Code Debugging Agent

Paste an error or a bug and get the cause and the smallest fix that works.

Paste the error message, the stack trace and the code around it. It explains what went wrong in plain words, points to where, and suggests the smallest fix with a short reason why. It works with common languages, says when it needs more context, and never needs your keys or passwords.
