What Is Cursor AI? A Plain-Language Introduction
A mental model you can explain to a colleague in 60 seconds.
What You Will Learn
- Explain what Cursor is to a colleague.
- Identify Cursor's key features.
- Describe how Cursor differs from VS Code + Copilot.
- State what Cursor is good and bad at.
- Formulate a 60-second explanation.
Why This Matters
If you cannot explain what a tool is, you cannot use it deliberately.
Concept Explained
Cursor is an AI-first code editor built on VS Code. It integrates AI deeply into the development workflow with Tab (AI autocomplete), Composer (multi-file editing), Agent mode (autonomous coding), Chat (codebase Q&A), and multi-model support (GPT-5, Claude, Gemini).
