In development. Waitlist open.

It tells you what's fake.

ImposterShield lives in your browser. The photo that was AI-made. The email a machine wrote. The listing that was never real. You get a plain flag on each one, right where you are looking, before you trust it.

Waitlist members get it the day it launches. We will not sell your email, ever.

Fake

The photos on this rental listingMade by an AI image tool. The files say so themselves.

Fake

This email from "your bank"Machine written, and the link does not go to your bank.

Real

Your daughter's vacation photosStraight off a camera. Nothing to worry about.

This is what the flags look like. Plain sentences, right on the page, as you browse.

What you get

One extension, one scan, one set of alerts.

Every piece is labeled with where it really is. We would rather tell you what is not built yet than let you find out after you have paid.

The browser extension

Flags AI-made photos, emails, and listings while you browse, before you decide to trust them. The rental listing with too-perfect photos. The email asking you to move money. This is the heart of it.

The free computer scan

Fakes do not just live on web pages. AI agents can install themselves on your computer and watch your screen, and antivirus walks right past them because they act like a normal user. The scan finds them and says so in plain English.

Family alerts

One account covers five computers. If something moves in on your mom's laptop or your kid's PC, you find out the same day, not after the money is gone.

Why we started

The call comes at nine at night.

It is your grandson. There has been an accident, he needs money tonight, and he is begging you not to tell his parents.

It is his voice. The pauses. The way he says your name.

He is not on the phone. Thirty seconds of a video he posted two years ago was enough to build it.

Almost every one of these scams is stopped by the same thing: a few seconds of doubt before you act. That is our whole job. Put something between a very good fake and the moment you reach for your bank card.

How it works

Three steps. None of them technical.

  1. Add the extension to your browser

    One click. From then on, anything that looks machine made gets a plain flag while you browse, before you trust it.

  2. Run the free scan

    It looks at what is running on your computer right now. You get a short report where every line is a plain sentence: what it is, and whether you should worry.

  3. Let it keep watching

    New software that installs itself, or something that starts reading your screen this week, and you hear about it the day it happens. Cover your family's computers on the same account.

Who it is for

Regular people with a lot to lose and no IT department.

The grandkid-in-trouble call is not an impression anymore. It is their actual voice.

Bank, business, email, taxes. One machine, and no idea what is on it.

Pricing

The scan is free. It stays free.

You should be able to find out what is on your computer without paying anyone. The part you pay for is us watching it so you do not have to.

Questions

The honest answers.

Can I buy this today?

No. ImposterShield is in development and nothing is for sale yet. The waitlist is real and the early access group is small on purpose. If you would rather we told you it was ready, this is probably not the company for you.

How do you know what's fake?

A growing number of AI tools stamp their own output with a signature, and the extension reads it instead of guessing. Where there is no stamp, we look at the things scammers cannot easily hide, like where a link really goes. When we are not sure, the flag says so. We will not pretend to a certainty we do not have.

Isn't this just antivirus?

Antivirus recognizes known bad files. The thing we worry about is not a file, it is behavior. Software that reads your screen, moves your mouse, and signs into your accounts looks exactly like a person using the computer, which is why it walks straight past the tools you already have.

Do you read my files, photos or messages?

The design goal is no. The scan looks at what programs are running and what they are connected to, not the contents of your documents. When we publish exactly what gets checked and what leaves your machine, waitlist members see it first.

Mac or Windows?

Windows first, Mac after. The browser extension is planned for Chrome and Edge at launch.

Is there a phone app?

Not in the first release, and we want to be straight about why. Phones deliberately stop any app from seeing what other apps are doing, so the scan that makes this useful on a computer is not something we can simply move to a phone. When the phone app comes, it will work by knowing your family's real numbers and telling you when a call is not from one of them.

Can you really tell if a voice is fake?

Not reliably, and anyone who tells you they can is selling something. The thing that genuinely stops these calls is hanging up and dialing the number you already have saved, and that is what we intend to automate.

Who is behind this?

A small independent team in Utah. Not a private equity rollup of three antivirus brands you have already heard of.
