Hi.

Do you know simisimi? (simisimi.com) is smart reply chat bot learning word from people

so, I had the idea to make a bot like simisimi, for example:
if someone type "*hi*" and bot will random reply "hi to", "hello buddy", "long time no see"

and someone can add database with command !addreply (keyword):(reply) example:
!addreply *hi*:im here
!addreply *hi*:whats up buddy

and someone can add more chat database reply
!addreply *facebook*:sorry im not have facebook account
!addreply *facebook*:what is your facebook account?
!addreply *operator*:operator channel not online right now
!addreply *operator*:whats the problem?
!addreply bot:you are robot, im not
!addreply bot:oh yeah?

so, anybody can make that script?
