For a free word processor, it’s hard to get much better than Google Docs. You can write an article (like this one), create your résumé, work on a paper, etc. right in your Google document. 

But if you’re an advanced user, the built-in features in Google Docs may not be enough for you. Having said that, you can add features to fill in the gaps and continue using it without any issues—with the help of Google Docs Add-Ons.

What is a Google Docs add-on?

It is a feature that adds new functionality to Google Docs that it previously lacked. The purpose of an add-on is similar to that of a browser extension—to gain additional features. 

Before we jump on to the list of best add ons, let’s have a look at how to install or remove an add on.

You can find all the Google Docs add-ons in the G Suite Marketplace.

How to install an add-on in Google Docs?

To install an add-on:

  1. In the Google Docs’ menu bar, click ‘Add-ons’ and then select ‘Get add-ons’. This opens the ‘G Suite Marketplace’.
  2. When you find an add-on you need, click the blue ‘Install’ button. The add-on will be installed in your Google document.
