Microsoft is working on a new Microsoft Word feature for Office users on Windows Desktop.
The Smart save feature is available to Beta Channel users who are using Version 2006 Build 13001.10000 or later.
With the help of machine learning, Microsoft Word will intelligently prompt users to save unsaved documents and avoid losing work.
Word uses machine learning to understand how likely you are to save a particular file. Using various attributes, such as how much time you’ve spent working on the file or how much content you’ve added to it, Word will remind you to save. These reminders will help you reduce the risk of losing your content if you haven’t saved the file yet.Smart save reminders in Microsoft Word
