Library Management System with AI Chatbot

“Code. Compete. Conquer.”

Comment

💡 Inspiration

As students constantly dealing with messy and outdated library systems, we wanted to build a smart, easy-to-use platform that does more than just CRUD operations. We imagined a system that understands what a user is looking for — like a virtual librarian. The idea of integrating an AI chatbot to assist students in discovering books, learning about authors, and answering general queries inspired us to take the traditional Library Management System to the next level.

📚 What it does

This Library Management System is a full-stack web app that offers:

  • Efficient book and user management
  • Borrow/return system with fine tracking
  • Advanced book search, sort, and filter
  • A smart AI-powered chatbot for:
    • Book recommendations
    • Author information
    • General library FAQs

It improves both user experience and librarian efficiency through automation and intelligent interaction.

🏗️ How we built it

We built this system using:

  • Backend: Node.js + Express.js
  • Database: MySQL for structured data storage
  • Frontend: EJS templates, Bootstrap for UI
  • AI Chatbot: Integrated Hugging Face Transformers model using a custom-trained dataset (authors, books, genres)
  • Version control: Git + GitHub

The project was organized into modular routes and views to ensure maintainability and scalability.

🚧 Challenges we ran into

  • Training the chatbot: Fine-tuning the model and formatting training data took more time than expected.
  • NLP complexity: Designing a lightweight yet capable chatbot for the library domain was tough with limited hardware.
  • Integration: Bridging AI responses into the frontend using fetch, and making it feel seamless took effort.
  • Search/filter/pagination: Implementing efficient and user-friendly filtering on large datasets without affecting performance.

🏆 Accomplishments that we're proud of

  • Seamlessly integrated an AI chatbot that feels like a virtual librarian
  • Built a fully working library system with all CRUD functionalities, search, and pagination
  • Designed a clean and responsive user interface using Bootstrap and EJS
  • Learned how to combine traditional web development with modern AI capabilities

📖 What we learned

  • How to integrate AI models (Hugging Face) into full-stack applications
  • Designing a scalable Express.js API with MySQL
  • Using EJS to dynamically render UI components
  • Improving frontend experience with autocomplete and modals
  • Collaborating and iterating fast in a hackathon environment

🚀 What's next

  • 📱 Build a mobile-friendly version of the platform
  • 🧠 Expand chatbot knowledge using larger book and author datasets
  • 🧾 Add book reservation and waitlist features
  • 🔒 Implement authentication and role-based access control
  • 🌐 Deploy the system online for live demo access
