Mum booked a table for six at Luma for Saturday.

Mum is a private assistant in Signal. It handles the bookings, the trips and the errands. Everything it knows about you is encrypted, and only you can read it.

File 01 / What Mum did this week

It did the errands. We got the black bars.

Trips
Booked four nights in Porto for you, Inés, Tom and Sam, under €180 a night.
Tables
Reserved a corner table for six at 7:30 on Saturday.
Commutes
Rerouted you via bus 46 when your line was suspended.
Shopping
Reordered the usual coffee for £4 less, arriving Thursday.
Research
Compared three broadband deals and recommended the second.

Mum asks before it spends anything. Say no and nothing is charged.

File 02 / Privacy

Four things we can’t do.

01

Read your messages.

They are encrypted on your phone and stay that way to the machine that does the thinking, and all the way back.

02

Log in to your Mum.

There is no staff login, no back door and no record of what was said. We have nothing to sell, leak or hand over.

03

Train an AI on you.

What you tell Mum never trains a model. Mum remembers it for you and for nobody else.

04

Swap the software quietly.

A machine has to prove exactly what it is running before it is given anything of yours. Read how it works.

File 03 / Group chats

Drop Mum in the group chat. Type @mum.

Mum joins a Signal group like anyone else and only answers when it is asked. It sees the chats it has been added to and no others.

Inés
are we doing Porto or not
Tom
yes. 14th to 18th. a terrace please
You
@mum four of us, near the river
Mum
Three that fit. Shall I hold the second?
File 04 / Mum to Mum

Your Mum calls their Mum.

Finding an evening that suits two people usually means showing each other your calendars. Your Mum asks theirs instead. Each checks in private and only the answer comes back: Thursday at eight.

File 05 / On the web

Websites can’t tell which one is yours.

When Mum looks something up, compares prices or makes a booking, the website sees one more ordinary visitor. It does not learn who sent it, unless you have asked Mum to sign in as you.

File 06 / Pricing

Free. That part isn’t redacted.

Every plan gets the same private Mum. The only difference is how much it can do for you each week. Allowances reset every week.

Free
$0
per month
100M tokens a week. Everything Mum does.

Pro

File 07 / Questions

Answers, in full.

Do I need Signal?+

Yes. Mum lives in Signal, the free private messenger for iPhone, Android and desktop. If you already use it, you are one invite away.

Can Mum see my other chats?+

No. Mum sees your own chat with it and any group you add it to. Nothing else.

What is a token?+

A small piece of text, about three quarters of a word. Mum counts what it reads and writes for you, including web pages it reads while working. The free plan includes 100 million a week.

Can Mum spend my money?+

Only with your say-so. Mum asks in the chat before every payment. If you decline, nothing is charged.

Does Mum learn from my conversations?+

Mum remembers what you tell it, for you alone. None of it is used to train any AI model.

How do I know it is private?+

You do not have to take our word for it. The machines prove what they are running before they receive anything of yours, and Signal warns you if Mum’s identity ever changes.

Get on
the list.

No email, no name. Mum will message you on Signal when there is room.
