What are GitHub Copilot and Codex?

GitHub Copilot logo
GitHub Copilot

GitHub Copilot is an AI coding assistant built by GitHub that helps you write, understand, and fix code faster. You can type code or ask questions in plain language, and it gives you suggestions right inside your editor. It also has a chat feature where you can ask about your code, get help fixing bugs, or generate tests. Copilot can work on its own too, planning and making changes across many files, running tests, and even opening pull requests for you. It works in popular tools like VS Code, JetBrains IDEs, the terminal, and GitHub.com. There is a free plan, along with paid plans that unlock more models and features for individuals and teams.

Codex

Codex is an AI coding agent from OpenAI that can plan, write, test, and fix code with real autonomy. You describe a task in plain language, and Codex works through your project step by step, running commands, checking tests, and preparing changes for you to review.

It started as a tool for software engineers but has grown into a wider work assistant used by analysts, designers, and other non-technical teams too. Codex runs in isolated spaces, so it does not touch your main project files directly.

You can use it from a desktop app, a command line tool, inside your code editor, or through ChatGPT on the web, and everything stays in sync across each place you work.
