Here is my Facebook Artificial Intelligent Chat bot plugin, I developed it, almost 1 year back..It should work properly if Facebook did not make any significant changes in there chat UI(element , class names etc)
Was planning to add an UI to it, But still not completely done.. :( :(
Actual intelligent bot is hosted in Google app engine, So this plugin bypasses Facebook's content security policy by striping few response headers, to communicate with app engine server. So use at your own risk.
Instead of using intelligent chat bot server, you can also configure custom reply to your friends. although i haven't tested this much.
Example given below
