Chattbot for Students

As a college student, I’m looking for a website chatbot that we can use it on our own website not on the collage website or any website which can help answer our questions as quickly as possible. The chatbot’s primary purpose would be to provide answers to our FAQs, by finding real information from our college website or a database. It is look like chatgpt but in small size.
For example , if any students open the website chatbot and ask any question related to our study or any news , it will answer by real information take it from the collage website or seperate pdf files.
I’m open to any designs or interfaces that would best enable this function, so I am looking for the most innovative solution.
