EduReach Platform

EduReach is a modern, feature-rich educational platform designed to showcase college life, courses, and placement records while providing an interactive and intelligent user experience. It employs a smart scroll-gated content strategy to encourage student sign-ups and features an advanced AI-powered counselor specifically trained on the college's knowledge base.

Features

• Dynamic Landing Page: A beautifully designed homepage featuring Hero, About, Courses, Mentors, and Achievements sections.
• Gated Content Strategy: Engages users by showing initial content publicly, then seamlessly prompting them to sign up to unlock premium sections like Student Life, Events Gallery, and Hiring Statistics.
• AI-Powered Counselor (RAG Chatbot): Includes a floating chat widget powered by Google Gemini and LangChain. It uses Retrieval-Augmented Generation (RAG) backed by MongoDB Atlas Vector Search to provide precise answers about courses, fees, admissions, and campus life based on a custom knowledge base.
• Secure Authentication: Robust user authentication system using JWT (JSON Web Tokens) and bcrypt for password hashing.
• Modern Tech Stack: Built with React 19, Vite, Tailwind CSS v4 on the frontend, and Node.js with Express and TypeScript on the backend.

Uniqueness of the Project

1. Context-Aware AI Assistant: Unlike generic chatbots, the AI Counselor is implemented using LangChain tools and MongoDB Vector Search. It retrieves specific information from an internal knowledge base (edureach-knowledge.txt), ensuring that answers are highly relevant to EduReach College.
2. Smart Conversion Journey: The platform uniquely blends a marketing landing page with a web app by using scroll-triggered events to display call-to-action popups (Sign Up/Call) right as the user hits the "Mentors" section, maximizing lead generation.
3. Full-Stack AI Integration: Demonstrates a complete, end-to-end integration of modern AI practices (Embeddings, Vector Stores, LLM Agents) within a standard MERN-like stack.
