Prompt Shield

Prompt Shield helps you protect sensitive information when using AI assistants.

WHAT IT DOES:
Automatically detects and redacts emails, phone numbers, credit cards, API keys, social security numbers, and custom terms before you send prompts to ChatGPT, Claude, and other AI services.

WHY YOU NEED IT:
Every day, people accidentally leak confidential client data, API keys, and personal information to AI chatbots. Prompt Shield gives you a safety net — review and redact sensitive data with one click before it's sent.

HOW IT WORKS:
1. Type your prompt (with or without sensitive data)
2. Click "Redact & Label" button
3. Review the redaction preview (see exactly what changed and why)
4. Apply to editor or copy to clipboard

FEATURES:
• Automatic detection of sensitive data types
• Transparent diff view showing what was redacted and why
• Customizable disclosure labels
• Audit log of all redactions with timestamps
• Custom term support (add your own terms to redact)
• 100% local processing — no data sent to external servers

PRIVACY & SECURITY:
All processing happens entirely in your browser. Zero data is collected, stored remotely, or sent to any external service.

PERFECT FOR:
Consultants, lawyers, financial advisors, developers, healthcare professionals, and anyone handling confidential information.
