GitHub Copilot
An AI coding assistant that suggests code completions and can generate whole functions directly inside your code editor, based on the surrounding code and comments.
Best for
Speeding up routine coding tasks, generating boilerplate, and suggesting fixes.
Suitable for
Software developers using editors like VS Code or JetBrains IDEs.
Features
- Inline code suggestions
- Chat-based code assistant
- Test generation
- Multi-file editing support
What you get for free
There is a free tier with a monthly cap on completions and chat messages. Verified students, teachers, and maintainers of popular open-source projects can qualify for full access at no cost. Paid individual and business plans remove the caps.
Where GitHub Copilot falls short
The parts a product page will not tell you.
- It suggests code that looks right and is subtly wrong — plausible function names, plausible arguments, wrong behavior.
- It can reproduce insecure patterns it learned from public code, so security review does not become optional.
- It knows the file you are in far better than it knows your wider codebase or your team's conventions.
- On unfamiliar or heavily proprietary code, suggestion quality drops sharply.
Who should skip it
People still learning to program, where accepting suggestions you cannot evaluate prevents the fundamentals from forming — and any codebase whose license or client agreement restricts AI-assisted code.
Getting started
- 1Install the extension in VS Code, JetBrains, or Neovim and sign in with your GitHub account.
- 2Write a clear comment describing what the next function should do, then let it complete. Its suggestions are only as specific as your description.
- 3Read every suggestion before accepting it. If you would not have written it yourself and cannot explain it, do not keep it.
Our take
Most useful for the code you already know how to write but would rather not type: boilerplate, tests, repetitive transformations, unfamiliar syntax in a familiar language. It saves real time there. It is much weaker as a substitute for understanding, and the developers who get the least out of it are usually the ones trusting it the most.

GitHub Copilot compared with
- Cursor vs GitHub Copilot →One replaces your editor and works across many files at once; the other plugs into the editor you already use. The real difference is how much you have to review.
Prompts that work well in GitHub Copilot
- Explain This Error and Suggest a Fix →Get a plain-English explanation of an error plus a concrete next step, not just a fix.
- Review My Code Like a Senior Developer →Get a structured review of your code covering bugs, readability, and edge cases.
