What PII does SafeRedact detect?
SafeRedact's AI identifies both structured and unstructured PII across documents:
Pattern-based PII: Social Security numbers, credit card numbers, phone numbers, email addresses, dates of birth, driver's license numbers, passport numbers, financial account numbers, and IP addresses. These follow predictable formats and are detected with high precision.
Context-dependent PII: Personal names, physical addresses, employer names, medical conditions, and other identifiers that require understanding context to recognize. This is where AI dramatically outperforms regex-based tools — a name like "James" is only PII when it appears as an identifier, not when it's part of "James River" or "St. James Hospital."
Composite identifiers: Information that becomes PII when combined — a job title plus a department in a small organization, or an age plus a postcode that narrows identification. AI detection flags these combinations that rule-based systems miss entirely.
Why AI beats pattern matching for PII
Traditional redaction tools use regular expressions: patterns like XXX-XX-XXXX for SSNs or sequences of digits for phone numbers. This catches the obvious structured identifiers but consistently fails on the PII categories that cause the most compliance problems.
Names are the clearest example. "Sarah Johnson" is PII in a personnel file. "Johnson & Johnson" is a company name. "Johnson valve" is a machine part. Pattern matching cannot distinguish between these without understanding context. AI can.
Addresses present the same challenge. "123 Main Street, Apt 4B, Springfield, IL 62701" is clearly an address. But "the Springfield office" in an internal memo might also constitute location PII if it narrows identification. AI evaluates context; regex checks format.
SafeRedact uses Anthropic's Claude to classify each detected item with a category label (name, address, SSN, phone, etc.) and a confidence score. You review the detections, approve or dismiss each one, and apply permanent redaction. The AI handles the detection; you handle the decisions.
How PII redaction works in SafeRedact
1. Upload: Drag a PDF into SafeRedact or use the file picker. For scanned documents, built-in OCR (Tesseract.js) extracts text from images automatically.
2. AI detection: The extracted text is analyzed by Claude AI via Anthropic's zero-retention API. Every PII instance is flagged with a category label and mapped to its position in the document. The original file stays in your browser — only extracted text coordinates are sent for analysis.
3. Review: Each detection appears as a highlighted overlay on the document. Click to approve or dismiss. For DSAR workflows, you can keep one person's data while redacting everyone else's. Draw manual redaction boxes for anything the AI missed.
4. Redact and download: Click Apply. SafeRedact renders each page as a new image with redacted content physically absent — pixel-burn redaction. The sensitive data doesn't exist in the output file. It cannot be recovered by copy-paste, Photoshop, or any other method.
PII redaction for compliance
Different regulations define PII differently and impose different redaction requirements:
GDPR / UK GDPR: "Personal data" is any information relating to an identifiable natural person. Redaction is required when sharing data in DSAR responses, publishing documents, or transferring data where the legal basis doesn't cover all individuals mentioned. GDPR redaction guide →
CCPA / CPRA: "Personal information" includes identifiers, commercial information, biometric data, internet activity, geolocation, employment data, and education information. Required for consumer access request responses where third-party data is present. CCPA DSAR guide →
HIPAA: Protected Health Information (PHI) includes 18 specific identifiers. The Safe Harbor method requires removal of all 18 to achieve de-identification. SafeRedact detects PHI categories including patient names, medical record numbers, dates, and geographic identifiers.
FOIA: Exemption 6 protects personal privacy information in government records. Agencies must redact PII before releasing documents under public records requests. FOIA redaction guide →
Common PII redaction use cases
DSAR responses: Remove third-party PII while preserving the requester's data. The selective redaction workflow in SafeRedact is designed specifically for this. DSAR redaction guide →
Legal discovery: Redact privileged information and non-party PII from documents before production. Court rules require removal of SSNs, financial account numbers, dates of birth, and names of minors from public filings.
Real estate transactions: Redact tenant SSNs, bank account numbers, and financial details from rent rolls and applications before sharing with buyers, lenders, or auditors.
HR and employment: Remove employee PII from performance reviews, payroll data, and personnel files when sharing with managers, auditors, or in response to litigation. Employee document redaction guide →
Financial services: Redact client PII from statements, reports, and correspondence before sharing with regulators, auditors, or third parties.
Insurance claims: Remove claimant and policyholder PII from claims documents, medical records, and settlement files before sharing with adjusters, reinsurers, or legal counsel. Insurance redaction →
Why SafeRedact for PII redaction?
Documents never leave your browser. Other AI redaction tools require you to upload files to their servers. SafeRedact processes documents locally — only extracted text coordinates are sent for AI analysis, and even that uses Anthropic's zero-retention API. For organizations handling sensitive PII, this architecture eliminates an entire category of data processing risk.
True permanent redaction. Pixel-burn rendering means the redacted content is physically absent from the output file. Not hidden behind a box, not obscured by an overlay — gone. The output cannot be reverse-engineered.
No signup required. First document is free. No account creation, no credit card, no software installation. Upload a PDF and start redacting immediately.
Simple, transparent pricing
Free: First document, no signup. Day Pass ($12): Unlimited documents for 24 hours. Monthly ($29): Unlimited documents. Annual ($99): Best value — unlimited documents, all year. Enterprise: Volume licensing, API access, dedicated support — contact us.
Frequently asked questions
What is PII redaction?
PII redaction is the permanent removal of personally identifiable information from documents. Unlike masking (which replaces data with placeholders) or encryption (which makes data unreadable but recoverable), redaction destroys the data so it cannot be restored.
What types of PII can SafeRedact detect?
SafeRedact detects SSNs, names, addresses, phone numbers, email addresses, dates of birth, financial account numbers, medical record numbers, driver's license numbers, passport numbers, and other identifiers. AI-powered detection catches context-dependent PII that pattern-matching tools miss.
Is SafeRedact HIPAA compliant?
SafeRedact is not certified for HIPAA. While the browser-based architecture minimizes data exposure, extracted text is processed via Anthropic's API (with zero data retention). Organizations with strict HIPAA requirements should evaluate whether this meets their policies.
How is SafeRedact different from Adobe Acrobat redaction?
Adobe Acrobat requires manual identification of each PII instance — you draw boxes around text to redact. SafeRedact uses AI to automatically detect PII across entire documents, then lets you review and approve. For a 50-page document, this reduces redaction time from 30+ minutes to under 2 minutes.
