# Survival LLM A free AI assistant and survival library that runs entirely on your own computer and works with no internet. Ask it how to keep food safe in a blackout, treat a burn or purify water: it searches an offline library of medical, emergency, how-to and encyclopedia articles, answers from what it finds, and shows you the exact passage each answer came from. - **Offline and private.** The AI model and the library live on your computer. Your questions never leave it, and once set up it works with the internet off.

- **Add your own files.** Your files, at the top, takes PDFs, Word documents, EPUB ebooks, web pages and text files (drop them on the window or choose them), so the AI can search your generator's manual, your medicines list or your family's emergency plan along with the library. They stay on your computer, in the `Survival LLM Files` folder in your home folder; files you put in that folder, or change there, are picked up on their own. It can't read scans or photos of pages yet.

- `library/myfiles.py` reads the person's own files into a small index of their own (kept with the app's settings) and searches it together with the library. - Everything except Ollama, the app window (pywebview), PDF reading (pypdf) and checking web certificates with the system's own store (truststore) is the Python standard library. ## Run from source ```bash python3 app/server.py # the app in its own window (needs `pip install pywebview pypdf truststore`; else it uses your browser) python3 app/server.py --browser # in your web browser instead

python3 chat.py "How long is fridge food safe in a blackout?" # terminal; --model NAME picks a model ``` The library is looked up at `$SURVIVAL_LLM_LIBRARY`, then `~/Survival LLM Library`, then `library.noindex/` next to the code. Without a built-in engine, the app uses an Ollama you have installed (`ollama serve`). `python3 tests/run_all.py` checks memory and the handling of what models write (forget requests, notes about different people, Sources lines), with a stand-in for the model: no Ollama or library needed. Run it after changing `memory.py` or

部署要求

支持 macOS 14 或 Windows 10/11 64位，需约8GB内存以上，磁盘空间根据模型和库大小而定。

查看 README 依据

your computer and internet speed (the biggest AI model is 80 GB); you only click for about 5 minutes. **Mac** (Apple Silicon, macOS 14 Sonoma or newer) 1. Download `Survival-LLM-mac.zip` and double-click it to unzip. Move **Survival LLM** to Applications if you like. 2. Double-click **Survival LLM**. The first time, macOS says it can't verify the app, because it isn't sold through Apple. Click **Done**, open **System Settings > Privacy & Security**, scroll down to "Survival LLM was blocked", click **Open Anyway**, and confirm with your password. You only do this once.

**Windows** (10 or 11, 64-bit) 1. Download `Survival-LLM-windows.zip`, right-click it and choose **Extract All**. (Running it from inside the zip doesn't work.) 2. Open the extracted **Survival LLM** folder and double-click **Survival LLM.bat**. If Windows says it protected your PC, click **More info**, then **Run anyway**. **Then** the app opens in its own window and walks you through setup: 1. **AI engine:** built into the Mac app. On Windows, one click downloads it (Ollama, 1.6 GB). 2. **AI model:** it suggests the best one for your computer's memory (below) and downloads it.

`~/Survival LLM Files`; keep that folder if you want them. The app's own settings are in `~/Library/Application Support/Survival LLM` on a Mac, and in `%APPDATA%\Survival LLM` plus the AI engine in `%LOCALAPPDATA%\Survival LLM` on Windows. ## Which model your computer gets The app checks your memory and suggests a model. More memory, smarter model. | Your computer | Model | Download | |---|---|---| | Mac with 128 GB or more | NVIDIA Nemotron 3.5 Super (`nemotron-3.5-super:120b-a12b-nvfp4`) | 80 GB | | Mac with 32-96 GB | Qwen3.8 27B (`qwen3.8:27b-mlx`) | 18 GB |

Gemma 4 E4B (`gemma4`, 10 GB) is offered as a faster option for 16 GB computers. Computers with 8 GB can still search the library; no model we tested was both small enough and safe enough to recommend for them. ## How the models did
