot Chat adds conversational command without leaving the editor
Cons
- Suggestions can be incorrect or insecure and require review
- Requires active internet connection
- May suggest code derived from public repositories (licence considerations)
- Less effective at highly domain-specific or proprietary codebases
- Subscription cost may not be justified for occasional coders
Pricing
GitHub Copilot Individual is available as a monthly or annual subscription. Copilot Business and Enterprise plans offer additional team management, policy controls, and security features at higher per-seat pricing. GitHub provides a free plan for verified students and open source maintainers. A limited free tier was also introduced for individual developers with capped monthly completions.
How It Compares
GitHub Copilot is most directly compared to Tabnine, Codeium, Cursor, and Amazon CodeWhisperer. Tabnine and Codeium offer local-model options for privacy-sensitive teams. Cursor extends Copilot-style features into a standalone code editor with deeper AI integration. CodeWhisperer is tightly integrated with AWS services. Copilot's main advantage remains its GitHub ecosystem integration and model quality backed by OpenAI.
