xgoliath/rag-docxguru ? reverse-engineered prompt

Build me a simple web app called DocxGuru that lets users upload PDF files, turn them into searchable chunks, and ask questions about what’s inside.

I want it to feel like a clean chatbot for documents, with a friendly Streamlit style interface, a place to upload one or more PDFs, and a chat area where the user can ask things like “What is this report about?” or “Find the section about pricing.” The app should store and search the document content so it can answer based on the uploaded files, not just guess. Use embeddings and a vector database for retrieval, and use an LLM for the final response. If you need to check current docs for the best setup, feel free to look them up online.

Please make it work end to end, with sensible defaults, basic error handling, and a simple polished UI that is easy to use without any setup beyond running the app.
