Shield: AI Privacy for ChatGPT & Claude Firefox

Shield: AI Privacy for ChatGPT & Claude

Stop sharing sensitive data with AI tools. Auto-masks API keys, passwords & personal info in ChatGPT, Claude & Gemini. Free.

Features & Capabilities

🛡️ InfiniUm Shield — AI Privacy Firewall

Every message you send to ChatGPT, Claude, or Gemini passes through their servers. Shield intercepts your prompts before they leave your browser, replaces sensitive data with safe tokens, and swaps them back in the AI's response.

Works automatically. Zero configuration. No account required.

What Shield protects:

🔴 Critical — API keys, passwords, database connections, JWT tokens, private keys, secret environment variables

🟡 Warning — Email addresses, phone numbers, credit cards, private IP addresses, SSNs

🟢 Info — Internal hostnames, system paths, URLs with credentials, personal names

How it works:

  1. You type a message in ChatGPT, Claude, or Gemini
  2. You press Send — Shield intercepts in milliseconds
  3. Sensitive values replaced: [EMAIL_1] [API_KEY_1] [PASSWORD_1]
  4. Clean prompt sent to AI — your data never exposed
  5. AI responds — tokens swapped back to real values automatically

Free tier — 100% local, forever:

  • All processing happens inside your browser
  • Zero data sent anywhere — ever
  • No account, no registration, no telemetry

Pro tier — $8/mo via infinium.tools:

  • Custom rules — protect project names, client names, internal codenames
  • Sync rules across all browsers and devices
  • Advanced detection — .env files, cloud credentials, Stripe keys
  • Full audit log (metadata only, never content)

GDPR & Compliance — Personal data is masked before transmission, helping organisations meet data minimisation obligations under GDPR, HIPAA, and SOC 2.

A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Shield: AI Privacy for ChatGPT & Claude requires a lot of sensitive permissions. Exercise caution before installing.
