If there was something similar for adding video remarks to Google Docs, on Sunday night I got an email from somebody who had seen my videos about Mote and wondered. Among my suggestions was to attempt the e-Comments Chrome extension which
I examined last spring. Another alternative is to use a combination of
Screencastify and Google Keep to develop a bank of video comments that you can place into the comments of Google Documents or Google Slides..

The procedure of using Screencastify and Google Keep to create a video comment bank for Google Docs is fairly straight-forward. Record your brief video comments or short lesson with Screencastify. Second, get the “share” link from Screencastify. Third, create a note in Google Keep that consists of the link to the video (I recommend providing the notes easy-to-remember names and labels). Lastly, whenever you require the video link simply open Google Keep in the sidebar of the Google Doc youre viewing and copy the video link from the Google Keep into your remark..
