It’s currently working fine inside of Google Docs.
However, it’s very typical when two or more people are collaborating on a Google Docs document for one person to select a word add a comment about it in the right sidebar.
When you select any word inside of a Google Document, asmall plus sign appears on the right edge of the document and when you click that it opens the box where you to make your comments about this word or this section of the document.
I noticed that LipSurf does not work in these boxes and I have to revert to manual typing.
