tl;dr: Survival LLM is a free, open-source offline AI assistant bundled with an emergency reference library (FEMA/CDC guides, medical references, wikiHow, iFixit, and ~930,000 Wikipedia articles) that runs locally on Mac or Windows. It auto-selects a model based on available RAM—ranging from IBM Granite 4.2 8B (16GB) up to NVIDIA Nemotron 3.5 Super (128GB+)—and cites sources with every answer so users can verify claims. Everything runs without internet after setup, with no tracking, and supports adding your own PDFs and documents to the searchable corpus.
