Free to start, no credit card

Redact PII from criminal defense documents for AI to protect defendant identities, witness details, victim information, and law enforcement records. Justee removes criminal case PII from police reports, discovery materials, and court filings so defense attorneys can use AI for case analysis safely.

Key Takeaways

Criminal case files contain defendant, witness, and victim identities with addresses and contact details

Justee detects and redacts 30+ PII entity types including booking numbers and law enforcement identifiers

Documents are encrypted in transit (TLS 1.2+) and at rest (AES-256) and all files are deleted after redaction completes

Redacted documents preserve factual narratives and legal arguments needed for AI-assisted defense preparation

Criminal defense practice involves handling information where privacy failures can have life-altering consequences. Case files contain defendant names, dates of birth, SSNs, booking numbers, and criminal history details. Discovery materials include witness names and addresses, victim identities and contact information, confidential informant details, and law enforcement officer personal information. Police reports document locations, times, vehicle descriptions with license plates, and detailed factual narratives that identify multiple individuals. When defense attorneys use AI to analyze discovery, identify legal issues, or research comparable cases, every person named in these documents, defendant, witness, victim, and officer, has their personal information transmitted to the AI platform. The consequences of exposure extend beyond privacy: witness intimidation concerns, victim safety, defendant presumption of innocence, and law enforcement operational security all depend on keeping this information controlled. Justee provides automated PII redaction that detects personal identifiers for the parties in criminal case files, replacing each with structured placeholders that preserve the factual and legal narrative while replacing the identifiers it detects. 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

Defendant names, DOBs, and SSNs replaced with structured placeholders

Witness names, addresses, phone numbers, and contact details systematically anonymized

Victim identities and location information redacted throughout discovery materials

Law enforcement officer names and department names removed

Addresses and other location details anonymized

Risks of Sharing Unredacted Documents

Witness identities submitted to AI platforms create intimidation and safety risks

Victim addresses and contact details exposed through AI tools endanger physical safety

Defendant criminal history combined with personal details creates lasting digital exposure

Confidential informant identities represent the highest-stakes PII in any legal file

Law enforcement operational details could compromise ongoing investigations if disclosed

Analyze with AI Safely

Download redacted documents and use AI for suppression motion research, case analysis, or sentencing comparison.

Illustrative Example

A criminal defense firm wanted to use AI to analyze discovery materials across 15 drug cases to identify patterns in search warrant execution that could support suppression motions. The discovery packages contained defendant names and booking information, witness statements with names and addresses, confidential informant references, officer names and badge numbers, vehicle descriptions with license plates, and location details for search warrant executions.

Issue Found: The 15 cases contained personal information for 15 defendants, approximately 40 witnesses, 20 law enforcement officers, and references to confidential informants, representing serious safety implications if exposed.

Resolution: All discovery materials were processed through Justee before AI analysis. Defendant, witness, and officer names, addresses, phone numbers, and locations were replaced with structured placeholders, and the team removed badge numbers and VINs by hand. The AI analyzed search warrant execution patterns using procedural details and legal standards without seeing the redacted identities.

Police Report Excerpt: Before vs. After Redaction

Why it matters: Names, the date of birth, SSN, the witness address and phone, and the location are replaced. Badge numbers, incident numbers, and VINs are not on the detected list and stay as written, so remove them yourself before sharing.

No credit card required

A note from Justee

Criminal case files affect the liberty and safety of every person named in them. Defendants, witnesses, victims, and officers all deserve to have their personal information protected from unnecessary exposure to AI platforms.

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

Partly. Justee detects officer names and department names alongside standard PII. Badge numbers and unit codes have no dedicated detector, so check them in the output.

Justee detects physical addresses, phone numbers, and email addresses wherever they appear, including witness addresses in narrative text. Detection is best-effort, so check addresses written in unusual ways.

Justee processes individual documents in PDF and DOCX formats. Large discovery packages should be processed document by document, with each typically completing in minutes.

Justee detects and redacts names and standard identifiers for individuals mentioned in documents. Coded identifiers and descriptive details that could point to an informant are not reliably detected, so review those passages yourself.

Justee preserves the factual structure, timeline, procedural steps, and legal characterizations in the document. Only personal identifiers are replaced, the narrative of events remains intact for AI analysis.

Case and docket numbers in common formats are detected and replaced with structured placeholders. Booking and incident report numbers have no dedicated detector, so check them in the output.

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.
