I would go with Ada for this because i really like that it’s focused on taking repetitive support questions off the customer support team’s plate rather than just being another generic chatbot on the support webpage but if I’m being practical I think the bigger test is what happens a few months into the launch. Does it stay accurate, how much work does it take to keep it updated and how often are customers still asking to speak to a human agent. All these are important questions I’d definitely want to know before making the final call.
