Other features include an ability to stay on subject during a conversation, and an enhanced system for answering questions and learning facts. The current version of Billy also introduces the concept of mind files which contain his knowledge, language, and personality. These can be easily transferred to other users of Billy via the internet or disk. Daisy, however, has no pre-programmed language of any kind. While Billy contains many responses, which are programmed to be said if the user types in certain sequences of words.
Daisy contains no built-in responses.
She starts with no knowledge of anything, but then is able to gain knowledge as she observes what humans say. It can take a little while before Daisy has gained enough knowledge to be able to create her own sentences. To get you started, the Daisy distribution file contains one memory file, which was built by having Daisy talk to me. However, you are always able to create a new file and start from scratch.
