The software
Download it from GitHub and load whatever library you like. Free forever, on your own machines.
Product № 002 · Available now
Your offline library, answered. Load it with reference books — Wikipedia, medical encyclopedias, your own manuals — then ask questions in plain language. Every answer cites the exact passage it came from, and after setup it never touches the network.
What it does
Search engines need the internet. Chatbots need the cloud and make things up. ZIM Librarian needs neither — it answers from the books you gave it, shows you exactly where each claim came from, and stays honest about what the sources don't say.
Type a question the way you'd ask a person. Answers come strictly from your loaded library — not from the model's imagination.
Every supported claim links to the exact source passage, highlighted. Anything the sources don't back stays visibly uncited.
No telemetry, no cloud, no accounts, no update checks. The network is touched only when you ask for a download.
Wikipedia, the WikiMed medical encyclopedia, StackExchange, DevDocs, Gutenberg — anything from library.kiwix.org, plus your own documents converted in.
Desktops, laptops, and phones — verified with full on-device AI answers on a $50-class Android handset.
AGPL code, and the default model has open weights and open training data. Swap in any GGUF model you prefer.
Built for the places work actually happens: clinics past the end of the grid, relief teams, ships at sea, crews in dead zones. If your people need answers where there's no signal, this is for them.
