SIT Directory is a web app powered by a multi-agent RAG system and a curated knowledge base, delivering instant, accurate answers about SIT@KMUTT academics, facilities, regulations, and more. Students and visitors can get information via chat or optional voice, while staff manage documents and content in a secure admin panel. The app also includes an events carousel, a static campus map, and QR-linked documents. By giving quick, self-serve answers and clear navigation, it reduces student waiting time and frustration while also cutting the manual workload for staff.
