Free Debugging Tool
AI Debugger
Paste your buggy code (and your error) — get the root cause plus a corrected, working version.
How to use the AI Debugger
Become your own faster debugging partner.
1
Paste the failing code
Include the full function or script that fails. Context matters — a lone line can't be debugged reliably.
2
Add the error message (optional)
Paste the stack trace, exception message or symptom. The more specific, the more precise the diagnosis.
3
Get the root cause and the fix
The AI explains what went wrong and why, then returns corrected code. Apply it, re-run your tests, and learn from the explanation so it doesn't happen again.
AI Debugger — FAQ
Will it always fix my code?
It fixes the vast majority of logic, syntax and common runtime errors. Complex, project-specific bugs may need additional context — mention your framework and versions.
Can I paste an entire stack trace?
Yes, up to 800 characters in the error field. For long traces, paste the top 3–5 lines that mention your code files.
How is this different from the Code Explainer?
The Explainer helps you understand code. The Debugger assumes something is broken and returns a corrected version with a diagnosis. Use them together.
Is it safe to paste private code?
Code is processed server-side and not stored. For highly sensitive code, consider removing secrets and credentials before pasting.
