Definition

GitHub Copilot is an AI-powered coding assistant, built by GitHub in partnership with OpenAI, that suggests code completions, whole functions, and chat-based help directly inside a developer's editor.

Overview

GitHub Copilot works as an inline pair-programmer: as a developer types, it suggests completions ranging from a single line to an entire function, based on the surrounding code, comments, and open files in the project. It runs as an extension inside editors like VS Code, offering suggestions that a developer can accept, modify, or ignore. Beyond autocomplete, Copilot includes a chat interface for asking questions about a codebase, explaining unfamiliar code, generating tests, and proposing fixes for bugs or failing builds, and it can operate across an entire repository's context rather than just the currently open file. Enterprise and business tiers add code-referencing controls and organizational policy management. Copilot has become one of the most widely adopted AI coding tools, competing with alternatives like Cursor and Amazon's coding assistants, and it has expanded from its original OpenAI Codex-based foundation to support multiple underlying models over time. The SkillVeris post Vibe Coding: How to Build Faster with AI Without Losing Control discusses how to use AI coding assistants like Copilot effectively.
