Code Debugger — Free AI Tool for Students

Debug your code with AI. Free code debugger — paste broken code and error message and get a step-by-step fix with a plain-language explanation instantly.

Frequently asked questions

What languages are supported?

Python, JavaScript, TypeScript, Java, C, C++, Go, Rust, Ruby, PHP, and SQL.

Does it explain the root cause?

Yes. Every fix includes a clear explanation of why the bug occurred, not just how to fix it.

Can I paste just the error message?

Yes, but including both the code and the error message gives significantly better results.

Can it fix multiple bugs in one paste?

Yes. All identified issues in the code are addressed in order of severity.

Does it suggest better code practices?

Yes. After fixing the bug, it may suggest related improvements for code quality.

Can it debug React or framework-specific errors?

Yes. Framework-specific errors (React, Django, Spring, etc.) are handled with context-aware suggestions.

Is the fix always correct?

Highly accurate for common bugs. Always test the fix in your environment before relying on it.

Can it help with runtime vs. syntax errors?

Yes. Both syntax errors (caught before running) and runtime errors (during execution) are diagnosed.
