I thought this would be for contacting authors or chatting about the paper with other readers, but apparently RAG here is a new important TLA to take note of, meaning chat bot. You need to enter an API key from "Open"AI to use the service and it's about it answering your questions about the paper

Oops sorry for the miscommunication, actually you don't need to enter an API key for now. Feel free to just try it out!
