Cleverbot

Cleverbot is an AI web application that learns how to mimic human conversations by conversing with humans. It was created by AI veteran Rollo Carpenter who also created a similar web application called Jabberwacky. Cleverbot differs from traditional chatterbots in that the user is not holding a conversation with a bot that directly responds to entered text. Instead, when the user enters text, the algorithm selects previously entered phrases from its database of 20 million conversations. It has been claimed that, "talking to Cleverbot is a little like talking with the collective community of the internet."
