Build a Powerful PDF Q&A RAG System with Langflow, OpenAI & Chroma DB! (No Code/Low Code Tutorial)

LangFlow is a web tool developed in Python that enables users to build LangChain applications without extensive coding. The tool provides a variety of composable blocks for constructing applications, allowing for the creation of a fully functional chatbot capable of querying a PDF. In this process, the PDF is split into manageable chunks using a recursive character text splitter, stored in a ChromaDB instance, and utilized to supply context for the chatbot's responses without necessitating code writing. This showcases the simplicity and effectiveness of LangFlow for developers.

LangFlow allows users to build applications with minimal coding.
