ChatBot only within a website
I have a client who would like to gather all their material for a specific industry and give their members access to all the material via ChatGPT. They want an XXXGPT β but I'm not sure that's the right way to go. For example, all their members must have the paid version of ChatGPT to use this GPT. I have suggested that they gather all their material on one website and then get a Chatbot that only answers questions, within that website and does NOT include information from the rest of the web or its own repository. Am I on the right track? How do I best and most securely set up such a Chatbot?
