Protect Client Confidentiality in AI Document Review

Free to start, no credit card

Attorney client privilege AI document review raises a question courts have started to answer: at least one federal court has held AI chats are not privileged, and voluntary disclosure to third parties can risk waiver. Justee strips client-identifying information from legal files before AI submission, keeping client identifiers out of AI tools and supporting your confidentiality obligations while still benefiting from AI-powered analysis.

Attorney-client privilege shields confidential communications between lawyers and their clients from compelled disclosure, but it does not apply automatically to what a lawyer types into an AI chatbot: at least one federal court has held AI chats are not privileged, and voluntary disclosure to third parties can constitute a waiver, while AI platforms may not qualify for any recognized exception. Redacting client names, case specifics, and other identifying details before AI analysis reduces what an AI platform ever receives, which supports an attorney's confidentiality obligations under ABA Model Rule 1.6. Justee automates this redaction, detecting over 30 types of personally identifiable information and replacing them with structured placeholders that preserve document context without exposing protected communications. Redaction is a technical confidentiality safeguard, not a legal one: it does not create or restore privilege, and lawyers should direct privilege questions to their own ethics counsel. 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

Client names and party identifiers replaced with [PERSON_1], [PERSON_2] to keep client identities confidential

Case numbers, docket references, and court identifiers anonymized with [CASE_NUMBER_1] placeholders

Addresses, contact information, and location data stripped from privileged correspondence

Bank and card account numbers in engagement letters redacted, with fee amounts left for analysis

Attorney bar numbers and firm identifiers removed to prevent reverse identification

Risks of Sharing Unredacted Documents

Submitting privileged documents to AI platforms without redaction may constitute voluntary third-party disclosure

Courts could find privilege waived if client-identifying information is shared with AI service providers

AI platforms terms of service may permit data retention or training use, compounding disclosure risk

Metadata in unredacted documents can reveal client identity even if body text seems anonymized

Malpractice insurers increasingly examine AI usage practices when evaluating coverage for privilege claims

4
Export for AI Analysis

Download the anonymized document and safely use it with any AI platform for analysis or drafting.

Illustrative Example

A corporate defense attorney needed AI assistance drafting a motion to dismiss based on privileged strategy memos exchanged with a Fortune 500 client. The memo collection contained detailed litigation strategy, client executive names, internal code names for the matter, and references to specific financial exposure figures.

Issue Found: Direct upload of the strategy memos would have exposed the client identity, litigation strategy, and settlement authority figures to the AI platform, potentially creating a privilege waiver argument for opposing counsel.

Resolution: The attorney used Justee to redact client identifiers and executive names, then removed the settlement figure by hand. The AI could then analyze argument structure and case law references in the memos without seeing the client's identity or other redacted details.

Privileged Strategy Memo: Before vs. After Redaction

Why it matters: Names, companies, the bar number, the case number, and the email are replaced. The settlement figure is not redacted, so remove it by hand, as the attorney in this example did, before the memo goes to an AI tool.

No credit card required

A note from Justee

Redaction does not create or restore privilege, but it limits what leaves your hands. Careless disclosure can put privilege at risk, so strip identifying information before you submit a privileged document to any AI tool.

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

At least one federal court has held that AI chats are not privileged, and the general principle is that voluntary disclosure of privileged information to third parties can waive privilege. Removing client-identifying data before AI submission reduces what is disclosed. Redaction does not create or restore privilege.

Justee detects and replaces client names, case numbers, court references, bar IDs, email addresses, phone numbers, physical addresses, bank account numbers, SSNs, and other identifying data with structured placeholders. Medical record numbers, policy numbers and amounts are not detected; remove them yourself.

No. Justee processes the file only to redact it. Documents are encrypted in transit (TLS 1.2+) and at rest (AES-256) and deleted immediately after redaction, no person at Justee reviews them, and Justee does not keep copies of uploaded files.

Yes. Justee uses typed placeholders like [PERSON_1] and [CASE_NUMBER_1] that preserve document structure. AI tools can analyze legal arguments, clause patterns, and document organization without needing real client identities.

Yes. Work product doctrine protects attorney mental impressions and legal theories. If your work product contains client-identifying data, redacting before AI submission keeps those details out of the AI platform. Redaction does not create or restore privilege or work product protection.

Justee is not endorsed or approved by any state bar association. It is a privacy tool that attorneys can use as part of their reasonable efforts to protect client data when using technology, consistent with guidance from ABA and various state bar ethics opinions.

Justee supports PDF and DOCX files. These cover the vast majority of legal document formats used in practice.

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.
