PromptShield — AI Chat Protector

About

PromptShield is a safety net for anyone using AI chat tools. Before your message is sent, it checks for information you may not have intended to share—like PAN- and Aadhaar-style numbers, bank and card details, passwords, API keys, tokens, and other sensitive patterns.

If something looks risky, you’ll see a clear warning and can edit, auto-redact, or send anyway. You stay in control.

WHO IT’S FOR

• Teams using AI at work who need a quick safeguard before sharing confidential text
• Students and frequent AI users who paste information out of habit
• Families—helping parents, teens, and older adults avoid accidental sharing

HOW IT HELPS

• Intercepts send actions (Enter key and common send buttons) and scans messages locally
• Explains detected risks in plain language with helpful guidance
• Optional Composer Preview shows a subtle hint while typing
• Dev Mode reduces noise for intentional API key usage (warnings remain visible)
• Per-site controls: enable or disable protection where you choose

LANGUAGES

• Supports common Hindi and English phrasing, including Roman Hinglish and Devanagari
• Detects structured formats like PAN, Aadhaar, and other sensitive patterns

PRIVACY

• All scanning happens locally in your browser—no chat data is sent to any server
• No analytics or telemetry collected by the extension
• Settings are stored securely using Chrome sync (like other extensions)

COMPATIBILITY

Works across supported AI chat websites. See the extension’s technical details for the full list of domains.

DISCLAIMER

PromptShield does not replace legal, security, or compliance advice. It’s a helper designed to catch common mistakes before you hit “Send.”
