Virtual assistant Cortana holds people to promises

Microsoft virtual assistant Cortana began holding people to their promises on Thursday. "Now, Cortana can help you remember things you've said you would do in your emails -- without you even having to ask," partner group program manager Marcus Ash said in a blog post. "Cortana automatically recognizes when you make a commitment in email messages and will proactively suggest a reminder to you to follow through at just the right time." An update to Cortana -- Microsoft's digital assistant infused with artificial intelligence -- enables it to recognize and make note when people promise in messages to tend to tasks, according to Ash. "We've all been in the situation where we've promised to do something in email, like send your boss a report by end of day, or purchase tickets to the movies for your date night," Ash said. "But the day goes on, emails pile up, and you quickly forget. Now Cortana has your back."
