ekhos-ai/ollama-portable — reverse-engineered prompt

Build me a portable local AI chat app that I can unzip onto any folder or even a USB drive and just run, with no install, no admin rights, and no system changes. I want a simple web chat interface for talking to local models on my own machine, and it should open the chat automatically when I start it. On first launch, have it grab the local model runner and a default Gemma 4 model for me, then work fully offline after that with all models, settings, and chat history saved inside the same folder.

Please make it work on Windows and Mac with simple start and stop scripts. It should stay isolated so it does not mess with any existing local AI setup on the computer. Also include a basic settings page where I can see the current model and download or switch to other models later.

Keep the setup feeling dead simple and polished. If you need to, look up current docs online and wire everything together end to end.
