When the grid goes down, it still has the answers.
A rugged, hand-cranked device holding over a million pages of survival and rebuilding knowledge — searchable by voice, readable in full sunlight, kept current every time you plug it in. No signal. No dead battery. No missing answer.

Works with no signal, no internet, ever.
Never runs out of battery. Crank it back to life.
Thousands of manuals, found by voice in seconds.
Updates itself at home, then goes dark-ready.
Not a gadget. A civilization backup that fits in a pocket.
Every skill to survive the crisis — and the deeper knowledge to rebuild power, water, shelter and medicine after it. Offline, self-powered, always current.
Everything you rely on runs on the grid.
The moment the signal dies, your phone becomes a paperweight. Every answer you've ever needed lives on a server you can no longer reach.
Printed manuals don't die — but they're frozen the day they're printed, and you can't search a bookshelf with one hand on a wound. A crank radio only receives whatever someone else is broadcasting.
The Survival Codex is the one tool that is vast, current, searchable, and self-powered — built to work when everything else has gone dark.

A library that would fill a truck. In the palm of your hand.
The Survival Codex doesn't just help you survive the crisis — it holds the knowledge to rebuild what's lost. Distilled from the world's practical knowledge, compressed, indexed, and made instantly searchable offline.

“Why not a survival book and a crank radio?”
Fair question — we asked it too. A book gives you one author’s few hundred pages, fixed the day it was printed, findable only by flipping. It can’t hold the topographic maps of your region, can’t compute a chlorine dose or a beam load, and can’t tell you what changed last month.
The Codex holds over a million pages — a bookshelf that would fill a truck — answers a spoken question in seconds, carries vector maps of the ground you’re standing on, runs real calculators and diagnostic flows, and refreshes itself every time you plug it in at home. The crank means it outlives every battery you own.
A book is a snapshot. The Codex is a library that stays current — and answers back.
Update at home. Ready in the wild.
PLUG IN AT HOME
Connected, the Codex quietly updates its library and pulls the latest intelligence for your region.
CHOOSE WHAT MATTERS
Pick your region, topics, and update cadence. It syncs only what you select. (First 12 months of updates included; $1/month after that, optional — skip it and the device keeps whatever it last synced.)
GO DARK-READY
Unplug and head out. Everything you need is now offline, searchable by voice, powered by the crank.
Built for the worst day.

E-ink display
Sunlight-readable electronic paper that holds the page at zero power. No glare, no glow, no drain — the screen is still showing your answer a week later.

Voice search
Press the mic, ask the question, get the answer in seconds. Hands full, gloves on, dark — it still works. Or browse the whole index with the D-pad.

Hand-crank power
A built-in crank recharges it — the knowledge never dies with a battery. Tops up over USB-C at home or from the optional solar panel in the field.

Weather sensing
Onboard barometer, thermometer, and humidity sensor read the air around you — and warn you when the pressure says the weather is about to turn.

Quick keys
Four assignable shortcut keys jump straight to your critical pages — bleeding control, water purification, your region map, your family plan. One press, no menus.

Rugged & sealed
A sealed glass-fiber shell built to be dropped, rained on, and carried for years. Deliberately no radio, no speaker, no SOS — it doesn't call for help. It makes sure you have every answer when help isn't coming.
Every page, built for the field.
Actual screens at the device’s real 240×416 e-ink resolution. Dense, cross-referenced, readable in full sunlight — written for the moment your hands are shaking.
Speak the question. One best answer first, ranked results after — entries, decision flows, tables, ID plates.
Vector topo of your region at three zoom levels — water, hazard, and route layers. Not a picture of a map. A map.
Field identification with a verdict you can't misread. Every deadly lookalike gets a plate.
Dense, field-manual writing. Every underlined term links deeper — a million pages, all cross-referenced.
Reference tables and live calculators — dose, dilution, load — computed on-device.
The onboard barometer reads the air and warns you hours ahead — no forecast signal needed.
SHOWN PIXEL-FOR-PIXEL AT THE DEVICE’S NATIVE RESOLUTION · 3.7" E-INK
Support gear. Same discipline.
Heavy Duty Carry Case
A hard, sealed case that takes the knocks so the Codex doesn't. Keep it inside between trips.
Solar Charging Panel
A folding panel that tops the Codex up from daylight — save the crank for the dark days.
Map Packs
Deep vector topo coverage beyond your home region — expedition-grade detail, fully offline.
“We kept asking one question: if everything went quiet tomorrow, what would you wish you had saved? Not food. Not fuel. Knowledge. So we built the device that keeps it — current, searchable, and powered by your own hand.”
Be ready before you need to be.

What exactly is the Survival Codex?
A rugged, hand-cranked handheld holding a vast offline library of survival and rebuilding knowledge, searchable by voice and browsable on a sunlight-readable e-ink screen. It also senses temperature, humidity, and barometric pressure.
Does it need internet?
No. It works 100% offline. It only connects (via USB-C at home) to update its library — then it's fully self-contained.
How does the "always current" updating work?
Plugged in at home, it pulls the latest curated intelligence for your chosen region and topics. Your first 12 months of updates are included; a $1/month plan (launching with the device) covers keeping it current after that. Once you go offline, it holds the most recent version.
How is it powered?
A built-in hand crank recharges it — it never runs out of battery. It also charges via USB-C (and an optional solar panel).
Does it call for help / have GPS / a radio?
No. It has no radio, transmitter, or GPS. It is a knowledge, power, and environmental-awareness device — not a communication or rescue device. (Maps use pre-loaded data; you mark your position manually.)
What's the carry case for?
An optional hard, sealed case for storage and transport — it protects the Codex from impact, grit and water when it's living in a pack, a vehicle or a cache. Keep the device inside between trips. (Take it out of the case to sync.)
Is the information reliable?
Content is curated and distilled from reputable sources, but it is reference information — not a substitute for professional medical care, emergency services, or hands-on training.
Can I cancel my pre-order?
Yes — full refund available any time before your order ships. Email us and we'll take care of it.
