Every day, thousands of people fall victim to phone scams. SafePhrase was created to stop those scams before they happen.
Using advanced AI phrase detection, SafePhrase recognises the language scammers use — and instantly alerts the user before they share sensitive information.
Designed and developed in the UK by TrustCheck Technologies Ltd, SafePhrase works completely offline, with no data connection and no app required.
SafePhrase™ (sometimes written as “Safe Phrase”) is a registered brand of TrustCheck Technologies Ltd.

The Real Problem SafePhrase Solves
Even the smartest minds can freeze for a second. SafePhrase unfreezes them.
Most people think scams are a problem of intelligence.
They’re not. They’re a problem of emotion — of being caught off guard, flattered, frightened, or hurried at just the wrong moment.
SafePhrase isn’t about replacing your judgment. It’s about protecting you in that one critical second — the second when a voice sounds “official,” and your instincts freeze.
By detecting the subtle phrases scammers use to manipulate trust, SafePhrase acts like a calm, rational friend — one who taps you on the shoulder before you do something you’ll regret.
Because in the battle between fear and reason, even the smartest minds can lose.
SafePhrase makes sure they don’t.
How SafePhrase works
SafePhrase is a small, standalone device that listens only during your phone calls. It can be used with both Mobile Phones (Cell Phones) of Landline Phones.
It uses built-in AI to recognise scam language patterns — the specific phrases scammers use to trick people into giving away money or information.
When a suspicious phrase is detected, SafePhrase instantly vibrates to warn the user — before they reveal any personal or banking details.
SafePhrase works completely offline, requires no app or internet connection, and protects users in real time.
A Note from the Founder - Dominic Gilbert
SafePhrase was born from frustration - and from seeing too many people fall victim to phone scams that could have been stopped.
I wanted to create something simple, human, and independent - a small device that listens, protects, and quietly looks out for you. Not an app that sells your data or a subscription that forgets you once you’ve paid, but a real, physical safeguard that anyone can use.
I’m not a tech giant. I’m just someone who decided that enough was enough - that if the technology exists to stop scams, it should be used to protect ordinary people, not exploit them.
SafePhrase is my way of making that happen.
It’s a small step toward restoring trust in the everyday act of answering the phone.
