GitHub Copilot is an AI-powered coding assistant developed by GitHub in collaboration with OpenAI.
It helps developers by suggesting code snippets, functions, and even entire blocks of code based on the context of the code you're writing.
Copilot is designed to integrate with popular code editors like Visual Studio Code (VSCode), JetBrains IDEs, and others.
GitHub Copilot is powered by OpenAI's Codex, a machine learning model trained on a massive amount of publicly available code (including repositories from GitHub).
