Librarian, not oracle
You get citations you can open — not invented medical or survival facts.
Ark
Your library. Offline. Cited.
Ask from your phone over the Ark hotspot. The case can stay closed. Answers come from real packs on the device — no cloud required.

Like Alexandria — carried with you
The Library of Alexandria gathered knowledge so it could be found again when it mattered. Ark is built in that spirit: not a chatbot that invents answers, but a rugged vessel for curated works you can open, cite, and trust — a working collection you carry when the network is gone.
How you use it
Phone-first. Join the hotspot, ask in Guide, read the source — then a short grounded summary.
- Join Ark Wi‑Fi
Connect your phone to the device hotspot. Leave the case closed if you want.
- Ask in Guide
Medicine, plants, repair, outdoors — the librarian retrieves from packs on disk.
- Read source, then summary
On medical and hazard topics, the original source appears first. You are never asked to trust a model's memory alone.
- Days of power, with a solar recharge path
- Expandable library storage for the packs you choose
- Optional mesh and field radios on Expedition
Librarian, not oracle
Critical answers point to real pages. Packs you can open and verify — free open volumes and Ark exclusives.
