Protect Your Privacy When Using AI Tools to Review Documents

Justee helps you protect my privacy when using AI tools by stripping personal data from documents before you upload them to any AI service. AI tools are incredibly useful for reviewing documents, summarizing agreements, and getting quick answers about your contracts and forms. But every time you upload a document to an AI chatbot, you are sharing everything in it. Your name, address, Social Security number, bank details, and more. AI providers may store this data, use it for training, or suffer data breaches.

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

Add a document to continue

Key Takeaways

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

Justee removes over 30 types of personal data from documents before you upload them to any AI chatbot or service

Redacted documents with placeholders still work well for AI review because the document structure stays intact

Free to use with no sign-up and your files are AES-256 encrypted and deleted immediately after processing is complete

The Federal Trade Commission has raised concerns about the privacy implications of consumer data being used by artificial intelligence systems, noting that personal information shared with AI tools may be retained, analyzed, or incorporated into training datasets. The FTC recommends that consumers exercise caution when sharing sensitive documents with AI-powered services and consider removing personally identifiable information before uploading files. Researchers have shown that AI models can sometimes reproduce parts of their training data, one more reason to redact before upload. Justee provides a free tool that automatically scans documents for over 30 types of personal data and replaces each instance with a semantic placeholder before the user interacts with any AI service. Files are encrypted with AES-256 and deleted immediately after processing. 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

Get AI help with your documents while keeping detected personal information away from third-party AI services

Placeholders preserve document structure so AI tools can still analyze, summarize, and review your content effectively

Limits the damage if the AI company suffers a data breach, because the redacted personal data was never uploaded

Works with any AI service where you upload documents for analysis

Free, with no sign-up required and encryption in transit (TLS 1.2+) and at rest (AES-256)

Risks of Sharing Unredacted Documents

AI companies may store your uploaded documents and personal information indefinitely on their servers without clear deletion

Personal data used to train AI models could, in rare cases, be reproduced in responses to other users

AI company data breaches could expose every document and personal detail you have ever uploaded to their service

Terms of service for many AI tools allow the company to use your uploaded content for model training purposes

You have limited ability to delete your data from AI systems once it has been processed and potentially incorporated

How It Works

1
Upload to Justee First

Before uploading to any AI tool, drop your document into Justee. No sign-up required.

2
Personal Data Detected

Justee finds over 30 types of personal information, names, SSNs, bank details, addresses, across your entire document.

3
Check the Redacted File

Placeholders like [PERSON_1] and [SSN_1] keep the document structure intact for AI analysis. Check the file before uploading.

4
Upload Clean Document to AI

Download the redacted version and upload it to any AI tool. Get the analysis you need without sharing the redacted personal data.

Illustrative Example

A small business owner wanted to use AI tools to review a commercial lease but was concerned about sharing his SSN, personal guaranty details, and bank information with the AI platform. The commercial lease was 22 pages and included a personal guaranty section with the owner's SSN, home address, net worth statement, and bank account details for rent deposits.

Issue Found: Justee detected 21 personal data items including the owner's SSN in the personal guaranty, his home address repeated four times, and bank details in both the guaranty and the payment section.

Resolution: The detected personal data was replaced with placeholders before the lease was uploaded to AI tools. The AI analyzed lease terms, flagged concerning clauses, and gave useful feedback without seeing the redacted personal information.

Protect My Privacy When Using AI Tools

Why it matters: The owner's name, SSN, address, and bank details were replaced before uploading to AI tools. The net worth figure stays, so remove it yourself if needed. The AI could still review the lease terms and clauses.

No credit card required

A note from Justee

AI tools are powerful for document review, but they are not your attorney and they are not bound by confidentiality rules. You have no guarantee about how your personal data will be handled after you upload it. The safest approach is to remove personal details before you interact with any AI service.

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.
