AIwolfie/WebUI ? reverse-engineered prompt

Build me a private local AI chat web app that feels like ChatGPT and runs right in the browser.

I want a clean dark and light interface where I can chat with any OpenAI compatible provider, save multiple API keys and endpoints, switch models from a dropdown, and keep separate conversations that are searchable and easy to edit or regenerate. It should stream replies as they come in, support markdown and code blocks nicely, and store everything locally in the browser so my chats and settings stay on my machine.

Please also include a simple local Python server so I can run it on localhost and avoid browser CORS issues when connecting to different providers. Make it easy to start on Windows too. A settings panel for custom system prompts and a few preset personas would be great, along with export and import for backups. If you need to look up current docs online, go ahead.
