A Knowledge Assistant for When Shit Hits the Fan

Bookend is the first fully offline knowledge assistant: a complete library and guide that runs entirely on your local machine.
No internet. No subscriptions. No tracking. Just answers.

It fits on a USB drive, works on any computer, and gives you permanent access to humanity's collected knowledge: encyclopedias, medical references, technical manuals, survival guides, and more. Delivered through a conversational, on-device AI assistant.

Whether you're on a camping trip, traveling abroad, living rural, or facing a real emergency, Bookend is there when the grid is not.

Keep one at home. Keep one in your go-bag. Share with family.█
