I am looking for a program for google drive (or for a PC, perhaps a word plugin or something like grammarly), so that I can highlight chinese text and have a bubble show up with a dictionary translation. This would be great for Chinese learning, and I'm not even sure if such a plugin for an android app with dictionary plugin exists. Thanks.
Try converting the document to HTML, load it in Firefox or Chrome and use PeraPera Chinese (for Firefox, for Chrome). I haven't used Word for a long time, but I do remember it has an option to quick review a .doc or .docx as HTML, or similar. If not, just export it as HTML, and you can use Perapera in your browser displaying the document.
