On Sunday night I got an email from someone who had actually seen my videos about Mote and wondered if there was something comparable for including video comments to Google Docs. One of my recommendations was to try the e-Comments Chrome extension which
I evaluated last spring. Another alternative is to use a combination of
Screencastify and Google Keep to build a bank of video comments that you can insert into the remarks of Google Documents or Google Slides..

The process of using Screencastify and Google Keep to produce a video remark bank for Google Docs is fairly straight-forward. Third, produce a note in Google Keep that contains the link to the video (I recommend giving the notes easy-to-remember names and labels).
In this video I demonstrate how to use Screencastify and Google Keep to produce a bank of video remarks that you can place into the comments of your trainees Google Docs and Slides..
