Now in private alpha · Protecting Gmail today
Your own security team.
Real-time, enterprise-grade cybersecurity for consumers and small businesses, managed by AI. FoilerAI checks every email before you see it, tells you in plain English what it found, and takes scams out of your inbox before the moment that matters.
Fraud has gone industrial, and AI is its force multiplier.
$16.6 billion in fraud and scam losses was reported by Americans to the FBI in 2024, and it grows every year.1
AI has removed every old giveaway. Scam emails are now written perfectly, voices are cloned from seconds of audio, video can no longer be trusted on sight, and fake sites are built in minutes. A fake invoice. New bank details from a supplier you have paid for years. A sign-in page that looks exactly like your bank's.
Antivirus asks whether a file is a virus. That is not how people lose money. People lose money by believing an email, a text, a call, an invoice or a video. The attack moved from the machine to the person, and the protection sold to people never moved with it.
Small businesses carry the same risk with higher stakes: a five-person firm is one convincing fake vendor invoice away from a five-figure loss, with nobody on staff whose job is to catch it.
Large companies are protected because they have teams of security experts whose only job is to defend them. People and small businesses have never had that team. FoilerAI is that team, working for you.
How it works
Connect your Gmail
Sign in with your Google account. There is nothing to install.
Every email is checked first
Before a new email reaches your inbox, FoilerAI checks who really sent it, where its links really go, what is inside its files and pictures, and what it is asking you to do.
Safe email arrives untouched
Most of your email is fine, and it arrives exactly as it was sent.
Risky email arrives protected
You get a protected copy. A banner at the top says what the email is and what to do, and notes sit right beside the words, links and files that raised a concern. Links and files open only through our safe view.
Scams are taken away
A scam goes straight to Trash, and you get a short note telling you FoilerAI stopped it. Foiled.
What FoilerAI checks
Where links really go
Fake sign-in pages, lookalike websites and known dangerous sites. Every link is checked again the moment you click it.
Files and pictures
Viruses, files pretending to be something else, and QR codes or fake invoices hidden inside pictures.
What it asks you to do
Requests to pay, to sign in, or to call a number. Every scam needs you to do one of these.
Changed bank details
When someone you pay suddenly sends new account details, FoilerAI notices. It is one of the costliest scams there is.
Whole conversations
Replies and forwards are checked too, including earlier messages that someone quietly changed.
Plain English, every time
No jargon and no codes. FoilerAI tells you what it found and what to do about it, in words anyone can follow. Every warning points at the exact thing that worried us, so you can see for yourself.

Our promises
- Your data. Never sold, never monetized.
- We never connect to your bank and never ask for your bank sign-in.
- We read your email only to protect it.
- Leave any time. Disconnecting takes one click and deletes our access to your mailbox.
Where we are going
Gmail is first. The goal is protection on every screen you own: email, texts, calls, web browsing, QR codes, invoices and payment requests, and fake photos, video and audio, each answered with a verdict, a plain-English reason and an action taken on your behalf.
- Your personal baseline. FoilerAI learns the banks, billers and vendors you deal with, so it can say "this invoice from your plumber shows different bank details than the last three".
- Protect the people you love. Protect a parent's phone, and you get the alerts.
- For small businesses. FoilerAI learns your vendors and their payment details and flags any change before money moves.
- Next up. A Chrome extension that checks websites as you browse, and notifications on your iPhone and Mac.
Built by a security leader
FoilerAI was founded by Jack Miller, a three-time enterprise chief information security officer with thirty years in cybersecurity. He built and ran the kind of security operations that protect large companies. FoilerAI brings that protection to everyone else.
