GitHub Copilot is the AI coding assistant that started the revolution. Launched in 2021 by GitHub and OpenAI, it was the first widely available AI pair programmer — and in 2026 it remains the most widely used, with over 1.8 million paid subscribers. If you haven''t tried AI code assistance yet, Copilot is the natural starting point.
What is GitHub Copilot?
GitHub Copilot is an AI-powered coding assistant built into your editor that suggests code completions, entire functions, tests, and documentation as you type. It''s powered by OpenAI''s Codex model and trained on billions of lines of public code from GitHub.
It integrates natively with VS Code, Visual Studio, JetBrains IDEs, Neovim, and Azure Data Studio — covering virtually every developer workflow.
Key Features
Inline Code Completions
As you type, Copilot suggests completions ranging from single lines to entire functions. Suggestions appear inline as ghost text and can be accepted with Tab. The more context you provide through comments and surrounding code, the better the suggestions.
Copilot Chat
A conversational AI interface lets you ask questions about your code, request refactors, explain errors, and generate code from natural language descriptions. Copilot Chat understands the context of your current file and workspace.
Copilot in CLI
The GitHub CLI integration brings Copilot into your terminal — explain shell commands, get suggested commands for complex operations, and troubleshoot scripts without leaving the command line.
Pull Request Summaries
GitHub Copilot automatically generates PR descriptions based on the diff, saving developers time on documentation and making code reviews easier.
Copilot Workspace
An agentic feature that takes a GitHub issue and plans, writes, and tests a solution end-to-end — one of the first true autonomous coding agents integrated into a mainstream development platform.

Who Should Use GitHub Copilot?
GitHub Copilot is the go-to choice for developers already deep in the GitHub ecosystem, teams wanting AI assistance with minimal setup, developers working across multiple languages who want consistent support, and anyone who wants the most battle-tested AI coding tool available. If you live in VS Code or JetBrains, Copilot slots in seamlessly.
Final Verdict
GitHub Copilot set the standard for AI pair programming and continues to be refined with each release. At $10/month for individuals it''s one of the best productivity investments a developer can make. The ROI in time saved on boilerplate code, tests, and documentation alone justifies the subscription many times over.
