Kovcheg (Ковчег) — offline answers from your own documents
When the network is down, the knowledge you need is often already on a disk: first-aid manuals, field guides, equipment docs. Kovcheg finds the passages that answer your question and shows exactly where they come from. When the library has nothing relevant, it says so instead of guessing.
This page runs the real kovcheg Python package in your browser (Pyodide) in its keyword mode, with no AI model: the mode that works on any computer. Nothing is sent to a server, including documents you upload. GitHub · MIT
Three short summaries of public CDC, FDA and FEMA guidance: safe drinking water, food during a power outage, an emergency kit. Demo content, not authoritative guidance.
