On-Device PII Scrubber

Mask emails, phone numbers, SSNs, card numbers, and more before pasting text into an AI chatbot or API. Placeholders keep the text usable, and a mapping table lets you restore the originals afterward.

Original text

What should be masked?

Email addresses Phone numbers (US formats) SSNs (dotted and bare 9-digit) Credit card numbers (Luhn-checked) IP addresses (IPv4) URLs Street addresses (basic US pattern) Person namesOff by default: regex name detection is unreliable and will both miss names and flag ordinary capitalized phrases.

Honest limits: this tool uses pattern matching, so it catches well-formed emails, US phone formats, SSNs, Luhn-valid card numbers, IPv4 addresses, URLs, and simple "123 Main Street" style addresses. It will not catch misspelled or unusual formats, international variants, account numbers, dates of birth, or names written in lowercase. Always eyeball the output before sharing.
