PII Detector

AI / Agent

Detect and redact personally identifiable information: emails, phones, SSNs, credit cards, IPs, IBANs, and crypto wallets

Pasting a log dump or a bug report into an LLM prompt is exactly the moment you want to know if it contains an email, phone number, SSN, credit card, IP, IBAN, or crypto wallet address first, and this scans for all of them using pattern matching that runs entirely client-side, which matters since you're often pasting genuinely sensitive data into it. Redact mode produces a sanitized version ready to share in a support ticket or prompt. It's worth being honest about the limits: this catches well-structured patterns but misses unstructured PII like names or addresses embedded in free text, and it will occasionally flag a numeric false positive that matches a card or IBAN pattern without being real. A clean scan is not a compliance guarantee, and neither is a flagged match automatically real PII.

How to use PII Detector

  • 1.Paste a document or log dump to scan for emails, phone numbers, SSNs, credit cards, IPs, IBANs, and crypto wallet addresses.
  • 2.Use the redact mode to generate a sanitized version of text before sharing it in a bug report, support ticket, or LLM prompt.
  • 3.Run it over sample data before ingesting it into an analytics pipeline to catch PII that shouldn't be logged or stored.

Frequently asked questions

Does this run in my browser or on a server?
Detection runs entirely client-side using pattern matching — your text is never uploaded, which matters since you're often pasting sensitive data into it.
Will it catch every kind of PII?
No — it detects well-structured patterns (emails, phone formats, card numbers, etc.) but can miss unstructured PII like names, addresses in free text, or PII in non-standard formats. Don't treat a clean scan as a compliance guarantee.
Does it produce false positives?
Yes, occasionally — a string that matches a credit card or IBAN pattern numerically isn't necessarily real PII, so review flagged matches rather than trusting them blindly.
Can I use this to scan files in bulk?
The browser tool works on pasted text; for scanning many files programmatically, use the REST API or SDK to run detection in a script.
