Yes! The POP Chrome Extension works in Google Docs.
When using the POP Chrome Extension you can get your recommendations right where you are editing. Additionally, your Optimization Score will update in real time in the Extension and checking your score or important term counts in the Extension does not count as a report credit in POP. You can check your scores or counts an unlimited amount of times in the Extension.
You can learn more about the extension in the video below. As well as in our chrome extension guide here.
