GitHub’s AI pair-programmer family—inline completions, chat, code review, and agentic workspaces across IDEs and GitHub itself.
GitHub Copilot started as an inline code-completion tool and now spans chat (Copilot Chat), code review (Copilot Code Review), agentic refactors (Copilot Workspace), and enterprise SKUs (Copilot Business, Copilot Enterprise).
Why teams adopt it
Broad IDE coverage and enterprise governance features (audit logs, policy controls) make Copilot a common default—even where teams also run Claude Code or Cursor for heavier agentic work.
