Microsoft is now rolling out Cortana inside of Skype

Microsoft is starting to roll out Cortana inside of Skype, letting its smart assistant jump into

private and group chats to offer assistance in making plans and looking up information. Cortana will be available on both iOS and Android, but Microsoft says its assistant “will be gradually rolled out” starting in the US, so you might not have access yet.                                                               https://www.theverge.com/2017/10/10/16452326/cortana-skype-integration-launches
