Clotr Antibody

Scammers don't need to break into your computer if they can get you to hand something over: a code they texted you, the numbers on your card, gift cards. Clotr Antibody helps you at that moment. It's free, and it all happens on your own computer.

Not out yet: it's coming in Clotr's next update. This page shows what's planned, and details may change before then.

An AI chat with a message saying someone from the bank wants the 3 numbers on the back of a card. Clotr's note in the corner: Your message contains Card Security Code (•••). Who asks for the 3 numbers on the back of your card? Not your card company: it already has them. Type them only into a checkout page you opened yourself. Buttons: Leave it in, Hide it.

Who really asks for these

Banks, couriers and tech support don't call or message you to ask for any of these. Scammers do. When you're about to send one, Clotr's warning will say who really asks for it.

  • A code that was texted to youOnly scammers ask for it in a call or a message: with it, they get into your account. A code your bank texts you is for typing into your bank's own app or website, never into a chat or to someone who messaged you.
  • The 3 numbers on the back of your cardYour card company never asks: it already has them. Type them only into a checkout page you opened yourself.
  • Gift card numbersNo real business or government agency will ever tell you to pay them with a gift card. Only scammers do.
  • A code that lets someone into your computerReal tech companies don't call or message you about a problem with your computer. Fake tech support does.
  • Your passwordsThey're the keys to your accounts. Nobody else needs them.

A text about a parcel that's stuck? That's a common trick too. Check on the courier's own website or app, never through the link in the text.

A second look: Is this a scam?

Got a text, an email or a chat message that worries you? Paste it into Clotr's Is this a scam? page. Clotr will point out the warning signs it knows, like rushing you or asking for a code, and say what each one means.

It will never tell you a message is safe: scams change, and no list knows them all. Before you answer, call the company on a number you already know, like the one on your card, and talk to someone you trust.

What you paste stays on your computer, and Clotr forgets it when you close the page.

Clotr's Is this a scam? page: Clotr found 4 warning signs, each marked in the message: the fraud team at Anytown Bank, right away, the 6-digit code we just texted you, and don't tell anyone at the branch, they may be in on it.

30 days of stronger settings after a scam

Just been scammed, or nearly? Scammers often come back, sometimes pretending they can get your money back. For 30 days, Clotr will ask before bank, card and ID numbers, gift card numbers and sign-in codes go out, wherever it's on.

Then it steps down by itself, and tells you. You can set it up for yourself or for someone you help, with a short list of what to do right away.

Practice with made-up scams

Six made-up scam messages, like a call from "the bank" or a "grandson" who needs gift cards. Type the reply you'd give, and the real engine shows what Clotr would catch, with a safer reply and why.

Then a second round: would you send this to a chatbot? Nothing you type is kept. It's good to do together with someone you help.

A card for someone you help

Print a card to keep next to their phone: Never read these out. It lists what scammers ask people to read out, and who really asks for each, in big black print on white paper.

At the bottom there's a space for the name and number of someone to call first. Write those in by hand: Clotr doesn't keep them. In English or Spanish.

The card to print, Never read these out: the code your bank or an app texts you, the 3 numbers on the back of your card, gift card numbers, a code that lets someone into your computer, your passwords and backup codes, and bank, card or Social Security numbers to someone who contacted you first. At the bottom, a space for the name and phone number of someone to call first.

Why on your own computer

  • Your messages stay with you. Clotr Antibody works where you type, so nothing you write or paste is sent anywhere to be checked.

  • One engine. Every part of Clotr shares the same engine, so what it knows about scams is the same wherever you type.

  • Honest about misses. It won't catch every scam. When it misses one, or warns about nothing, please tell me.
