Introduction

This paper presents ContXpert, an AI-powered WhatsApp chatbot designed to improve student support services in educational institutions. Traditional academic portals often require repeated logins, are not always mobile-friendly, and increase administrative workload due to repetitive student queries. Since WhatsApp is widely used by students, the proposed system provides a convenient conversational interface for accessing academic and administrative information.

ContXpert integrates WhatsApp Cloud API, Large Language Models (LLMs), Natural Language Processing (NLP), Retrieval-Augmented Generation (RAG), and institutional databases to deliver instant, personalized, and 24/7 support. Students can securely authenticate using their USN and mobile number to access attendance records, marks, notifications, certificate requests, fee status, and other services directly through WhatsApp.

The literature review shows that AI chatbots improve communication, reduce response time, increase student engagement, and lower administrative workload. However, existing systems generally focus on FAQ handling or limited academic support and lack deep integration with institutional databases, secure authentication, workflow automation, and WhatsApp-based communication.

To address these gaps, ContXpert offers a unified platform with features such as:

• Secure USN-based authentication
• Real-time attendance and marks retrieval
• Attendance shortage alerts
• CIE aggregation
• Notification management
• Certificate request and payment tracking
• Multi-department support

The system uses a modern technology stack including Python, Node.js/Flask, MySQL/MongoDB, LangChain, FAISS/ChromaDB, WhatsApp Cloud API, and cloud platforms such as AWS, Render, or Railway. Its modular architecture consists of communication, NLP processing, backend services, database management, notifications, and payment integration modules.

The proposed dataset includes student records, attendance, assessment marks, fee status, notifications, and certificate request information, supporting deployment for more than 10,000 students across multiple departments and semesters.

Conclusion

ContXpert, is an AI-powered WhatsApp chatbot designed for intelligent student support systems in educational insti-tutions. The proposed system integrates conversational AI, WhatsAppCloudAPI,NLP,Retrieval-AugmentedGeneration (RAG), and institutional databases to provide real-time aca-demic and administrative assistance. The literature survey and comparative analysis demon-stratethatexistingeducationalchatbotsystemsmainlyfo-cus on general query handling and lack unified integration with institutional workflows. The proposed system addresses these research gaps through secure authentication, attendance monitoring, automated alerts, certificate request tracking, and personalizedstudentinteractionwithinasingleconversational platform. The proposed architecture is scalable, user-friendly, and capable of reducing administrative workload while improving accessibility for students. Although implementation is cur-rently under development, the framework establishes a strong foundation for smart educational support systems.
