A big thanks to Nicholas Walker for introducing me to the subject of virtual characters and chatbots. Cleverbot is one clever robot. But try convincing Cleverbot that he is a robot and you might be facing a stiff fight, er.. I mean conversation.
Launched on the Web in 1997. 65 million conversations since then. Judged to be 59.3% human in the 2011 Turing Test, far exceeding AI experts' expectations, as the humans in the same event "achieved just 63.3%" (Wikipedia). Cleverbot is one impressive piece of software.
Available on the Web with text synthesis and voice recognition, Cleverbot has been mimicking human conversations with uncanny accuracy for more than a decade. Cleverbot is also available on iOS and Android (with a spoken voice!).
