I'm trying to build a simple bot that answers questions based on various sources that I add to the knowledge base. While my knowledge base covers a lot of questions, it certainly doesn't cover all of them. Is there a way to use Chat GPT or something similar as a fallback? If so - I'd highly appreciate if you coud point me in the right direction. If that's not possible, I need to figure out a way for the bot to save the unanswered questions and ask for an email so I can contact the user and answer their open question.

You could implement a test to check if the KB found anything, and if it didn't you put a transition to an AITask passing something like "Answer the user's question" as the task instructions and the user's question as Task input

Thank you, that sounds like a great idea! Unfortunately, I can't set that up correctly. How do I store the users question in a variable correctly to send it to my AI task?

The main way to store user input is to use capture cards
