MCP.Pizza Chef: AtomicBot-ai
This app lets you download and run open-source AI models like Llama, Gemma, and Qwen right on your computer or phone, keeping everything private. You can also add your own account keys to use cloud models from providers such as OpenAI, Anthropic, or Mistral when you want extra power. It launches coding assistants such as Claude Code, Cline, and Goose with one click, and it can connect to MCP servers so your chats can pull in extra tools, files, and web search. Free installers are available for macOS, Windows, Linux, iPhone, and Android.

Atomic-Chat FAQ
Do I need to know how to code to use this?

Can I use this to keep my conversations completely private?
Yes — when you use a local model, everything runs on your own computer and nothing is sent to the internet.
Do I need an internet connection?
Only to download a model the first time. After that, you can chat completely offline using models that run on your device.
Do I need an account or a paid key to use it?
