Your own copy of the answers, for the day the cloud goes quiet.
US$29 Your own offline AI, Wikipedia, a medical reference and maps + bonus playbookGet it →Prefer it on a USB, ready to plug in? Join the waitlist.
Your own AI assistant on your own laptop, with Wikipedia and WikiMed beside it to check what it says. If AI or the cloud goes down or goes wrong, you're ready. If that day never comes, you still own a very good offline library, and you have 30 days to change your mind.
What's included
Your own AI and library, set up for you.
You could find and set up every piece yourself. Most people never will. We did the work, tested it and packed it into one installer. One evening and you're done.
Your own offline AI
A small open-licence model set up to run on your laptop. Plain-English questions, with Wikipedia beside it to check answers.
Wikipedia, offline
Every English article with images, searchable from one box. The Kiwix build we test is 119 GB.
WikiMed
The medical encyclopedia for reference reading when you can't get online. It is not medical advice: in an emergency call your local emergency number.
USNZ map pack
From OpenStreetMap: roads, tracks, towns and landmarks, readable with no signal.
The playbook
"When the internet goes down": a short guide to the first hour, day and week of an outage, as a PDF to print.
A year of updates
We email you each time there's a new tested build. One click to update.
113 incidents posted by OpenAI, Claude, Cloudflare and GitHub on their own status pages in the last 30 days. The Offline Brain doesn't need any of them.
