What is GitHub Copilot?

Imagine if your code editor could read your mind. That's GitHub Copilot. Built by GitHub and OpenAI, it lives in your IDE and suggests code as you type. It's not just simple autocomplete; it suggests entire functions, complex algorithms, and even unit tests based on the context of your file.

Key Features

Ghost Text: As you type, Copilot suggests the rest of the line or block in gray text. Just hit Tab to accept it.
Copilot Chat: A built-in chat interface where you can ask questions like "How do I center a div?" or "Explain this regex" without leaving your editor.
Multi-Language Mastery: Whether you're writing Python, TypeScript, Go, or Rust, Copilot has seen enough code to be helpful.
Test Generation: Highlight a function and ask Copilot to write tests for it. It's a massive time saver.

Real-World Use Cases

Crushing Boilerplate

Need to write a standard API fetch function or a React component structure? Copilot will often have it written before you finish typing the function name.

Learning New Languages

If you know Python but need to write some Go, Copilot helps bridge the gap by suggesting idiomatic syntax, helping you learn by doing.

Deciphering Legacy Code

Stuck with a messy codebase? Highlight a confusing block and ask Copilot to explain what it does in plain English.

Pricing

Individual: $10/month or $100/year. A small price to pay for the hours saved.
Business: $19/user/month with added enterprise features.
Free: If you are a verified student or a maintainer of a popular open-source project, you might get it for free!

Who Should Use It?

If you write code for a living (or for fun), you should at least try the free trial. It helps you stay in the "flow state" by handling the boring parts of coding, letting you focus on the logic and architecture.
