Sometimes it feels like the world could do with a real-life version of Halo’s Master Chief, but for now the closest we’re going to get is Cortana. Named after and voiced by John-117’s ever-present AI helper from the multi-millionselling Xbox games, Cortana is Windows Phone’s answer to Siri or Google Now – with a little extra added on top. As well as simple web searches and most standard phone
functions, Cortana can attach reminders to other actions, so next time you go to phone your mum Cortana will nudge you to politely ask about the cat. Over time she’ll learn more about you, adding details to a ‘notebook’ full of your vitals that she’ll use to offer more targeted help. With the Xbox One and Windows 8 (or 9) the obvious next steps for Cortana, expect to hear her voice a lot more in the future.
