I need a web based chatbot. i need super admin where I will create a user. i will give the user user ID and password. user will add keyword and associated message to that keyword. so for eg if user adds a keyword HELLO and associated message let's he adds welcome to my shop. so when end user types HELLO that message should appear on chatbot page. page should look like a chatbot window. message me if anyone who is interested will discuss in detail.
