Prompt Armour — AI Privacy Guard & Data Leak Prevention

Stop leaking secrets to AI. Detects and redacts passwords, API keys, and personal data before it reaches ChatGPT, Gemini, or Claude.

PROMPT ARMOUR — Your Last Line of Defense Before Hitting Enter Every day, millions of people accidentally paste passwords, API keys, emails, and sensitive data into AI chatbots. Once sent, you can't unsend it. Prompt Armour sits between you and AI. It scans your input in real-time, highlights sensitive data instantly, and lets you redact it before it ever leaves your browser. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT CATCHES Personal Information: • Emails, phone numbers, SSNs, credit card numbers Developer Secrets: • AWS Access Keys, Secret Keys, ARNs, EC2 instance IDs • Database connection strings (MongoDB, PostgreSQL, MySQL, Redis) • Authorization headers (Bearer & Basic tokens) • Session cookies Network Data: • IPv6 addresses, MAC addresses, internal IPs Unknown Secrets: • High-entropy scanner catches passwords and keys that don't match known patterns but look like secrets Names & Locations: • Basic NLP-powered detection for names and places in your text ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WORKS WHERE YOU WORK • ChatGPT (chat.openai.com) • Google Gemini (gemini.google.com) • Anthropic Claude (claude.ai) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ REDACT YOUR WAY Choose how sensitive data gets replaced: → Smart Tags: [EMAIL-1], [AWS-KEY-2] — keeps context for the AI → Masking: ********** — classic obfuscation → Full Redaction: [REDACTED] — clean and simple ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BUILT DIFFERENT Real-Time Highlighting: Your sensitive data gets underlined as you type. No delays. No lag. Powered by the CSS Custom Highlight API for zero interference with the chatbot's editor. One-Click Redact: See the highlights. Click redact. Done. A floating toast notification confirms exactly what was caught and blocked. Undo & Revert: Made a mistake? Undo everything with one click. Or hover over any individual redaction to selectively restore just that item. Granular Control: Don't want emails caught? Toggle it off. Need AWS keys blocked but phone numbers allowed? You control every detection category individually. Session Whitelist: Getting a false positive? Click "Allow Once" to whitelist it for the current session. No permanent changes needed. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY BY DESIGN This is non-negotiable: • 100% client-side processing — ALL detection runs in YOUR browser • Zero data transmission — nothing is sent to any external server. Ever. • No accounts required — install and it works • No analytics, no tracking, no telemetry • Shadow DOM isolation — our UI never touches the host page We built a privacy tool. It would be embarrassing if it wasn't private. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BEAUTIFUL BY DEFAULT • Premium dark and light mode UI • Adapts to your system theme automatically • Clean, minimal, stays out of your way • Vercel-inspired design language ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IS THIS FOR? → Developers who paste code snippets into AI daily → Freelancers who handle client credentials and data → Students who copy-paste research with personal info → Security-conscious professionals in any field → Anyone who uses AI chatbots and values their privacy ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ COMING SOON • Team dashboard for organizations • Scan history and reports • Custom detection rules • Slack & Teams alerts • Firefox & Edge support • Compliance exports for SOC2 / HIPAA ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ THE BOTTOM LINE Samsung engineers leaked proprietary code through ChatGPT. Amazon warned all employees about AI data sharing. Italy temporarily banned ChatGPT over privacy concerns. You can't control what AI companies do with your data. But you CAN control what data reaches them in the first place. Prompt Armour. Think before you send. Actually, let us think for you. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FEEDBACK & SUPPORT We're actively building and improving Prompt Armour. • Found a bug?
