Silverpost
A text, a WhatsApp, an email, a letter. Silverpost tells your mum and dad in seconds whether it is genuine or a scam, and quietly tells you as well.
The apps are in the making. Join the founding families and you will get them first.
The problem
Every Tuesday
Two are junk, one is a pension statement, and one has a date on it that matters. He will get to them at the weekend. He has been getting to them at the weekend since March, and the inbox on the tablet is worse.
Thursday, 6.04pm
A text says a parcel is held and a small fee is due. It arrives on the evening she really is waiting for a delivery, it looks exactly like the real ones, and it wants her card details. She has about thirty seconds to decide, on her own, with nobody to ask.
Sunday, 7.12pm
Hi mum, I have dropped my phone down the loo, this is my new number. It sounds like her. It uses the name she uses. By the time anyone in the family hears about it, the money has gone, and she is too embarrassed to say how much.
Criminals stole £1.28 billion through payment fraud in the UK in 2025, and eight people were defrauded every minute. The ones who lose the most are usually the ones who were certain they would never fall for it. UK Finance, Annual Fraud Report 2026.
How it works
Step one
A text, a WhatsApp, an email, or a picture of a letter. She sends it the way she would send a photo of the dog. There is nothing to log into and no form to fill in first.
Step two
What it is, who it is really from, whether there is a deadline, and what to do next. Written in plain words, with no jargon, and never a lecture.
Step three
Anything dangerous appears in your family feed the moment it happens. You never have to ring and ask whether anything has come. So the whole family gets a second look, the moment it matters.
See it for yourself
An illustration of how Silverpost answers. These are example messages.
This is not your daughter. It is the "Hi Mum" scam.
Do not reply, and do not send any money. Ring her on the number you already have for her, the one saved in your phone. A real daughter will not mind being checked.
Sent to the family feed straight away
Silverpost is a second pair of eyes for the family, not a guarantee. When it is not sure, it says so.
What it catches
Evri, Royal Mail, DPD. A parcel held, a small fee, and a link that is not theirs.
A WhatsApp or text from your son or daughter, from a number that is not theirs.
Penalty notices, parking charges and HMRC refunds, all invented to make somebody panic.
The call or text saying the account is at risk, asking her to move money to be safe.
Insurance and energy letters where the price has quietly risen by a hundred pounds.
The real letters, with real dates, which matter every bit as much as the fake ones.
The promise
What your family sends it stays your family’s business.
Plainly, so you can weigh it up: the reading is done by Anthropic’s Claude, on servers in the United States, under a written agreement with the safeguards UK law requires for sending data abroad. A fully private mode, where letters never leave Silverpost’s own machines, is on our roadmap. We will tell you the day it arrives, and not a day before. It is all set out in the privacy policy.
It is never sold and never used to train AI. The letter is read under contract by our AI provider, we keep the check so the family can see it, and server logs are deleted after 30 days. That's it.
