Protect Your Privacy When Using AI Tools to Review Documents

Backed by Microsoft For Startups
Guided by Grayver Law Group
AES-256 Encryption
Free during early access

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.

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. Privacy researchers have documented cases where personal data shared with AI chatbots was later found in model outputs, highlighting the importance of pre-upload redaction. 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.

What We Redact

Get AI help with your documents without sharing your actual personal information with any third-party AI service

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

Protects you even if the AI company suffers a data breach because your personal data was never uploaded in the first place

Works with any AI service where you upload documents for analysis

Free and anonymous with no sign-up required and AES-256 encryption throughout the entire redaction process

Risks of Sharing Unredacted Documents

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

Personal data shared with AI chatbots could appear in responses to other users in rare but documented circumstances

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
Review and Redact

Confirm which items to redact. Placeholders like [FULL_NAME] and [SSN] keep the document structure intact for AI analysis.

4
Upload Clean Document to AI

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

Hypothetical Case Study by Justee

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: All personal data was replaced with placeholders before the lease was uploaded to AI tools. The AI was able to analyze lease terms, identify concerning clauses, and provide useful feedback without ever seeing the owner's actual personal information.

Protect My Privacy When Using AI Tools

Why it matters: The owner's SSN, address, net worth, and bank details were all replaced before uploading to AI tools. The AI could still review the lease terms and clauses without accessing any personal data.

No credit card required

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.
