AI-Powered PDF Chatbot Using Lang-Chain
I developed an advanced AI chatbot that allows users to have conversations with PDFs using LangChain. This project enables users to upload a PDF, extract its content, and ask questions about the document, receiving instant AI-generated responses. Built with Node.js and AI models, the system provides an interactive and intelligent way to engage with large documents.
Project Overview
Reading long PDFs can be time-consuming and frustrating, especially when looking for specific information. My LangChain-powered chatbot solves this problem by enabling users to upload a PDF and chat with it as if they were talking to a knowledgeable assistant. The bot processes the document, understands context, and provides relevant answers, making information retrieval effortless.
How It Works
PDF Upload – Users upload a PDF to the chatbot.

Conversational AI – Users ask questions, and the bot finds answers within the document.
Instant, Contextual Responses – The chatbot delivers accurate responses with citations.
