Student data should stay yours. Conversations that touch applications, grades, or accounts belong inside the systems your institution already manages, not in an external chat service.
Budgets favor owning it. A one-time license lets you put chat across admissions, IT, and student services without a per-seat cost that grows every term.
Coverage beyond office hours. Connect the chatbot API to answer routine questions overnight and during breaks, and captures the rest so staff can follow up when they are back.
