From Boray Software:
Do you want to play a joke on your friends?
Or perhaps you are tired of some attention demanding chatter and want to do something else for a while? Crazy Chat Robot is the program you can let chat in your place. It's your crazy chat stand-in.
You can use it with any chat program or your can just chat with the robot yourself if you like.
Crazy Chat Robot is highly configurable. You can for example write your own chat lines or extract them from a chat log.
The built in dialog is free from swearing and from sexual content.
Also available in Swedish.
