StudyQ: An Intelligent Learning Assistant Based on Gemini AI, Turning PDFs into Interactive Quizzes in Seconds

StudyQ is an open-source AI-driven learning platform. Its core function allows students to upload PDF textbooks and automatically generate intelligent quizzes, study summaries, and progress analyses. It uses a React+Node.js full-stack architecture and integrates Google Gemini 2.5 Flash to generate context-aware multiple-choice questions, helping students efficiently convert static learning materials into interactive content. The project is open-source on GitHub and can be experienced directly online.

The core philosophy of StudyQ is "Upload. Learn. Master.", which aims to address students' need to convert static PDFs into interactive learning resources and optimize the learning process through AI technology.

1. Intelligent PDF Parsing and Quiz Generation

Supports uploading PDFs up to 50MB, uses Gemini AI to generate contextually relevant multiple-choice questions, aligns with the active recall principle, and reinforces knowledge.

2. Learning Progress Visualization

Built-in analysis dashboard to track quiz score trends, learning duration, and knowledge point mastery, helping identify weak areas.

3. Intelligent Summary Extraction

Extracts key insights from long documents and generates concise summaries, suitable for quick review or last-minute exam preparation.

4. Secure Identity Authentication

Uses JWT for user registration, login, and session management to ensure data security and privacy.

Frontend Tech Stack

• React19 + Vite7.3: Component-based development and fast building
• Tailwind CSS: Responsive design
• Axios: API communication

Backend Tech Stack

• Node.js + Express: Lightweight server
• MongoDB Atlas + Mongoose: Flexible storage for user data and quiz records
• JWT: Stateless identity authentication

AI and Deployment

• Google Gemini2.5 Flash: Provides PDF parsing and question generation capabilities
• Deployment: Frontend on Vercel (global CDN), backend on Render (auto-scaling)

StudyQ applies to multiple scenarios:

• Exam Preparation for Students: Convert textbooks/lecture notes into self-assessment question banks
• Knowledge Consolidation: Identify understanding gaps through quiz feedback
• Quick Review: AI summaries help with key point review
• Language Learning: Upload foreign language materials to aid comprehension

Value: Shifts students' cognitive load from "creating learning materials" to "focusing on learning itself", optimizing learning efficiency.

StudyQ is a typical paradigm of AI-empowered education: it does not replace human learning but optimizes the process.

Insights for developers:

• Can use the free Gemini API to build practical AI applications at low cost
• The full-stack open-source feature provides a complete reference for modern web development

This project demonstrates the practical application potential of AI technology in the education field, helping students learn more efficiently.
