Protect Client Data When Using AI-Powered Legal Tools

Free to start, no credit card

Protect client data when using AI legal tools by removing PII before your files reach any AI platform. AI legal tools promise faster research, smarter drafting, and better analysis, but they all require your documents as input. Justee helps you get those benefits while keeping client identifiers out of the input.

Free and no sign-up required.

The legal technology market has seen an explosion of AI-powered tools designed for contract analysis, legal research, document review, and litigation support. These tools offer genuine productivity gains, but they all share a common requirement: they need access to your documents to function. When those documents contain client information, attorneys face a fundamental choice between efficiency and confidentiality. PII redaction eases this trade-off by creating a version of each document that retains its legal substance, with detected client data replaced. After reviewing the output, attorneys can submit the redacted version to the AI legal tool they use. This approach works regardless of the AI tool's own privacy policies, providing a consistent layer of data protection across the attorney's entire technology stack. Justee automates this process with detection algorithms specifically designed for legal document entity types, from standard PII categories to legal-specific identifiers like case numbers and bar admission codes. 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 systematically replaced with [PERSON_1], [PERSON_2] across all documents

Sensitive government identifiers including SSNs and tax IDs removed before any external AI processing

Email addresses, phone numbers, and mailing addresses stripped to prevent client contact exposure

Case-identifying information such as docket numbers and filing references anonymized with tokens

Financial identifiers including trust account and routing numbers redacted

Risks of Sharing Unredacted Documents

AI legal tools process documents on external servers outside the attorney's direct security control

Multiple AI tools in a firm's tech stack multiply the number of platforms receiving client data

Employees may not distinguish between AI tools with different privacy policies and data handling practices

Client data aggregated across multiple AI tool submissions creates a broader exposure profile

Vendor data breaches at AI tool providers could expose client information submitted without redaction

How It Works

Use the redacted document with any AI legal tool, contract analyzer, research platform, or drafting assistant.

Illustrative Example

A boutique employment law firm subscribed to three different AI legal tools, one for contract review, one for legal research, and one for document drafting, and was submitting client documents to all three without redaction. The firm's documents included employment agreements with employee SSNs, severance packages with financial terms, workplace investigation reports with witness statements, and EEOC charge responses with detailed factual allegations.

Issue Found: By using three separate AI platforms without redaction, the firm had distributed sensitive employee PII and confidential workplace investigation details across three different vendor ecosystems, tripling the potential exposure surface.

Resolution: The firm adopted Justee as a universal pre-processing step before any AI tool submission. Documents were scrubbed of detected PII first, then submitted to whichever AI platform was appropriate. This created a single, consistent protection layer across the firm's AI tool stack.

Workplace Investigation Report: Before vs. After Redaction

Why it matters: Names, the SSN, email, and address are replaced. The HR ID is not on the detected list and stays as written, so remove it yourself. Job titles and the timeline stay for AI analysis of the investigation.

A note from Justee

Every AI tool in your tech stack is another potential exposure point. The smartest firms are not choosing between AI and privacy. They are building a redaction step into every AI workflow. It takes a few minutes and reduces the 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.

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

Yes. Defense-in-depth is a fundamental security principle. Even AI platforms with strong privacy policies are still external services. Redacting PII before submission keeps detected client data under your control, regardless of the platform's own practices.

Yes. Justee produces standard text output with typed placeholders that any AI tool can process. Whether you use a general LLM or a specialized legal AI platform, the redacted document works the same way.

Make Justee the first step before any AI tool submission. Train staff to process documents through Justee, download the redacted version, and then submit to the AI tool. This creates a consistent protection layer across all AI platforms.

All of them. Contract review tools, research assistants, drafting platforms, deposition summary tools, and any other AI tool that processes your legal documents should receive redacted inputs.

The free tier handles individual documents efficiently. For firms processing multiple documents daily, paid plans raise the monthly redaction limit. Each document typically completes in minutes.

PII detection is best-effort and may not catch every identifier. Review the redacted file before submission and remove anything that was missed. The on-screen summary shows how many items of each type were found.

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.
