This free AI Ruby code fixer takes broken or non-working source code and returns the complete corrected version, with optional error context to guide the fix.

  1. Step 1

    Add your Ruby code

    Type, paste, or upload the broken Ruby code you want to fix.

  2. Step 2

    Add error context

    Optionally include the error message, traceback, or instructions the fix should follow.

    Fix and review

    Click Fix Code, then review the corrected code as a diff or in the plain Fixed Code view.

Choosing the right tool

How is this different from the Ruby Code Checker?

The Ruby Code Checker is diagnostic-first: it gives you a list of issues to work through, with corrected code as a secondary section. The Code Fixer is solution-first: it leads with the complete working code, shown as a diff against your original, and briefly explains what changed. Use the Ruby Code Checker when you want a fuller issue-by-issue review.
