Remove PII Before ChatGPT

What this tool does

AI assistants often need context, but they rarely need real customer names, contact details, account numbers, or confidential links. This tool performs a local first-pass scan and replaces recognizable patterns with placeholders.

The cleaned text remains editable. You can restore details that are genuinely necessary, remove extra context, and check whether the prompt still makes sense before copying it.

Recommended workflow

1. Paste only the relevant sectionAvoid copying an entire email chain or document when a smaller excerpt is enough.
2. Run the local scanReview which pattern types were found and inspect every replacement in context.
3. Check indirect identifiersLook for unique job titles, project names, uncommon dates, locations, and private business facts the pattern scan cannot understand.
4. Copy the reviewed versionShare only after the placeholders are consistent and the useful problem remains clear.

Read the testing methodology and known limitations.

Known limitations

Automated processing can miss unusual formats, indirect identifiers, hidden data, unsupported structures, and information that requires human judgment. This tool may miss:

• single-word names
• postal addresses without a clear pattern
• industry-specific identifiers
• private facts revealed by context
• text inside images or unsupported documents

Do not describe the result as fully anonymous, legally compliant, secure, or impossible to re-identify. Review the exact final artifact before sharing it.
