Cleverbot, The famous sign for AI (Artificial Intelligence).
Cleverbot is a programmed robot that us used to show people how great can AI be. You can access to their website and chat with the Robot. Actually in my first time, It was REALLY convincing. For me it was no way that robots can be so.. real. Before I post this link and to avoid Illegal Content. You must Understand that chatting with Cleverbot is at your own responsibility. He won't do anything, Just do not post links for porn. Or fake that your an Russian spy or something. Click here
to visit Cleverbot official website.
No matter how convincing it can be.. It is not real. It is programmed to learn from people chatting. So it will act as a human. Also.. It is convinced that It's a human being. The Bot will convince you that he's a human and your a metal. So don't get angry and turn your PC into junk.
