Bored with nobody to text? Take a look at CleverBot Chat.
CleverBot Chat is a novelty chat app that allows you to chat with the online Cleverbot AI (but was not developed by Cleverbot). Conversations can be about anything you want but beware the conversation may take on a life of its own.
Interface is your typical SMS messaging screen with text boxes for your's and CleverBot's messages. In just tinkering with CleverBot Chat, I've had conversations about religion, football, what's the best smartphone (CleverBot says the iPhone) and what I should cook for dinner (chicken). Every now and then CleverBot would get a little grumpy, insulting or change the topic completely.
Once you exit the app, the conversation is deleted. For the most part, CleverBot Chat ran smoothly but I did receive a few "Failure to Send" errors on messages. Nothing to pull your hair out over but noticeable.
If you're looking for an interesting novelty app, CleverBot Chat is worth a try. CleverBot Chat is a free, ad-supported app the you can download here at the Windows Phone Marketplace.
