According to Microsoft, “Today, we’re starting to roll out new capabilities to Word that help users create and fill in these placeholders without leaving the flow of their work. For example, type TODO: finish this section or <<insert closing here>> and Word recognizes and tracks them as to-dos. When you come back to the document, you’ll see a list of your remaining to-dos, and you can click each one to navigate back to the right spot.”
Microsoft also adds that its AI system can learn and adapt to your needs. “Over time, Office will use AI to help fill in many of these placeholders. In the next few months, Word will use Microsoft Search to suggest content for a to-do like <<insert chart of quarterly sales figures>>. You will be able to pick from the results and insert content from another document with a single click.”
Interestingly enough these AI features are actually coming to Word on Mac for Office Insiders first, but it is expected to eventually expand to Office 365 subscribers across all platforms.
