I haven’t used it but I’m pretty sure that HN readers tend to appreciate if you had provided a privacy policy and a terms of service.

Otherwise, at the minimum, make it clear in your FAQ.

Some questions that I have floating around:

- Who’s processing my data? OpenAI? A service from AWS? Bare metal with your own solution?

- What are the limitations? Would a 1 hour lecture video off YouTube work?

Slight nitpick: You’ve got a domain name, why don’t you use that as your contact email? It would be nicer, in my eyes, to have something like “<your first name>@hichatbot.ai” instead of “hichatbotai@gmail.com”.
