Ultra Hal Assistant is a chatterbot intended to function as a personal assistant. It was developed by Zabaware, Inc. Ultra Hal uses a natural language interface with animated characters using speech synthesis. Users can communicate with the chatterbot via typing or via a speech recognition engine. It utilizes the WordNet lexical dictionary. Its name is an allusion to HAL 9000, the artificial intelligence from the movie 2001: A Space Odyssey.
Ultra Hal won the 2007 Loebner Prize for "most human" chatterbot.
