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.
Text Extraction & Processing – The bot extracts text using LangChain and AI models.
Conversational AI – Users ask questions, and the bot finds answers within the document.
Instant, Contextual Responses – The chatbot delivers accurate responses with citations.

Features & Capabilities

Smart PDF Understanding – AI comprehends complex documents.
Instant Answers – No need to manually search through pages.
Natural Language Processing – Engages users in a human-like conversation.
Multi-Document Support – Handles multiple PDFs for research or business use.
Scalability & Security – Ensures smooth and secure interactions.

Outcome & Impact

Saves time by quickly extracting information.
Makes PDFs interactive and easy to understand.
Improves accessibility for researchers, students, and businesses.
