I need chat bot api

Create knowledge base, from pdf files for example, to build a custom GPT, specialized in a particular domain.

Hello, I wanted to know if you have or are planning to implement on your website the possibility of creating a personalized bot to which I can upload my own content. I am an economics teacher and I would like my students to have access to that bot available on my subject's website so that they can ask specific questions about my subject. Waiting for your response, receive a cordial greeting.
