It's not (necessarily) a chat bot. I worked at a company that used Intercom, there were actually customer support reps responding to inquiries. It was actually a nice platform for triaging inquiries and support requests. You could even have side-conversations among employees in it, e.g. when one of our models gave weird predictions they would tag me in the conversation so I could tell them how to respond to the customer.

That said, having your website break when it's not loaded is bad.

No, if you have cookies disabled it can't log on to the live demo. As mentioned before, it's not a chatbot, it is just a way for you to get in touch with us right out of the app without opening an email client. If we are around we will also answer in the chat directly.
