In development. Early access opening soon.

AI can sound like your daughter and log into your bank.

It writes the email. It clones the voice. And more and more, it runs on the computer in your living room without ever asking you. ImposterShield starts with that last one, because it is the one nobody is checking.

Free scan when we launch. No card. We will not sell your email, ever.

Why we started

The call comes at nine at night.

It is your grandson. There has been an accident, he is scared, 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 him talking in a video he posted two years ago was enough to build it, and the person using it has never met him.

Almost every one of these is stopped by the same thing: a few seconds of doubt before you act. That is the entire job. Not to be clever, just to put something between a very good fake and the moment you reach for your bank card.

What we catch

Three different kinds of fake.

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

Building now

Software that moved in

AI agents that install themselves, watch your screen, click your buttons and sign into your accounts. It is not a virus in the old sense. It behaves like a user, so nothing stops it. This is the one nobody is doing for regular people, so it is the one we are building first.

Building now

Content that was never made

The photo of the damage. The listing that looks too good. A growing number of AI tools now stamp their own output with a signature, and our browser extension reads it and tells you, instead of guessing.

Coming later

People who are not people

Cloned voices and messages written to sound like someone you trust. This one needs a phone app, so it is not in the first release. When it lands it will work by knowing your family's real numbers, not by trying to out-guess a voice clone.

How it works

You should not need to be technical to know you are safe.

  1. Run the free scan

    It looks at what is actually running on your computer right now and where it is sending things. Not a list of file names you have never heard of. A plain sentence about each thing it found and whether you should worry about it.

  2. Add the browser extension

    As you browse, anything that looks machine generated gets flagged before you decide to trust it. The email asking you to move money. The listing with the too perfect photos. The profile with nine hundred friends and no history.

  3. Get told when something changes

    New software that installs itself. Something that was not reading your screen last week and is now. You hear about it the day it happens, not after the money is gone.

  4. Cover the people you worry about

    One account covers your family's computers. If your kid installs something that starts watching the screen, or your dad's machine picks up a passenger, you find out too, not just them.

Who it is for

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

Pricing

The scan is free. It stays free.

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

Planned pricing, and the first release is Windows and Chrome only. The phone app is real on the roadmap but it is not in the first version, and we are not going to charge you for it before it exists. Waitlist members get in first and get launch pricing.

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.

Isn't this just antivirus?

Antivirus was built to recognize known bad files. The thing we are worried 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. A phone version is a different product and we are building the computer one first. 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 published detectors are strong on clean recordings and much weaker on an actual compressed phone call, which is the only case that matters. So we are not going to build our product on that promise. 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.
