techjarves/Portable-AI-USB — reverse-engineered prompt

Build me a fully portable private AI assistant that runs from a USB drive on Windows, Mac, and Linux. I want a simple one time setup where I copy the files to an exFAT USB drive, run an installer, pick one or more local AI models, and then launch a chat app from the USB later with no internet needed.

Use Ollama and AnythingLLM like the core pieces. Include a friendly model picker with a few preset choices, including lightweight models for older computers, better quality models, and an option to paste a custom GGUF download link. The setup should save models, chat history, settings, and app data on the USB only, not on the computer.

Make simple launch scripts for Windows, Mac, and Linux. They should start everything, open the chat interface, and shut down safely when the user is done. Please also handle common issues like moved USB paths and failed downloads. Look up current docs online if you need to.
