I don't know if many of you have heard of Siri for the iphone. Basically, it's a helper on your phone that you can talk to and it will obey you. You can say things like "set my alarm for 5:30", "Call Jane for me", "What's the weather going to be like" and so on.
Now imagine you were developing something similar. What name would you give to it? Somethng snappy that gives away what it does without being too cryptic.
