Demo teaching plateform -- 2

Project Title: AI-Integrated EdTech Platform for "Demo teaching app"
Project Overview:
I want to build a comprehensive EdTech platform (Admin Panel + Student App/Web) focused all subjects. The core USP of this platform is AI integration for automated test generation and personalized student performance analysis.
1. Admin Panel Features:
Live Class Broadcasting: Integration of a reliable and low-cost live streaming SDK (like Agora or 100ms) for conducting live interactive classes.
Content Management: Upload and manage recorded videos, study materials, and PDFs.
AI Test Generator: An interface where I upload a text file or PDF, and the system uses an LLM API (Google Gemini 1.5 Flash or OpenAI GPT-4o-mini) to automatically parse the content and generate a complete Test Series (MCQs with options and correct answers).
Dashboard: Overview of student enrollment, active users, and global performance metrics.
2. Student App Features:
Authentication: Secure login/signup.
Live & Recorded Classes: Video player to watch live streams and access VOD (Video on Demand).
Study Material Section: Access to attached PDFs and notes.
Test Portal: Interface to attempt the AI-generated test series.
3. AI Student Analysis & Reporting:
After a student submits a test, the app must send their answers to the AI API.
The AI should analyze the results and generate a "Personalized Summary Report".
The report must specify exactly which chapter and which specific topic the student is weak in, based on the questions they answered incorrectly.
4. Recommended Tech Stack (for Low Cost & High Scalability):
Frontend: Flutter or React Native (for a single codebase for Android & iOS).
Backend: Node.js with Express OR Firebase/Supabase (for rapid, low-cost backend development).
Database: PostgreSQL or MongoDB.
AI Integration: Google Gemini API (preferred for large PDF contexts) or OpenAI API.
Video Streaming: Agora.io or 100ms
