# Creating Apps For LLMs ChatGPT apps are conversational experiences that extend ChatGPT through tools and custom UI widgets. They're built as MCP servers invoked during conversations. ⚠️ The app is consumed by two users at once: the **human** and the **ChatGPT LLM**. They collaborate through the widget—the human interacts with it, the LLM sees its state. Internalize this before writing code: the widget is your shared surface.
