The library that works when nothing else does.

A palm-sized box with its own battery and its own Wi-Fi. Any phone can read its full reference library. No internet, no cell service, no app, no subscription, ever.

★ Veteran-owned · Hand-assembled & tested in Texas
The internet goes down. Your phone doesn't have to be useless. GridFall Library gives it a library that can't go offline — because it already is.

What's inside the box

Power it from any USB-C source, join its Wi-Fi, and your phone's browser opens a full field library. Nothing to install. Everything is stored inside the box.

21 full reference books

A complete offline medical encyclopedia, USDA canning & food-safety guides, water purification, home & vehicle repair, radio and power references, and offline Wikipedia's top articles.

A full-US offline map

Every town and road to street level, searchable across 32,000 U.S. towns — no signal required. Type a place and the map flies there.

7 original Quick Guides

Short, plain-language pages written to be read under stress: First 72 Hours, First Aid, Water, Food, Sanitation, Power, Communications.

Built to prove itself

An on-board Device Health page checks the library, maps, storage, and power and shows you green when it's ready. No guessing whether it works.

Its own reserve power

A built-in rechargeable battery keeps it running when the grid goes down. Recharge from any USB-C wall plug, power bank, or solar panel. It sips power; your phone in airplane mode just reads.

Why not just… the internet, or a shelf of books?

Questions people ask first

Does it really need no internet?

Correct — never. The box broadcasts its own Wi-Fi and everything is stored inside it. Your phone shows a "no internet" warning when you connect; that's expected. The only optional internet moment is if you choose to plug in an Ethernet cable for a software update.

What does it cost, and is there a subscription?

Founder's-batch pricing is $239, one time, with the battery included. No subscription, no account, no app. You own the box outright.

Can't I just build this myself?

Yes — if you're comfortable with Kiwix, ZIM files, and a Raspberry Pi, plenty of people do. GridFall is for everyone else. It arrives done and tested, it runs its own Wi-Fi so the whole family can read at once, it has its own battery, and a real person answers if something's off. You're paying for the 20-to-40 hours of work, not the parts.

How is this different from a flash drive full of PDFs?

A flash drive of survival PDFs sounds great until the emergency, when you're scrolling thousands of files for the one you need. This box has seven short guides written for stressful moments, plus one search box that pulls the right page from every book at once. Less digging, faster answers.

When will it ship?

We're sizing the first batch to the reserve list now and building by hand. Reserve your spot and we'll email you the moment units are ready — you'll get first pick before any public listing.

Can I trust the information?

The library comes from well-known public sources: Wikipedia, the USDA, U.S. government works, and other openly licensed references. It's for looking things up — not a substitute for a doctor or emergency services.

What if something's wrong with it?

A real person answers support, and it's covered by a 30-day return window. The box even self-tests: a built-in Device Health page shows you green when everything's working.
