What is GitHub Copilot?
GitHub Copilot is an AI pair programmer that integrates into your existing code editor (VS Code, JetBrains, Neovim, etc.) to provide intelligent code suggestions. It's built on OpenAI's Codex model and trained on billions of lines of public code.
Launched in 2022, Copilot has become the most widely adopted AI coding tool, with millions of developers and enterprise customers. If you're working at a company, there's a good chance Copilot is already approved and available.
Key Features
Inline Completions
Copilot's bread and butter. As you type, it suggests entire lines or blocks of code based on context. The suggestions are often surprisingly accurate, especially for boilerplate code, tests, and common patterns.
Copilot Chat
An AI assistant integrated into your IDE. Ask questions about your code, get explanations, or request refactoring suggestions. It's not as powerful as Cursor's codebase-aware chat, but it's convenient and fast.
Multi-IDE Support
Unlike Cursor (which is VS Code only), Copilot works in VS Code, JetBrains IDEs (IntelliJ, PyCharm, etc.), Neovim, and even Visual Studio. This matters if your team uses different editors.
GitHub Integration
Deep integration with GitHub for pull request summaries, code review assistance, and documentation generation. The enterprise features around security scanning are also mature.
✓ Pros
- Excellent autocomplete — feels natural
- Works in any major IDE
- Enterprise-ready with security features
- Easier to get approved at companies
- Strong GitHub/Microsoft ecosystem
- 30-day free trial, cheap for students
✗ Cons
- No multi-file editing like Cursor
- Chat is less powerful than competitors
- Limited model choice (no Claude)
- Can suggest outdated patterns
- Privacy concerns with code telemetry
Who Should Use GitHub Copilot?
Ideal For:
- Enterprise developers — Already approved at most companies
- JetBrains users — Best AI option for IntelliJ/PyCharm
- Teams with mixed editors — Everyone can use the same tool
- Students — Free with GitHub Education
- Developers focused on autocomplete — The inline suggestions are top-tier
Maybe Not For:
- AI/LLM developers — Cursor's multi-file editing is better for AI apps
- Developers who want Claude — Copilot is OpenAI-only
- Those doing major refactors — Cursor's Composer is superior
Our Verdict
GitHub Copilot is the safe, solid choice. It won't blow your mind like Cursor's Composer feature, but it will make you measurably faster at writing code. The autocomplete is excellent, and the multi-IDE support makes it practical for teams.
If you're at a company where Copilot is already available, use it. If you're choosing for yourself and doing a lot of AI/LLM development, consider Cursor instead.
