This paper presents a state-of-the-art system that is intended to facilitate natural language interaction with PDF documents. Leveraging the powerful Retrieval-Augmented Generation (RAG) algorithm, the solution seamlessly integrates information retrieval and generative language models to generate precise and context-sensitive responses. The operation starts when a user uploads a PDF file. The system proceeds to process the file, breaking it down into bite-sized text chunks that are kept organized for easy retrieval. Upon the submission of a query by a user, the RAG algorithm locates the most applicable parts of the document and uses a generative language model to build an understandable and accurate response. By combining the LangChain platform with the RAG approach, this paper introduces an effective tool for extracting precise information from long PDF documents efficiently. Its capacity to provide relevant and accurate responses makes it particularly valuable in education, research, and documentation professions where immediate access to accurate information is paramount.
