I'm making an AI-based assistant for mac (*cough*siriknockoff*cough*), and I want to add as many features as possible. So far, it can tell you the time and/or date, remember your name, play songs in iTunes, and open applications. I can't think of much else to add. Since obviously I can't connect it to Wolfram Alpha, it will never be able to do half of what Siri does, but I want it to at least be worth downloading. So basically, if you were to download this, what features would you want it to have (things you can ask it about or tell it to do)?
