Technology Stack
Project Overview
ChatPDF is an AI-powered document assistant that allows users to upload PDFs (on Cloudinary) and interact with them using natural language queries. Built with Next.js, it leverages Pinecone for storing embeddings of documents, Langchain to use AI Integrations for example Google Gemini AI or ChatGpt to enable seamless document analysis, key information retrieval, and summarization. The app is designed for students, professionals, and researchers who need quick insights from large PDF documents.
Objectives
The project aimed to achieve the following:
- Develop a Full-Stack AI-powered document assistant Platform – Enable users to upload their PDF files and enable seamless document analysis, key information retrieval, and summarization with the power of AI.
- Implement Secure Authentication – Use Clerk to support email/password and social logins (Google, Facebook) with profile management.
- Implement Subscription Plans – Use Stripe to support Free & Pro-tier with monthly subscription plans that user can manage through Stripe Portal.
- Enable AI-driven interactions – Use Pinecone to store embeddings of documents for fast semantic search and LangChain to integrate Gemini for answering user quires.

Conclusion
Building ChatPDF was an invaluable experience in developing an AI-driven document assistant, enhancing my expertise in Next.js, AI-powered retrieval, and cloud-based storage. This project allowed me to integrate Langchain and Pinecone for intelligent document search, leverage Google Gemini AI for interactive responses, and ensure secure authentication and storage with Clerk and Firebase. Implementing Stripe for subscription management and Cloudinary for file handling further solidified my understanding of scalable and production-ready applications.
Through this project, I honed my skills in building responsive, AI-powered, and user-centric applications, reinforcing my ability to create efficient, real-world solutions that enhance productivity.
