Give it power.
Connect the power supply, or use the rechargeable battery edition. The Raspberry Pi starts the local library and its Wi-Fi network.
How it works
Prepper Buddy creates a local Wi-Fi network. Your phone or computer uses that network to read what’s saved on the device.

Connect the power supply, or use the rechargeable battery edition. The Raspberry Pi starts the local library and its Wi-Fi network.
Open Wi-Fi settings on your phone, tablet or computer. Choose the device’s network. If your phone says there is no internet, choose to stay connected.
The current setup starts with open Wi-Fi. An optional network password can be set inside the library.
Type this local address into your browser’s address bar. Search, open a guide or read a saved reference. Keep the device powered on and stay on its Wi-Fi.
Our interactive demo lets you try searches and read field guides. On the device, the full manuals, maps and video files open from local storage.
Open the working demoThe device’s saved library works without internet or a cellular plan. Power it on, join its local Wi-Fi and use your browser. This public website and its demo are separate from that local library.
Use a device with Wi-Fi and a modern browser. Join “Prepper Buddy,” stay connected when your phone says the network has no internet, then open 10.42.0.1. There is no app-store installation.
Both planned editions use a Raspberry Pi 4B with 4 GB RAM and 256 GB storage, with the same library. The $499 edition adds a rechargeable battery. Final case, battery specifications and package details will be published before orders open.
The planned device prices are one-time purchases: $399 or $499 with the battery. Ordering is not open yet. Shipping, tax and purchase terms will be shown before checkout becomes available.
The current build provides an 8 GB shared-document upload quota on the Pi. Shared files are readable by people connected to it. Personal Vault stores password-protected, encrypted documents in your own browser; keep backups of important files.
No. The maps and references are saved snapshots. They do not show current closures, weather, evacuation orders or live navigation. The library includes full English Wikipedia text and a separate Simple English edition with pictures.
The library uses local search and saved-source answers. Answer quality is still being refined. It is not sold as unrestricted ChatGPT running on a small computer. You can open the original saved material directly.
Not yet. This is a coming-soon launch page. The notification form does not reserve a unit or charge a payment. We’ll publish availability and delivery details when ordering opens.
