Extension Metadata

About this extension
The scam didn't look suspicious. That's why it worked.
A fake bank login looks exactly like the real one.
The "your package is delayed" text opens a perfect copy of the courier's site.
The QR code on the parking meter goes to a fake payment page that keeps your card details. Scammers build these pages with AI now, in minutes, and a careful eye is no longer enough.

GatekeeperAI checks every link before you click it — and every QR code before you trust it.

HOW IT WORKS
  • Open any page and every external link is scanned automatically in the background
  • Dangerous links get marked right on the page: a yellow dashed underline for suspicious, red for phishing, plus a hover warning that explains why
  • Click a marked link anyway and a full-screen warning stops the page from loading
  • Known phishing domains are blocked before the page even starts to load
  • Safe links stay exactly as they are. No clutter, no noise

IT ALSO CHECKS THE LINKS YOU SEND

Writing an email in Gmail or Outlook? If the message you are about to send contains a link that leads somewhere dangerous — say, one you copied from another email — GatekeeperAI warns you before it goes out. You choose: don't send, or send anyway.

WHAT IT CATCHES
  • Phishing pages impersonating banks, wallets, and login screens
  • Quishing — QR codes that resolve to scam or wallet-drainer pages (parking meters, fake menus, "scan to verify" posters), checked by the GatekeeperAI apps on your phone
  • Fake support sites, fake giveaways, fake stores
  • Malware downloads
  • Credential-harvesting forms on look-alike domains

PRIVACY

Only link URLs are sent to GatekeeperAI for scanning. Page content is never transmitted. Scan results are cached on your device for five minutes and the cache never leaves it.

WHAT YOU NEED

The extension connects to a GatekeeperAI Personal account ($24/year or $4.99/month, 30-day money-back guarantee). Sign up at gatekeeperai.app/personal, copy the key from your dashboard into the extension popup, and you are protected — it takes about a minute. If you run the GatekeeperAI desktop app, it can hand the key to the extension for you.

ALSO PROTECTS

Android (scans links and QR codes in every app), iOS Safari, and macOS desktop. One subscription covers all of them.
