Detect and mask personally identifiable information (PII) in text. Great for cleaning data before sharing or publishing, ensuring compliance with data protection regulations like GDPR.
Open PII Masker → free, no sign-inBefore sharing data externally — whether it's a customer dataset, a support transcript, a research sample, or a document going to a third party — you need to make sure personal information has been removed. The PII Masker scans text automatically and masks names, email addresses, phone numbers, and other identifiers, replacing them with neutral markers.
GDPR compliance, data anonymisation for research, redacting customer information before it leaves your organisation, cleaning up datasets before analysis — all of these require PII removal, and doing it by hand is slow and unreliable.
