Large language models such as AI models, AI assistants, AI tools, and open-source AI have become increasingly capable tools for legal document analysis, research, and drafting assistance. However, the data handling practices of LLM providers vary significantly, and most commercial LLM services process user inputs on remote servers where data may be temporarily stored, logged, or used to improve future model performance. For attorneys, this creates a tension between the utility of LLMs and the obligation to protect client confidentiality. Redacting personally identifiable information before LLM submission eases this tension by keeping detected client data away from the model. Justee automates this process specifically for legal documents, detecting entity types that are common in legal contexts, such as case numbers, bar identification numbers, and court references, in addition to standard PII like names, SSNs, and addresses. The result is a document that an LLM can analyze effectively with detected client information 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

Names of all parties, witnesses, judges, and attorneys replaced with sequential [PERSON_N] placeholders

Court identifiers including case numbers, docket IDs, and filing references anonymized to [CASE_NUMBER_N]

Financial identifiers such as account numbers, routing numbers, and tax IDs redacted

Contact information including email addresses, phone numbers, and physical addresses removed

Professional identifiers such as bar numbers, medical license numbers, and NPI numbers stripped

Risks of Sharing Unredacted Documents

LLM providers may retain input data temporarily or permanently depending on their terms of service

Cloud-based LLMs process data on shared infrastructure, increasing potential exposure surface

Prompts containing client PII may appear in provider logs or debugging systems

Some LLM outputs are reviewed by human evaluators at the provider company for quality assurance

Cross-referencing redacted but patterned data could potentially re-identify clients without full redaction

How It Works

1
Upload Legal Document

Submit your contract, agreement, pleading, or memo in PDF or DOCX format to the Justee tool.

2
Smart Entity Detection

Justee identifies legal-specific PII including party names, case numbers, bar IDs, EINs, and account numbers.

3
Verify Redacted Output

Open the redacted file and check that the sensitive data you care about has been replaced with typed placeholders.

4
Submit to Any LLM

Download the clean document and use it with AI models, AI assistants, AI tools, open-source AI, or any other LLM platform.

Illustrative Example

An intellectual property law firm was building a research workflow using AI assistants to analyze patent licensing agreements for common royalty structures. The licensing agreements contained inventor names, patent numbers linked to specific individuals, licensing fee structures, corporate party names, and confidential royalty percentages.

Issue Found: Submitting unredacted licensing agreements would have exposed proprietary business terms, inventor identities, and confidential royalty rates to the LLM provider's servers.

Resolution: The firm processed all 30 licensing agreements through Justee before LLM submission. Party names, patent-holder names, and contact details were replaced with structured placeholders, while royalty rates stayed in the text because the analysis needed them. The AI assistant identified royalty structure patterns across agreements without seeing the redacted names.

Patent License Agreement: Before vs. After Redaction

Why it matters: Company names, the EIN, the representative, and contact details are replaced. The patent number and royalty rate are not redacted, so remove them yourself if they are confidential. The LLM can still analyze license structure and grant scope.

No credit card required

A note from Justee

The legal profession is adopting LLMs faster than ethics rules can keep up. Until the rules catch up, the safest approach is simple: keep client identifiers out of what you send to an LLM. Redact first, analyze second.

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

Justee produces redacted documents that work with any LLM, including AI models, AI tools, open-source AI, Mistral, and any other language model. The output is platform-agnostic clean text with structured placeholders.

In addition to standard PII like names and SSNs, Justee detects legal-specific identifiers including case/docket numbers, bar admission numbers, and EINs commonly found in legal documents.

Yes. Justee uses typed, sequential placeholders (e.g., [PERSON_1], [ORGANIZATION_2]) that maintain relational context. LLMs can identify which entity is referenced where, analyze clause structures, and provide substantive assistance without real data.

The free tier handles individual documents efficiently. For firms processing large document sets regularly, paid plans raise the monthly redaction limit. Each document typically processes in minutes.

Documents are encrypted in transit (TLS 1.2+) and at rest (AES-256) and permanently deleted immediately after redaction is complete. Justee does not keep copies of uploaded or processed documents.

Absolutely. If your firm runs a local LLM instance, Justee's redacted output can be used with it just as easily as with cloud-based models. Redaction adds a privacy layer regardless of where the LLM runs.

Yes. Along with the document text, Justee strips document metadata such as author and document properties, and removes comments. Checking the output is still good practice.

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.

PII is replaced with semantic placeholders like [PERSON_1], [SSN_1], and [ORGANIZATION_1] that preserve the document relational structure. LLMs can still understand which entity is referenced where without seeing the replaced values.

Your documents stay inside Justee's AWS environment. Detection uses pattern recognizers and an entity-recognition model on Justee's servers; no document text goes to an AI model. Your documents are never sent to AI platforms or third-party APIs outside that environment.

Justee uses pattern recognizers and an entity-recognition model on Justee's servers; no document text goes to an AI model. Recognizers cover legal identifiers such as court case numbers and attorney bar IDs. While this provides broad coverage across 30 entity types, detection is not guaranteed to be 100% accurate. Always review the redacted output before submitting to any LLM.

Your original file is deleted from our servers immediately after redaction completes. The redacted version is deleted immediately after you download it.

Justee detects more than 30 entity types. Personal: names, Social Security numbers, individual tax IDs (ITIN), U.S. street addresses, email addresses, phone numbers, dates of birth, driver's license and U.S. passport numbers, bank account, credit card, IBAN and routing numbers, Medicare IDs, NPI and medical license numbers, IP and MAC addresses, URLs, and cryptocurrency wallet addresses. Corporate and legal: organization names, EINs, business license numbers, SWIFT/BIC codes, court case numbers, and attorney bar IDs. Medical record numbers, policy numbers and amounts are not detected; remove them yourself.

Yes. You get free redactions per month without signing up. Create a free account for more redactions per month. Premium plans provide even larger limits.

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.
