use-ash/apex ? reverse-engineered prompt

Build me a self hosted AI chat app that I can run on my own server and use through a web dashboard, with a clean mobile friendly interface too.

I want to switch between different models in separate chats, including cloud models and local ones, and have the app remember important things across sessions so I do not have to repeat myself. It should support custom slash commands or little skills I can drop in easily, plus a way to search past conversations and recover old context. I also want an admin area where I can see health, sessions, logs, and manage credentials. Make it secure by default, with HTTPS and certificate based access for private use. If you need to look up current docs online for any of the model connections, go ahead and do that.
