AI-Powered Travel Planning Portal

The Student Travel LLM App is an innovative AI- powered platform that revolutionizes accommodation management and travel assistance for foreign and domestic students. Leveraging Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), and vector database technologies, the system provides personalized housing recommendations, automates Pre-Travel Clearance (PTC) processing, and delivers intelligent access to government schemes and institutional policies. The platform integrates a microservices-based architecture with a conversational AI interface, offering semantic search capabilities through vector embeddings stored in Chroma database. By combining advanced natural language processing with geospatial data analysis using PostGIS, the system enhances decision-making efficiency by 30-40% while ensuring transparency and inclusivity in academic mobility. Evaluation results demonstrate significant improvements in accommodation search accuracy (80.8% precision), reduced processing time (from days to minutes), and enhanced user satisfaction through personalized, policy-grounded recommendations. This intelligent solution addresses critical challenges in student travel planning by unifying fragmented information sources, automating administrative workflows, and providing contextually relevant guidance based on individual preferences and institutional requirements.
