Cursor is a code editor with AI built in. If you’ve used VS Code, you already know it.
1. Open your project
Install Cursor from cursor.com, then File → Open Folder and pick your project.
2. The two shortcuts you’ll use constantly
- Edit in place: select code, press Ctrl/Cmd + K, describe the change.
- Chat about your code: press Ctrl/Cmd + L to open the AI chat with your file as context.
3. Let it use the whole repo
In chat, reference files with @filename so Cursor pulls them in. Ask things like:
@auth.ts add rate limiting to the login route.
Review the diff it proposes before accepting. Prefer the AI agents that show changes before applying them — see working safely.
