Pure local regex detection — text never goes to any AI or server. Credit cards use Luhn and IDs use mod-11-2 checksums to cut false positives.

How it works

Drop a PDF or paste text, and this tool uses purely local regex + checksums to surface personal data: emails, US SSNs, credit/bank card numbers (Luhn-validated to skip random digit strings), China ID numbers (mod-11-2 checksum verified), China mobile numbers, IBANs, IP addresses, and more. Hits are listed so you can redact them next. Zero dependencies, zero uploads, free forever — local regex is actually the most reliable here.

  1. 1.Drop a PDF or paste text — scanned locally, never uploaded
  2. 2.Toggle the PII categories to detect
  3. 3.Review highlighted hits and per-category counts
  4. 4.Head back to the redaction / masking tools to cover them

The broadest coverage is our edge: most competitors only catch email/phone/credit card; we add China ID mod-11-2 validation and credit-card Luhn checks to cut false positives. Pure local regex — your text never goes to any AI or server.

Questions & limits

Won't cards and IDs flag tons of random numbers?

No. Credit cards pass a Luhn mod-10 check, and China IDs pass mod-11-2 checksum plus a birth-date sanity check, so random digit strings are filtered out.

Is my pasted text sent to an AI?

No. This is pure local regex detection; the text never leaves your browser.

Can it detect names and addresses?

Regex excels at structured PII (card numbers, ID numbers, emails). Unstructured data like names and addresses is harder for regex, so combine with manual review.
