eltatata/Nextjs-langchain-retrievalQA
A chatbot created with Next.js and AI SDK, using Langchain with RetrievalQA to provide information from a PDF loaded into a vector store in MongoDB.
Felipe is an AI-powered assistant designed to help students, educators, or anyone learning about computer science data structures. You provide natural language questions about data structures, and it retrieves precise answers directly from a specialized PDF document. This tool is for anyone needing quick, reliable information on data structures without sifting through textbooks.
Use this if you are studying or teaching computer science and frequently need to look up definitions, explanations, or examples related to data structures.
Not ideal if you need information on topics outside of data structures or require answers generated from a broad range of web sources rather than a specific PDF.
