What this tool does
Find and redact common personal data such as email addresses, phone numbers, card numbers, IP addresses, and selected identifiers in local browser text. The report is designed for review, not as an automatic guarantee.
The page applies deterministic browser-side rules to the supplied text and reports only the signals those rules can identify.
Keep the original nearby so you can confirm every change before publishing, sharing, or storing the output.
Example
Input: Contact Maya at maya@example.com or +1 (415) 555-0134. Card: 4111 1111 1111 1111.
Result: Run the included sample to see the exact, reproducible output.

Tips for better output
- Use representative input, not only ideal examples.
- Keep a copy of the source.
- Review names and numbers carefully.
- Test unusual spacing and Unicode.
- Do not treat pattern matching as legal or security advice.
Processing details
All processing is performed by JavaScript in the current browser tab. The tool does not require an API key or server request.
Automated rules have false positives and false negatives. Unusual formats, context-dependent meaning, and malformed text may require manual review.
Frequently asked questions
Does the PII Redaction Tool send my text to a server?
No. The processing in this page runs in your browser. Files and pasted text are not uploaded by the tool.
Can I rely on every result from the PII Redaction Tool?
Treat the result as a practical first pass. Review important findings against the original material and the rules used by your organization.
What happens when the input is empty?
The tool asks for input instead of producing a misleading blank report.
Can it process Unicode and multiline text?
Yes. It accepts multiline Unicode text, although pattern matching and token boundaries can vary across writing systems.
What should I check before using the output?
Check names, numbers, formatting, and any sensitive or high-stakes details against the source before publishing or sharing the result.
