What are some really good chat bot platforms that you have come across?
I am in the process of building a conversational mobile app to make bookings of some sort. I have evaluated Dialogflow to an extent. I know about wit AI and Watson assistant although I haven't used them. I am looking for the best possible platform in terms of cost, accuracy and features. Would also help if you could share some good chat bot mobile apps you have come across. I found Niki AI pretty interesting.
