Privacy Tool for Uploading Your Documents to AI Safely

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

Justee is a privacy tool for uploading documents to AI that removes your personal information before you share files with any AI service. AI tools can help you understand contracts, summarize documents, and get quick legal insights. But uploading a document to an AI tool means sharing everything in it. Your name, address, Social Security number, bank details, and more. AI companies may retain this data, use it for training, or be vulnerable to breaches. Get AI assistance without giving up your privacy.

Free and no sign-up required.

Upload the document to redact:

Files are deleted immediately after processing

No document text is sent to an AI model

Key Takeaways

AI tools may store, analyze, or use your personal data from uploaded documents for model training or other purposes

Justee strips over 30 types of personal information from your documents before you upload them to any AI platform

Documents redacted with placeholders work well for AI analysis because the structure and context are preserved

Free to use with no account needed and your file is AES-256 encrypted and deleted immediately after redaction

The Federal Trade Commission has issued guidance warning consumers about the privacy risks of sharing personal information with AI-powered tools, noting that data submitted to these platforms may be used for model improvement, shared with third parties, or exposed in security incidents. The FTC recommends minimizing the personal data shared with any online service, including AI tools. Justee provides a practical solution by automatically scanning documents for over 30 types of personal information and replacing each instance with a semantic placeholder before the document is uploaded to any AI platform. Files are encrypted in transit (TLS 1.2+) and at rest (AES-256) and deleted immediately, so detected personal data does not reach the AI service. 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

Use AI tools for document analysis while keeping detected personal information away from third-party platforms

Placeholders preserve document context so AI tools can analyze, summarize, and explain your documents effectively

Less exposure in an AI data breach, because the redacted information was never uploaded to their systems

Works as a pre-processing step before uploading to any AI platform

Free, no sign-up required and your file is AES-256 encrypted and deleted after you download it

Risks of Sharing Unredacted Documents

AI companies have varying and often unclear data retention policies for documents and information users upload to them

Personal data submitted to AI tools could be incorporated into training data and potentially surface in future AI outputs

AI platform data breaches could expose every document you have ever uploaded including all personal information within

Terms of service for many AI tools grant broad rights over uploaded content that most users never read or understand

Once personal data is processed by an AI system, there is no reliable way to ensure complete deletion or removal

How It Works

Illustrative Example

A first-time homebuyer wanted to use an AI tool to review her purchase agreement before signing, but the contract contained both parties' names, addresses, SSNs, and the buyer's mortgage pre-approval details. The purchase agreement was a 28-page PDF including buyer and seller personal details, loan contingency clauses with pre-approval amounts, and earnest money deposit instructions with bank account numbers.

Issue Found: Justee detected 31 personal data items across the agreement, including the seller's SSN in the disclosure section, both parties' addresses, the buyer's mortgage amount, and bank routing numbers for the earnest money deposit.

Resolution: The detected personal data for both buyer and seller was replaced with placeholders. The AI tool analyzed the redacted contract and provided a helpful summary of terms, contingencies, and potential concerns without seeing the redacted personal information.

Home Purchase Agreement Before AI Upload

Why it matters: Both parties' names, addresses, the SSN, the title company, bank, and account number were removed before AI upload. The earnest money amount stays, so the AI could still analyze purchase terms and closing conditions.

No credit card required

A note from Justee

AI tools are great for getting a quick overview of a contract, but they should never have access to your Social Security number or bank account details. Think of redaction as the security checkpoint before your document enters the AI world. It takes a couple of minutes and keeps those details out of the AI's hands.

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

AI companies have different data policies. Some may store uploads for training or improvement. The safest approach is to remove personal data before uploading so it is not exposed, whatever their policy.

Yes. Placeholders like [PERSON_1] and [ADDRESS_1] preserve the document structure. AI tools can analyze terms, clauses, and content effectively without your actual personal information.

Justee redaction works as a pre-processing step before any AI service where you upload documents for analysis or review.

At minimum, remove SSNs, bank accounts, home addresses, and phone numbers. Justee detects over 30 types automatically so you do not need to decide what to look for.

Yes. Your file is encrypted in transit (TLS 1.2+) and at rest (AES-256) and permanently deleted after download. Justee does not retain any data from your document.

Yes. You can use the redacted document with Justee's contract review tool or any other service. The placeholders do not interfere with document analysis.

Justee redacts every type it detects. If the AI needs a specific detail, add it to your prompt yourself, sharing only what is needed.

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).
