Introducing DocPilot, an AI-driven tool that turns PDF documents into interactive experiences. With DocPilot, users can upload a PDF and instantly ask questions, receiving relevant answers in real time. We’ll explore the technology behind it, the challenges of processing PDFs, and how DocPilot makes document interaction smarter and more efficient.

To build DocPilot, I used a combination of technologies:

• MongoDB: A flexible, NoSQL database that stores and manages the application's data, including user-uploaded PDFs and their metadata.
• Node.js with Express: This backend framework serves as the core server, handling API requests, managing user sessions, and integrating with external services.
• React: A modern frontend library that powers the user interface, providing a smooth and interactive experience for users to upload PDFs and ask questions.
• Pinecone: A vector database that indexes and retrieves relevant information from the PDFs by converting text into vectors, enabling quick and accurate search results.
• OpenAI API: The core AI component that processes user questions and generates intelligent responses by understanding the content of the uploaded PDFs.

Together, these technologies create a seamless platform that allows users to interact with their documents in a completely new way.
