"It's a bit of a head scratcher for us right now," Windows Phone Group Program Manager Marcus Ash said at the SMX Advanced Search Marketing expo on June 12.
If nothing else, his comment indicates that Cortana's expansion to other platforms is an ongoing conversation at Microsoft.
Home sweet home
In addition to Ash's quotes, statements made by Applications and Services Group Program Manager Rob Chambers were also referenced by Search Engine Land.
According to the site, Ash said they're "actively talking about" Cortana on iOS and Android, and the duo even reportedly went further than that, discussing Cortana on desktop PCs, Cortana in vehicles, and more.
There are hurdles in that iOS and Android users might not want Cortana, as they already have Siri and Google Now, respectively.
And Cortana might not have access to many of the features on those platforms, including users' personal data, that it uses on Windows Phone.
