renaldiangsar/Customer-Support-RAG ? reverse-engineered prompt

Build me a customer support chatbot web app that lets users ask questions about a product, buying process, returns, and anything else related to their purchase.

I want it to work from uploaded PDF documents, so the chatbot can answer from the company’s own support info instead of making things up. It should also remember earlier parts of the conversation, so follow up questions feel natural.

Make it a simple Streamlit app with a clean chat interface, and use a RAG setup with LangChain, ChromaDB, Groq, and Hugging Face embeddings. Please include a way to load the PDF knowledge base, chat with the bot, and keep the conversation history. Use the API keys from a .env file, and if you need to check current setup details or docs online, go ahead and do that.

Keep it easy to run locally and make the experience feel like a real customer support assistant.
