Generative AI encompasses a broad category of tools, from large language models like AI models and AI assistants to specialized legal AI platforms, that create new text, summaries, or analyses based on user inputs. When attorneys provide legal documents as inputs, the generative AI processes every word, including embedded personally identifiable information. This processing occurs on servers controlled by AI providers, raising fundamental questions about data security and client confidentiality. PII scrubbing addresses these concerns by removing identifying information before the document reaches any external system. The scrubbed document retains its legal substance, clause language, argument structure, and procedural references, with detected names, addresses, and other identifying data replaced. Justee performs this scrubbing automatically, using detection algorithms calibrated for the entity types most prevalent in legal documents. The result is a workflow where attorneys can harness generative AI capabilities while keeping detected client information out of what they send. 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

Party names, witness identities, and judge names replaced with [PERSON_N] throughout the document

Government identifiers including SSNs, passport numbers, and driver license numbers scrubbed

Medical identifiers such as provider names, NPI numbers, and Medicare IDs anonymized

Financial identifiers including account and routing numbers replaced with tokens

Organizational identifiers such as EINs, company names, and business license numbers removed

Risks of Sharing Unredacted Documents

Generative AI providers may use submitted text for model fine-tuning or evaluation purposes

PII embedded in legal documents can be extracted and correlated by sophisticated data analysis

A single unscrubbed document may contain PII for dozens of individuals across multiple matters

Generative AI outputs may inadvertently reproduce input PII in generated text or summaries

Firm liability for data exposure increases with each unscrubbed document submitted to AI tools

Use with Any GenAI Tool

Submit the scrubbed document to AI tools, or any generative AI platform with confidence.

Illustrative Example

A healthcare law firm was exploring generative AI to help draft HIPAA-related compliance policies based on templates from their existing client engagements. The template policies referenced specific hospital names, administrator contacts, patient volume statistics, facility addresses, and compliance officer personal details including email addresses and direct phone lines.

Issue Found: The compliance policy templates were effectively maps of each healthcare client's organizational structure, with enough detail to identify facilities and key personnel if shared with a generative AI platform.

Resolution: The firm used Justee to scrub all 20 policy templates before AI submission. Hospital names, personnel details, facility addresses, and organizational specifics were replaced with placeholders. The generative AI then analyzed policy language patterns and helped draft improved templates without seeing the redacted client organizational data.

Healthcare Compliance Policy: Before vs. After Scrubbing

Why it matters: The organization name, compliance officer identity, contact information, facility address, and EIN are scrubbed. Non-identifying operational data like patient volume is preserved since it does not constitute PII, allowing the AI to analyze policy scope and coverage requirements.

A note from Justee

Generative AI is not just another software tool. It is a fundamentally new way of processing information. Attorneys who treat it with the same casual approach as a word processor are taking risks they may not fully understand. Scrub first, generate second.

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.

Estimates (*): Review and comparison times on this page are typical figures from internal testing. Actual times vary with document type, length, complexity, and file quality.

Frequently Asked Questions

In practice, the terms are used interchangeably. Both refer to the process of detecting and removing personally identifiable information from documents. Justee performs this by replacing PII with typed placeholders like [PERSON_1] or [SSN_1].

Yes. Justee produces clean text with structured placeholders that can be used with any generative AI tool, AI tools, open-source AI, AI assistants, or specialized legal AI platforms. The output is platform-agnostic.

Justee detects provider and patient names, facility names, provider IDs (NPI), Medicare IDs, and medical license numbers. These are replaced with appropriate placeholders while preserving the medical-legal context needed for AI analysis.

Absolutely. Even legal AI platforms that claim enhanced privacy should receive scrubbed documents as a defense-in-depth measure. Justee helps keep PII away from external systems regardless of the platform's own privacy claims.

No. Justee performs permanent scrubbing. The original PII is replaced, not masked. The downloaded document contains only placeholders. Justee does not store the original data or maintain any mapping between placeholders and real information.

Justee handles standard legal documents efficiently within the free tier. Size limits depend on your plan. Most legal documents process in minutes, and 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. Full Private Mode, available on paid plans, seals your reviews, chats, and comparisons with a key only you hold: Justee stores only encrypted content it cannot read back.
