Refactoring Code with Cursor

How to clean up messy code fast using AI suggestions.

Lesson Notes

AI-assisted refactoring is one of the highest-ROI uses of Cursor. Select any block of code, use Cmd+K, and describe the improvement. Good refactoring prompts: "add error handling", "break this into smaller functions", "add TypeScript types", "make this more readable", "remove duplication". The AI keeps the logic the same while improving structure.
