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.

No. It works 100% offline. It only connects (via USB-C at home) to update its library — then it's fully self-contained.

Plugged in at home, it pulls the latest curated intelligence for your chosen region and topics. A $1/month plan (launching with the device) covers keeping it current — your first 12 months are included, and the plan is optional after that. Skip it and the device simply keeps the most recent version it last synced.

A built-in hand crank recharges it — it never runs out of battery. It also charges via USB-C (and an optional solar panel).

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.)

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.)

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.

The Heavy Duty Carry Case and the Solar Charging Panel — both optional, both ship with your device in April 2027. Current pricing is shown on the product page. Map Packs arrive at launch.
