About OfflineRedact — PII Detection & Redaction
OfflineRedact — Automatically Detect and Redact Sensitive Data Before Sharing with AI Chatbots
Stop accidentally leaking personal information to ChatGPT, Claude, Gemini, Copilot, and other AI platforms. OfflineRedact scans your messages and file uploads in real-time, detecting 36+ types of personally identifiable information (PII) — all processed locally on your device. Your data never leaves your browser.
Every day, millions of people paste sensitive information into AI chatbots without realizing the risk. A quick question about a contract might include client names and tax IDs. A request to summarize a document might expose employee records. A simple email draft could reveal phone numbers, addresses, and financial details. OfflineRedact acts as your last line of defense — catching sensitive data before it reaches any AI service.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Type a message in any supported AI chatbot or platform
2. OfflineRedact instantly scans your text for sensitive data — names, IDs, emails, phone numbers, financial data, and more
3. If PII is detected, you get a clear notification with options to mask, ignore, or review each finding
4. Choose to auto-replace sensitive data with safe placeholders like [NAME], [EMAIL], [SSN] — the AI gets the context it needs without your personal information
5. Send with confidence, knowing your private data stays private
The entire process happens in milliseconds, right inside your browser. There is no server involved, no API call, no cloud processing. Zero data leaves your device.

OfflineRedact uses advanced pattern matching with mathematical validators (Luhn algorithm for credit cards, MOD-97 for IBANs, checksum verification for national IDs) to minimize false positives while catching real sensitive data.

SUPPORTED PLATFORMS

OfflineRedact integrates directly into the platforms you use every day:
▸ AI Chatbots
- ChatGPT (chatgpt.com)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
THREE PROTECTION MODES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Choose the level of protection that fits your workflow:
1. WARN ONLY
Get a clear toast notification when PII is detected. You decide whether to send as-is or take action. Perfect for users who want awareness without interruption.
2. AUTO-MASK (Pro)
PII is automatically replaced with safe placeholders before your message is sent. "Send the invoice to John Smith at john@example.com" becomes "Send the invoice to [NAME] at [EMAIL]". Seamless and automatic.
3. BLOCK & CONFIRM
Sending is blocked when PII is detected. You must explicitly choose to mask, edit, or proceed for each finding. Maximum protection for high-security environments.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
