Description
Detects secrets, credentials and personal data before you send them to ChatGPT, Claude or Gemini — redact instead of expose. ShadowGuard catches secrets and personal data before they reach ChatGPT, Claude, or Gemini — automatically, the instant you hit send. It's easy to paste more into an AI chat than you meant to: an API key still sitting in a code snippet, a customer's email, a card number from a support ticket. ShadowGuard watches your prompt right before it's sent and steps in only when something sensitive is actually there. HOW IT WORKS 1. Type normally in ChatGPT, Claude, or Gemini — no change to your workflow. 2. The moment you hit Enter or Send, your draft is scanned locally against dozens of detectors. 3. Low-risk data is redacted automatically (swapped for a placeholder like [EMAIL_1]) so you can review and send it yourself. High-risk secrets and government IDs are blocked outright, with a clear explanation of what was found. WHAT IT CATCHES Blocked outright: • API keys and other developer credentials • Social Security Numbers Redacted automatically: • Email addresses • Phone numbers • Credit card numbers (with real validation, not just pattern guessing) • IBAN, bank account & routing numbers • Passport numbers • Dates of birth • Street addresses • Private/internal IP addresses • Your own custom terms — add project codenames, client names, or anything else specific to you 100% LOCAL, NO EXCEPTIONS ShadowGuard has no server. Detection runs entirely on your device — your prompts are never sent anywhere for scanning, there's no analytics or tracking, and nothing is ever sold. The only network request ShadowGuard ever makes is to validate a license key, and only when you activate one yourself. You're always in control: every category can be set to Allow, Warn, Redact, or Block from the options page, and you can review exactly what's been caught from the popup at any time.
