Remove Sensitive Data from Documents Before AI Use

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

Remove sensitive data from documents before AI use to keep names, SSNs, bank and card numbers, and addresses out of third-party models. Justee's automated redaction makes every AI interaction safer.

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

Add a document to continue

Key Takeaways

AI services may retain, log, or use submitted data for training unless you proactively strip sensitive content first.

Automated redaction helps catch PII that manual review can miss, including embedded metadata and hidden text fields.

Justee processes documents with AES-256 encryption and deletes uploaded files immediately after redaction is complete.

One-click redaction requires no technical expertise, making it accessible to every team member in your organization.

The growing adoption of generative AI in business workflows has created new vectors for inadvertent data exposure. According to the National Institute of Standards and Technology, organizations should implement data minimization practices that limit the personal information shared with external systems. When employees submit contracts, invoices, or HR documents to AI assistants, they may unknowingly transmit Social Security numbers, bank account details, and client contact information to third-party servers. The FTC has taken enforcement action against companies that failed to implement reasonable data security measures, including cases where employee negligence led to exposure of consumer PII. Automated redaction tools provide a systematic safeguard by stripping identifiable information from documents before they leave the organization, helping businesses align with data-minimization principles embedded in modern privacy frameworks. 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

Personal names and aliases detected across document headers, signatures, and body text

Government-issued identifiers like SSNs, passport numbers, and driver license numbers removed

Email addresses, phone numbers, and URLs stripped from all document sections

Bank account numbers, credit card details, and routing numbers identified and replaced

Dates of birth and Medicare IDs caught and redacted (policy numbers are not detected; remove them yourself)

Risks of Sharing Unredacted Documents

AI providers may log and store all submitted text, creating a persistent record of your sensitive data

Client PII shared through AI tools may violate confidentiality clauses in your business contracts

Employee personal data in HR documents sent to AI could trigger labor law privacy violations

Financial data exposure through AI platforms may create liability under state consumer protection statutes

Accidental disclosure of trade secrets alongside PII compounds both privacy and competitive risks

Export Clean Document

Download the redacted file. Your original is deleted from our servers immediately.

Illustrative Example

A boutique accounting firm with 8 employees began using AI tools to draft client correspondence and summarize tax filings. A junior accountant pasted a client's Schedule C into an AI chatbot to generate a summary letter, including the client's full name, SSN, business address, and gross revenue figures.

Issue Found: The pasted text contained 17 PII elements: the client's SSN, EIN, home address, business address, phone number, email, spouse's name, bank name, and multiple financial figures tied to identifiable information.

Resolution: The firm adopted Justee as a pre-processing step for all AI interactions. Documents are now redacted and checked before any AI submission.

Tax Document Data Removal Example

Why it matters: The client's name, SSN, business name, address, email, and phone number are replaced with placeholders. The revenue figure stays, so an AI tool can work with the numbers without seeing who they belong to.

No credit card required

A note from Justee

The convenience of AI tools should never come at the cost of client confidentiality. For professional services firms, a single data exposure event can destroy years of trust. Pre-redaction creates a reliable boundary between useful AI analysis and unacceptable privacy risk.

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

Any AI tool that processes your text on external servers, including any major AI service, may retain or log the data you provide. Redacting PII before submission protects you regardless of which tool you use.

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.

Currently, Justee processes one document at a time through the web interface. Paid plans raise your monthly redaction limit.

Justee scans all text content within your document, including tables, form fields, headers, and footers. PII found in any section is detected and replaced with appropriate placeholders.

Yes. Redacted documents maintain their structure, grammar, and context. AI tools can analyze, summarize, and extract insights from the redacted text.

Yes. Size limits depend on your plan, and the tool tells you if a file is over your limit. Paid plans allow larger files.

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.
