SimSimi wants to become your new virtual friend. He's a robot that looks like a yellow balloon that you can talk to and tell him about your daily worries. He might not be able to do so many useful things as Siri or Cortana, but at least he gives you somebody to speak to and a way of spending your free time.
A conversational bot with a great artificial intelligence.
By downloading the APK of SimSimi to your Android smartphone or tablet you'll have an application that resembles an online chat or instant messaging service, but instead of talking to a friend, you'll be chatting with the app's artificial intelligence, with whom you can talk about almost anything, but you'll have to be careful about using swear words.
Who's SimSimi? Is he a real person?
No, he isn't. Although his answers are tremendously realistic, you won't be speaking to a real-life person, but a kind of bot. So you don't have to worry about the things you tell him or the questions you ask him because the application is totally secure and SimSimi won't go running off tell anyone your secrets.
The more you talk to him, the smarter he'll become and the more realistic the conversation will be, because he's capable of learning from whatever you talk to him about. He'll soon learn how to answer to certain statements and behave when confronted with certain situations. Furthermore, he's got a rather peculiar sense of humor, so your conversations are going to be really funny.
