This is really nice, thanks for sharing.
I have a small question, I found this AI Chatbot randomly, it is an AI powered GPT enabled chatbot which is an AI shopping assistant for ecommerce brands.

Do you know about this, if yes how it is different from your chatbot?

Thank you, both actually use for same purpose. But this amazon lex chatbot AI enable you to query from endless use cases. If you are using aws for your application go for amazon lex and aws lambda.
Just see aws lex customer success story for better understanding.
