It started with a question

What happens when the internet disappears?

Not hypothetically. Actually. You're on a boat, or deep in the mountains, or the power's been out for three days. Your phone is useless. You can't look anything up. You can't message anyone. You can't even check a map.

I wanted to fix that. Not with a bunker full of printed encyclopedias, but with something small enough to fit in a backpack that gives you real capability when nothing else works.

What it actually does

A small box that creates its own WiFi network. Connect your phone and get:

Encyclopedia

6 million+ Wikipedia articles, searchable offline

Maps

Navigate anywhere without cell service

AI Assistant

Ask questions, completely private

Messaging

Radio or satellite, no towers needed

No subscription. No tracking. No connection needed.

Who uses it

Sailors Overlanders Hikers Emergency preppers Field researchers Humanitarian workers Remote workers Anyone frustrated by "No Signal"

Why "Mule"?

The practical reason

A mule carries heavy loads across difficult terrain. Reliable. Stubborn. Gets the job done when fancier options fail.

The nerdy reason

Asimov's Foundation series. The Encyclopedia Galactica — all human knowledge preserved for when civilization needs it most.

Fully open source

Everything is documented and available. Hardware designs, software configs, complete build instructions.

Buy one ready-made, or build your own from the blueprints.

For the Foundation fans

The Prime Radiant was Hari Seldon's device for visualizing the mathematical future of civilization — all of psychohistory encoded in a form that could be carried, studied, and protected through the fall of empire.

Mule Cube isn't predicting the future. But it is carrying something worth preserving: the sum of human knowledge, accessible anywhere, dependent on nothing.

"The fall of Empire, gentlemen, is a massive thing, however, and not easily fought. It is dictated by a rising bureaucracy, a receding initiative, a freezing of caste, a damming of curiosity—a hundred other factors." — Hari Seldon
