The app loads PDF documents, extracts and chunks text, embeds it into vectors, and uses similarity matching to retrieve relevant passages before passing them to a language model to generate answers. It uses LangChain for orchestration, Streamlit for the UI, and OpenAI’s API for embeddings and LLM responses.
