// explanation
// eli5Imagine your friend is really smart but sometimes forgets things. RAG is like giving your friend a magical notebook they can look up during a conversation. When someone asks them a question, they can check the notebook for the right answer before responding, so they get it right every time [1][2]. Without the notebook, they might make things up, but with it, they can say 'Let me check my notes' and give you accurate information [4].
