atomicbot-ai/atomic-chat ? reverse-engineered prompt

Build me a local AI chat app that runs private on my computer and works offline.

I want a clean chat experience where I can load open models from Hugging Face, switch between local and cloud providers, and keep all my conversations on my machine. It should also expose a local API that works like the OpenAI API, so other apps and agents can point at it easily.

Include a sidebar for chats and projects, support custom assistants with their own instructions, and add a tools area where I can connect MCP servers and launch popular coding agents from the app. I also want an artifacts panel that can preview simple web code like HTML, CSS, and JavaScript, with options to copy or download it.

Make it feel polished and modern, with support for desktop first, and if you need to check current docs online for anything, go ahead.
