StudyNotesHub – AI-Powered Learning Platform
Inspiration
Engineering students often spend hours searching across multiple websites, Telegram groups, and Google Drive links just to find quality notes, previous year question papers, and study materials. Even after finding the right PDF, understanding lengthy documents and identifying important topics takes a significant amount of time.
We wanted to build a single platform where students can not only access study resources but also interact with them using AI. Instead of switching between different applications, students can upload PDFs or images directly into the chatbot and instantly receive summaries, explanations, important topics, flashcards, and answers to their questions.
What it does
StudyNotesHub is an AI-powered learning platform built specifically for engineering students.
Key features include:
Secure digital notes marketplace
Previous year question papers
University syllabus and study resources
AI-powered chatbot
PDF understanding
Image understanding
AI-generated summaries
Context-aware conversations
Secure cloud storage using Backblaze B2
Admin dashboard for content management
Google Sheets feedback system
Students can upload study material directly inside the chatbot and ask questions such as:
Summarize this PDF
Explain this topic
Generate important questions
Create MCQs
Explain handwritten notes
Translate into simple language
Everything happens inside a single conversation without leaving the platform.
How we built it
The frontend is built using React and Vite, while the backend is developed with Flask and MongoDB.
Backblaze B2 is used as the primary object storage for securely storing purchased PDFs. Files are delivered using secure, time-limited URLs to ensure only authorized users can access premium content.
Cloudinary is used for image management.
The AI chatbot supports document and image understanding, enabling students to interact naturally with their study materials.
Additional services include:
Razorpay for payments
Google Sheets API for collecting feedback
JWT Authentication
Role-based Admin Dashboard
Responsive UI optimized for desktop and mobile
# Challenges we ran into
One of the biggest challenges was integrating secure cloud storage while ensuring that premium PDFs remained protected.
We also worked on handling large PDF files efficiently, maintaining chat context, validating uploaded documents, and improving the overall user experience without introducing additional complexity into the interface.
Building an AI assistant that fits naturally into an educational workflow while keeping the application responsive was another important challenge.
What we learned
During this project we learned:
Secure object storage using Backblaze B2
AI-assisted document understanding
Building scalable Flask APIs
Managing large file uploads
Authentication and authorization
