Chat bots have been present since late 90s. The first ever, Cleverbot has paved way for many that have come in years after. One of the most praised and used robot chat bot is Mitsuku. It was created from AIML technology by Steve Worswick. Mitsuku is three times Loebner Prize winner. This award is given to the most human like Chat bot and Mitsuku won in in 2013, 2016 and 2017, and also was runner-up in 2015. This AI chat bot is available as a flash game on Mousebreaker Games and on Kik Messenger under the username "Pandorabots". For certain time it was also available on Skype under the same name, but it got removed by its developers. It is estimated that this robot chat has conversed with millions of people worldwide via both the web and other applications. On average, Mitsuku on Kik Messenger converses quarter million times daily.
Mitsuku says to be an 18-year-old female chat bot from Leeds. It has all of Alice’s (natural language processing chat bot) AIML files and additional files from user generated conversations. Steve Worswick claims that it has been work in progress since 2005. Intelligence of Mitsuku include the ability to reason with specific objects. It has database with properties connected for certain number of objects. For example, if asked if house can be eaten, it will go through database and look up the properties connected for house. It also features abilities to play games and do magic tricks at the user’s request.
Another three times Loebner Prize winner and source of many Mitsuku files is Alice (also know as A.L.I.C.E and Alicebot). It is a natural language processing chatbot, a program which engages in a conversation with a human. This AI chat bot applies some heuristically pattern matching rules to the human's input, and in its online form it also relies on a hidden third person. Even though it won Loebner Prize in 2000, 2001 and 2004, it still has not been able to pass the Turing test. Reason for that is that even the casual user will often expose its mechanistic aspects in short conversations. Original designer for Alice was Richard Wallace and it came to life in 1995, but the current version has base from 1998 which was rewritten in Java. Alice uses AIML (artificial intelligence markup language)for specifying the heuristic conversation rules and it has been reported that its code is available as open source. Alice has been cited as the inspiration for academy award-winning film Her by Spike Jonze in which human falls in love with a chat bot.
Another honorable mention of Loebner Prize winners is Ultra Hal Assistant. This AI chat bot is set to function as a personal assistant. Loebner Prize was won in 2007. Name of the assistant comes from an allusion to HAL 9000, the artificial intelligence from the movie 2001: A Space Odyssey. Ultra Hal also uses a natural language interface but with animated characters using speech synthesis. Users communicated with robot chat via typing or via speech recognition engine.
