One person started it. Anyone can build it.
Access to knowledge shouldn't depend on a subscription, a cell tower, or someone else's servers staying online.
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
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.

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 SeldonLearn more about the Prime Radiant →
