How to remove personal information from text
Removing PII from text is essential before sharing documents or building AI pipelines. Common personal information includes names, emails, phone numbers, addresses, SSNs, dates of birth, credit card numbers, and IP addresses.
Free online tool
Paste text into PrivacyFilter for instant PII removal. Uses OpenAI Privacy Filter for context-aware detection. 3 free redactions per day, no account needed.
REST API
Use POST /api/redact with your license key for batch processing. Returns redacted text plus a JSON entity map with character offsets.
Anonymization vs pseudonymization
Under GDPR, replacing PII with [PERSON_1] while keeping a mapping is pseudonymization. Anonymization means permanently destroying re-identification ability.
