Before & After

Before

This Employment Agreement is entered into by John A. Smith, residing at 2847 Riverside Drive, New York, NY 10025, and Acme Technologies Inc. (EIN 83-2941057). Contact: john.smith@gmail.com, (212) 555-0147.

After

This Employment Agreement is entered into by [PERSON_1], residing at [ADDRESS_1], and [ORGANIZATION_1] (EIN [TAX_ID_1]). Contact: [EMAIL_1], [PHONE_1].

PII detection is not guaranteed to be 100% accurate. Some entity types may not be detected in all document formats or languages. You must review the redacted output before sharing. See our Terms of Use for full disclaimers.

Why Mask PII in Documents?

Personally identifiable information left inside contracts, agreements, and legal filings creates real risk every time a document is shared, stored, or forwarded. PII masking replaces sensitive values with safe placeholders, so you can collaborate, file, or publish without exposing anyone’s private data.

Before Uploading to AI Tools

Third-party AI assistants are increasingly used to summarize, translate, and analyze contracts. Masking PII before uploading keeps the names, SSNs, financial accounts, and addresses it detects out of the AI tool; review the output for anything it missed.

Prevent AI Model Training on Your Data

Many AI providers reserve the right to use uploaded content for model improvement. Even when they don’t, data leaks and policy changes happen. Masking PII before any AI interaction keeps the identifiers it detects out of the AI tool; review the output for anything it missed.

Regulatory Compliance

Laws like CCPA, GDPR, and HIPAA require organizations to minimize exposure of personal data. Redacting PII before sharing documents helps satisfy data-minimization obligations and reduces the scope of potential compliance violations.

Data Breach Prevention

Every document that contains names, SSNs, or financial account numbers is a potential breach target. Removing PII at the source reduces that risk before a document leaves your control; review the output for anything it missed.

Safe Collaboration & Outsourcing

When sending contracts to outside counsel, auditors, or third-party reviewers, redacted documents let recipients focus on the substance, including terms, clauses, and obligations, without accessing anyone’s personal information.

Litigation & Court Filings

Courts often require masking or redaction of Social Security numbers, financial accounts, and other sensitive identifiers before documents are filed on the public record. PII masking automates what would otherwise be tedious manual redaction.

Training & Templates

Real contracts make the best training material, but only when private data has been removed. Redacted documents can serve as templates and examples with less personal data in them.

Internal Audits & Reporting

Teams that review contract portfolios, analyze clause patterns, or generate compliance reports can work with redacted copies, gaining full visibility into document content while keeping personally identifiable information out of internal dashboards and reports.

PII Redaction FAQ

What happens to my uploaded file?

Your original file is deleted from our servers immediately after redaction completes. The redacted version is deleted immediately after you download it. If you never return to download it, a safety-net cleanup removes it within 30 minutes. We never retain your documents beyond this short window.

Is my data stored anywhere?

No. Your original file is deleted immediately after redaction. The redacted output is deleted immediately after you download it (or within 30 minutes as a safety-net if you never return to download). No document content is permanently retained. The PII mapping used during redaction is never persisted.

What types of PII are detected?

We detect these identifiers:

Personal PII

Names
Social Security numbers (SSN) and individual tax IDs (ITIN)
U.S. street addresses and PO boxes
Email addresses and phone numbers
Dates of birth
Driver's license and U.S. passport numbers
Bank account, credit card, IBAN and routing (ABA) numbers
Medicare Beneficiary IDs, National Provider Identifiers (NPI) and medical license numbers
IP and MAC addresses, URLs and cryptocurrency wallet addresses
Nationality, religious or political affiliations

Corporate & Legal PII

Organization names
Employer Identification Numbers (EIN)
Business license numbers
SWIFT/BIC bank codes
Court case numbers
Attorney bar IDs

Medical record numbers, policy numbers and amounts are not detected; remove them yourself.

Does this work with scanned PDFs?

Yes. The PII Redaction Tool reads scanned and image-based PDFs using OCR, in addition to text-based documents. The number of scanned pages allowed depends on your plan.

Is this service free?

Yes, within a limit. You get a limited number of free redactions without signing up. To increase your limit for free, sign up for a free account. Paid plans provide larger limits. See Pricing for details.

How are placeholders formatted?

PII is replaced with semantic codes like [PERSON_1], [SSN_1], [EMAIL_1], [ADDRESS_1]. Each unique value gets a numbered code, so repeated references to the same person or address use the same placeholder throughout the document.

Can I undo the redaction?

No. The redacted document replaces PII permanently. Make sure to keep your original file before uploading.

What file formats are supported?

PDF (.pdf) and Word (.docx). The redacted file is returned in the same format you upload.

What languages are supported?

The PII Redaction Tool is optimized for English documents. Non-English PII may not be fully detected.

How accurate is the PII detection?

The PII Redaction Tool uses pattern recognizers and an entity-recognition model on Justee's servers; no document text goes to an AI model. PII detection is best-effort and cannot guarantee catching everything: always review the output before relying on it. Some entity types may go undetected in non-English text, unusual formats, or highly domain-specific content. False positives (non-PII flagged as PII) and false negatives (actual PII missed) can occur. You must review the redacted output before distributing it. The PII Redaction Tool is a supplementary tool. It does not replace manual review by a qualified professional.

How does the detection technology work?

Justee's PII Redaction Tool uses pattern recognizers for structured data like SSNs, EINs, case numbers, and bank routing numbers, and an entity-recognition model for names and organizations. Detection runs inside Justee's AWS environment, and no document text goes to an AI model. Your uploaded file is deleted immediately after redaction, and nothing you upload is used to train AI models.

What is PII masking and how is it different from redaction?

PII masking replaces sensitive data with realistic-looking placeholders (like [PERSON_1], [SSN_1]) so the document remains structurally readable. Traditional redaction typically blacks out or removes text entirely. Justee's PII Redaction Tool uses smart masking: each identifier it detects is replaced with a typed, numbered placeholder, preserving document flow. This makes redacted documents suited to AI analysis, legal review, and team collaboration. Review the output for anything it missed.
