Ollama is a convenient tool for quickly setting up a local LLM. Indeed, every prepper must have it on their system.

The setup of Ollama is unspectacular, and you can simply follow the instructions or use an installable. That should be done in a few minutes. You can then run any of the many available models. Make sure to first start the server (ollama serve) and then load (ollama load llama3.2) or run (ollama run mistral) the model you choose.
