Creating an Interactive ChatGPT-like Chatbot in Node-RED

I want to build a ChatGPT-style interactive chatbot inside Node-RED that allows users to type a question and get smart, conversational replies — just like the real ChatGPT interface.

The chatbot should connect directly to the OpenAI API using my API key and display responses inside the Node-RED Dashboard 2.0 UI.

My question:
:backhand_index_pointing_right: Which nodes should I use to build this interactive chatbot interface?
:backhand_index_pointing_right: How can I handle user input dynamically (instead of inject node)?

This is probably a good place to start - node-red-dashboard-2-ui-chat (node) - Node-RED

You haven't really said why you want to use Node-RED for this rather than simply using one of the many existing interfaces for interactive AI chat? If you could explain that, we would be able to give better advice.

Do you anticipate this interface to be used by multiple people? What distinct capabilities would you want it to have that would differentiate it from existing interfaces? Where would Node-RED actually play an active part?
