The original AI pair programmer

GitHub Copilot, built with OpenAI, is the most widely adopted AI coding assistant. It offers whole-line and whole-function completions inside virtually every editor, a Chat surface for questions, slash commands for tests and docs, and Copilot Workspaces for agentic planning. The 2024-2025 additions — multi-model support, code review, and the CLI agent — turned it from an autocomplete into a full coding companion. Copilot Free now gives individuals a real monthly quota at no cost.

Who it's for: Every developer, from students to enterprise teams, who wants completions, chat, and reviews without leaving their workflow.

The honest take

✓ What works

Broadest editor support
Free tier for individuals
Backed by GitHub/OpenAI
Constantly improving

✗ What doesn't

Less agentic than Codex/Devin
Quality varies by language
Needs network
Can suggest stale patterns

Verdict

Copilot is still the safest default AI coding assistant — free to start, everywhere you work, and now with chat and review. Power users may want Cursor or Codex on top.
