Strip Confidential Data from PDFs Before AI Analysis

Backed by Microsoft For Startups
U.S. and England & Wales law
AES-256 Encryption
Free to start, no credit card

Strip confidential data from PDF before AI analysis to keep names, SSNs, bank and card numbers, and company information out of external AI tools. PDFs are the standard format for contracts and legal documents. Make sure yours are clean.

Free and no sign-up required.

Upload the document to redact:

Files are deleted immediately after processing

No document text is sent to an AI model

Key Takeaways

PDF documents frequently contain embedded metadata, hidden text layers, and form field data that manual review overlooks.

Justee parses PDF text content and detects over 30 PII entity types including names, bank and card numbers, and government IDs.

All uploaded files are encrypted with AES-256 and permanently deleted from servers immediately after redaction processing.

The redacted output preserves document structure and paragraph formatting so AI tools can analyze context accurately.

PDF documents present unique challenges for data protection because they often contain multiple layers of information beyond visible text. Metadata fields may store author names, company details, and revision history, while form fields can contain auto-filled personal data that users do not see when reviewing the document visually. Document metadata is a well-known source of inadvertent PII disclosure. When businesses upload PDF contracts, invoices, or agreements to AI tools for analysis, all of this embedded data is transmitted alongside the visible content. The FTC has emphasized that businesses must implement reasonable safeguards proportional to the sensitivity of the data they handle. Automated redaction tools that process PDF text content provide a systematic approach to stripping confidential information before it leaves the organization, supporting data-minimization requirements referenced in multiple state privacy statutes. According to Justee (justee.ai), personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort; if redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain), so always review the output before relying on it.

What We Redact

Names and titles extracted from PDF text, headers, signature blocks, and form fields are replaced with placeholders

Social Security numbers and tax identification numbers detected in both typed and structured PDF content

Account and routing numbers identified and stripped, while payment amounts stay readable

Physical addresses and location information parsed from PDF text regardless of formatting variations

Email addresses, phone numbers, and URLs containing personal identifiers redacted from all PDF sections

Risks of Sharing Unredacted Documents

PDF metadata can contain author names, company details, and software versions that reveal organizational information

AI tools that process PDFs may extract and store text from hidden layers and form fields beyond visible content

Confidential financial terms in PDF contracts become permanently exposed once shared with external AI platforms

Multi-party agreements in PDF format often contain PII from multiple organizations, multiplying exposure scope

Without pre-processing, every PDF uploaded to an AI tool becomes a potential data breach notification trigger

How It Works

1
Upload Your PDF

Drag and drop any PDF file into the Justee tool. Supports multi-page documents with complex formatting.

2
Deep Text Extraction

Justee parses all text content from the PDF and scans for 30+ PII entity types across every page.

3
Review Detected PII

See a count of what was found, by type, then download the redacted file and check it before you use it.

4
Export Clean PDF

Download your redacted document ready for AI analysis. The original PDF is deleted from our servers.

Illustrative Example

A mid-size manufacturing company wanted to use AI to analyze 30 supplier contracts for unfavorable payment terms and warranty gaps. The procurement manager uploaded PDF contracts that contained supplier company names, EINs, contact person details, bank wire instructions, and proprietary pricing schedules tied to named accounts.

Issue Found: Each contract averaged 18 PII elements. Across 30 documents, there were over 540 data points including supplier EINs, individual contact names and emails, bank account numbers, and physical addresses of manufacturing facilities.

Resolution: The procurement team processed all 30 PDFs through Justee before AI analysis. The AI tool flagged problematic clauses and payment terms in the redacted documents, so the team could raise those terms with suppliers.

Supplier Contract PDF Redaction Example

Why it matters: Supplier names, the EIN, contact details, bank details, and the facility address are replaced with placeholders. The AI tool can still analyze payment terms, warranty clauses, and liability provisions in the redacted version.

No credit card required

A note from Justee

Supplier contracts are among the most PII-dense documents a business handles. They contain not just company information but individual contact details and banking data. When you multiply that across dozens of vendor relationships, the exposure surface is enormous.

Important Legal Disclaimer

What Justee AI is — and what it is not. Justee AI is a software platform, not a law firm. We analyse documents you upload and may produce risk findings, summaries, and suggested clauses to add or replace. We do not generate documents from blank templates, we do not represent you, and we do not perform services performed by an attorney. Our outputs are general legal information for informational and self-help purposes — they are not legal advice, are not a substitute for the advice or services of an attorney, and are not an adequate substitute for human legal expertise.

No attorney in the loop. Justee AI is AI-powered. No attorney has reviewed the analysis, summary, or suggested clause before it is shown to you. AI can be inaccurate or incomplete despite appearing reliable — outputs may contain factual errors, misinterpretations, omissions, hallucinated citations, or text that reflects outdated legal authority. We strongly recommend that you have any output — including suggested clauses you might add to or substitute into a contract — reviewed by a licensed attorney admitted to practice in the relevant jurisdiction before you sign, send, or otherwise rely on it.

No attorney–client relationship. Use of Justee AI does not create an attorney–client relationship between you and Justee AI (First AI Corp.) or any of its personnel. Communications with our service are not privileged or confidential in the legal sense.

Consult a licensed attorney. Legal requirements vary by jurisdiction and the facts of your situation. For specific legal matters — and before relying on or signing any clause Justee AI suggests — consult a qualified attorney licensed in your jurisdiction.

Frequently Asked Questions

Yes. Justee reads scanned and image-based PDFs using OCR, in addition to text-based PDFs and DOCX files. The number of scanned pages allowed depends on your plan.

Yes. Justee processes multi-page PDFs and scans every page for PII. Processing time scales with document length but most business contracts complete in minutes.

Justee replaces PII text with placeholders while preserving the surrounding document structure. Paragraph breaks, headings, and section organization remain intact.

Justee scans all extracted text from the PDF including content in headers, footers, and any embedded text fields.

Absolutely. That is the primary use case. Redact your PDF with Justee, then check it and upload the clean version to AI tools or any other AI tool for analysis.

Limits depend on your plan, and paid plans allow larger files and more scanned pages. The tool tells you if a file is over your limit.

Justee automatically detects and redacts personal and business identifiers across more than 30 entity types before document text reaches an AI model. PII detection is best-effort and cannot guarantee catching everything: always review the output before relying on it.

Yes. Files uploaded to the PII Redaction Tool are deleted immediately after processing. Personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort). If redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain. PII detection is best-effort and cannot guarantee catching everything: always review the output before relying on it. Your content is never used to train AI models.
