How to Add a Comment in Google Docs: A Step-by-Step Guide

posted on October 31, 2025

Adding a comment in Google Docs is a simple process. Just highlight the text you want to comment on, right-click, and select "Comment." Alternatively, you can use the shortcut Ctrl+Alt+M (Cmd+Option+M on Mac). Type your comment in the box that appears on the right and click "Comment" to post it. This allows you to provide feedback or suggestions without altering the original document.

After you add a comment, it will appear in the margin of the document, tagged with your name and the timestamp. Other collaborators can reply to your comment, creating a thread for discussion. You can also edit or delete your comments if needed.

Introduction

Google Docs has revolutionized the way we collaborate on documents. With its easy-to-use interface and real-time editing capabilities, it’s no wonder that so many people have made the switch from traditional word processors. One of the best features of Google Docs is the ability to add comments. This is incredibly useful for providing feedback, asking questions, or suggesting edits without making permanent changes to the text.

Whether you’re a student peer reviewing a classmate’s essay, a manager providing feedback on a report, or a writer working with an editor, comments are an essential part of the collaborative process. They allow for clear communication and can help improve the quality of the work. Plus, since Google Docs is cloud-based, you can add comments from anywhere, whether you’re at your desk or on the go with your mobile device. Let’s dive into how to take advantage of this nifty feature.

Step by Step Tutorial: Adding a Comment in Google Docs

Before we proceed with the steps, it’s worth noting that adding a comment in Google Docs will enable you and your collaborators to communicate directly within the document without altering any of its content.

Step 1: Select the Text

Click and drag your cursor over the text you wish to comment on.

Selecting the text ensures that your comment is associated with the specific part of the document you’re referring to. This helps to avoid any confusion and makes it clear which section or sentence you’re discussing.

Step 2: Right-Click and Select "Comment"

Right-click on the highlighted text and choose "Comment" from the context menu.

By selecting "Comment," a comment box will appear on the right side of your Google Doc, ready for you to type in your thoughts or feedback.

Step 3: Type Your Comment

Type your comment into the box that has appeared on the right side of the document.

Your comment can be as brief or as detailed as you like. Remember that others will be able to read and respond to what you write, so make it clear and concise.

Step 4: Post the Comment

After typing your comment, click the "Comment" button to post it.

Once you click "Comment," your note will be visible in the margin of the document. If anyone else is viewing the document, they’ll receive a notification that a new comment has been added.

Pros

Benefit Explanation
Improved Collaboration Adding comments in Google Docs makes teamwork more efficient and effective. Rather than sending back-and-forth emails with feedback, comments are in the context of the content being discussed. This immediacy and relevance streamline the revision process and enhance collaboration.
Non-Destructive Editing Comments allow for suggestions and feedback without altering the original text. This means that the integrity of the original document is maintained, and changes are only made after consideration and agreement.
Easy Tracking of Changes With the ability to reply to comments and mark as resolved, it’s simple to track which feedback has been addressed and what still needs attention. This organizational benefit ensures that no suggestion or critique gets overlooked.

Cons

Drawback Explanation
Potential Clutter If a document has too many comments, it can become cluttered and difficult to navigate. This can be particularly challenging when multiple people are commenting at the same time.
Overreliance on Comments There’s a risk of overusing comments for extensive edits that would be better made directly in the text. This can lead to a cumbersome revision process and confusion over what changes have been agreed upon.
Notification Overload Frequent comments can result in a barrage of notifications, especially if you’re tagged in many documents. This can be distracting and sometimes overwhelming, disrupting your workflow.

Additional Information

Adding a comment in Google Docs is just the tip of the iceberg when it comes to the collaboration features available. For instance, did you know you can also tag a specific person in a comment? By typing "@" followed by their email address, you can ensure they receive a direct notification about your comment. This can be particularly useful when you need to draw someone’s attention to a specific section or when assigning tasks.

Another tip is to use the comment feature to keep track of your own thoughts as you review a document. Instead of editing the text directly, you can leave a comment for yourself as a reminder to revisit a section or conduct further research. This way, you won’t disrupt your workflow, and you can easily find and address your notes later.

Remember, Google Docs comments are not just for critiques. They’re also great for leaving positive feedback and encouragement. A simple "Great job on this section!" can go a long way in a collaborative environment.

Summary

  1. Select the text related to your comment.
