How many products does Microsoft have named 'Copilot'?

Commenters say Microsoft uses 'Copilot' as a broad label for AI-powered features across many products.

GitHub Copilot is a paid GitHub service that provides AI code assistance with a limited free tier.

GitHub's MCP server enables AI tools like Claude Code to act on a GitHub account but does not by itself consume Copilot tokens.

Microsoft has a long history of overlapping and confusing product names, which contributes to user confusion.
