-
Type a comment describing the function. Example:
-
Press the AI generate command (
Ctrl + IorCmd + I). -
Cursor AI will create the function for you, with proper syntax and structure.
3. Get Instant Code Explanations
When working with unfamiliar code:
-
Highlight the code block.
-
Right-click and select Explain Code.
-
Cursor AI will provide a plain-language explanation of what the code does.
This is especially helpful for onboarding to a new project or learning a new language.
How to Debug Code Faster with Cursor AI
Debugging is where Cursor AI truly shines. Here’s how to make the most of it:
1. Identify the Problem
-
Run your code inside Cursor AI’s integrated terminal.
-
If an error appears, highlight the problematic section.
2. Ask AI to Suggest a Fix
-
Select the code or error message.
-
Press the AI command shortcut (
Ctrl + Shift + I/Cmd + Shift + I). -
Cursor AI will analyze the problem and offer a fix.
Example:
If you have:
Cursor AI might return:
…and explain that you missed the colon.
3. Optimize Your Code
Debugging isn’t just about fixing errors — it’s also about improving performance.
-
Highlight the function or code block.
-
Ask AI: “Optimize this function for speed”.
-
AI will refactor the code while keeping its functionality.
4. Prevent Future Bugs
Cursor AI can also write unit tests for your functions:
-
Right-click your function → Generate Tests.
-
AI will create test cases based on your code’s logic.
Advanced Features to Boost Productivity
Beyond writing and debugging, Cursor AI offers powerful tools to make development smoother:
-
Multi-File Context Awareness: AI suggestions take into account other files in your project.
-
Live Collaboration: Share your workspace and code with teammates in real time.
