Multi-Turn Document Q&A System with LlamaIndex

In this lesson, we will build an interactive system that allows users to upload PDF documents and ask natural language questions about their content. The system will retrieve relevant information from the uploaded documents and generate accurate, conversational answers.

In addition to answering individual questions, the system will support multi-turn interactions by remembering prior queries. It will also include the ability to summarize an entire document and display internal reasoning steps—allowing developers or users to understand how each response was generated.

This type of document-aware assistant is useful in real-world scenarios such as reviewing lease agreements, insurance policies, academic syllabi, or company procedures.
