GitHub Copilot vs Cursor: Which AI Coding Tool When?

GitHub Copilot lives in your editor and predicts the next few lines based on what you just wrote. Cursor is a whole code editor built around AI — it can refactor across files, run agents, and chat with your full project. They're not the same tool.

Some examples

• You're typing a for-loop in VS Code → Copilot autocomplete is faster.
• You want to rename a function across 12 files and update its callers → Cursor's edit mode wins.
• You're writing a one-off script → Copilot Chat in the sidebar handles it.
• You want an agent to add a whole feature with a multi-step plan → Cursor's agent mode.

Try it!

Try the same small task in both: add a new field to a function and update the 2 places that call it. See which felt smoother.
