Redact Client Information Before Using AI at Law Firms

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

Redact client information before using AI at your law firm to protect confidentiality. AI tools are powerful for legal research and drafting, but pasting client data directly into them creates serious risks. Justee removes names, SSNs, and 30+ PII types from your documents so your firm can use AI safely.

Free and no sign-up required.

The rapid adoption of AI tools in legal practice has outpaced the development of comprehensive ethical guidelines for its use. third-party AI providers's terms of service have evolved, but questions remain about data retention, training data usage, and the security of information submitted through the chat interface. Several prominent law firms have issued internal policies restricting or prohibiting the use of AI tools with client data, while others have adopted a middle approach that permits AI use only after client-identifying information has been removed. This redaction-first approach allows attorneys to benefit from AI tools's analytical and drafting capabilities without exposing confidential client details. Justee facilitates this workflow by automatically scanning legal documents for over 30 types of personally identifiable information and replacing each instance with a structured placeholder. The result is a document that retains its legal structure and analytical value, with detected client data replaced by placeholders. 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 and opposing party names replaced with [PERSON_1], [PERSON_2] before AI tools submission

Social Security numbers, dates of birth, and government IDs redacted to prevent identity exposure

Firm details including case numbers, bar IDs, and firm names anonymized for external AI use

Physical and email addresses stripped to prevent client location identification

Financial identifiers such as account and routing numbers removed, with amounts left for analysis

Risks of Sharing Unredacted Documents

AI tools inputs may be stored, logged, or used for model training depending on account settings

Copy-pasting client data into AI tools constitutes sharing with a third-party technology provider

Staff members may inadvertently paste sensitive client details without realizing the disclosure risk

AI tools conversations may be accessible to third-party AI providers employees for quality review purposes

Firm-wide AI tools usage without redaction policies creates systemic confidentiality exposure

How It Works

1

2
PII Auto-Detection

Justee identifies names, SSNs, addresses, account numbers, provider IDs, and 30+ other PII types.

3
Review the Redactions

Check the redacted file: each placeholder label shows what entity type was detected and replaced.

4
Paste Into AI tools Safely

Copy the redacted text or download the clean file, then use it with AI tools or any AI tool with confidence.

Illustrative Example

A personal injury law firm with 12 attorneys wanted to use AI tools to draft demand letters more efficiently based on templates from prior successful cases. The template demand letters contained plaintiff names, medical provider information, injury descriptions tied to specific individuals, insurance policy numbers, and settlement demand figures.

Issue Found: An associate had already pasted three unredacted demand letters into AI tools before the managing partner realized client names, medical details, and insurance information were being shared with third-party AI providers's platform.

Resolution: The firm immediately adopted Justee as a mandatory pre-processing step. Demand letter templates were redacted, replacing plaintiff names, medical providers, and claim numbers with placeholders, while settlement figures stayed unless removed by hand. AI tools could still analyze letter structure and suggest improvements without seeing the redacted client information.

Redact Client Info Before Using AI at Law Firms

Why it matters: Names, the claim number, the date of birth, the address, and the hospital are replaced, and the client keeps one placeholder throughout. The medical bill total stays, so AI tools can review tone and structure with the numbers intact.

No credit card required

A note from Justee

AI tools are a tool, not a confidant. Every time an attorney pastes client data into an AI chatbot without redaction, they are making a choice that could have disciplinary consequences. A redaction step that takes minutes is a simple way to reduce that 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

By default, AI tools may use conversation data for model improvement unless you opt out through settings or use the API with data retention controls. Regardless of settings, redacting PII before submission reduces the risk of client data being stored or processed.

Yes. Justee is browser-based and requires no installation or account for basic use. Any attorney or staff member at your firm can access it immediately. For higher-volume usage, Justee offers plans with additional features.

Absolutely. Justee uses typed placeholders like [PERSON_1] and [ORGANIZATION_1] that maintain document context. AI tools can analyze clause language, suggest improvements, and assist with drafting without needing real names or data.

Even with enterprise AI plans that offer enhanced privacy controls, redacting PII adds an additional layer of protection. Defense-in-depth is a standard security principle, and pre-submission redaction keeps detected client data under your control.

Start by requiring all documents to pass through a PII redaction tool like Justee before any AI submission. Train staff on the workflow, designate a compliance officer to monitor adherence, and document the policy as part of your firm's technology use guidelines.

Yes. Justee produces a clean, redacted document that can be used with any AI service, or any other generative AI tool. The redaction is platform-agnostic.

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.
