Commenting

The commenting feature in Overleaf makes it easy to review and discuss your LaTeX documents directly within the editor.

The basics

Comments in Overleaf allow users to add comments tied to specific lines of code in the editor. These comments appear in a sidebar and can be viewed, replied to, and resolved by all collaborators with access to the project.

Accessing the comment feature

Highlight some text within the editor to comment on, once you have done so the 'Add comment' button appears. Select it and the review panel will open on the left hand side, there you can type your comment.

Using comments

Once you or your collaborators have created a comment, you can resolve the comment by clicking on the checkmark ✓ attached to the comment. If you are looking to edit or delete your comment select the ellipsis menu , and select 'Edit' or 'Delete'.

You may also access the list of resolved comments in your project by clicking on the resolved comments icon () within the review panel.

While viewing the resolved comments you are also able to delete the thread of comments by clicking on the trash icon (), or re-open previously resolved comments by clicking on the 'Re-open' icon ()

Collaborative commenting

Collaborative commenting in Overleaf provides a streamlined way for teams to review and discuss a LaTeX document without making direct, permanent edits. This feature facilitates targeted feedback, allows collaborators to reply and resolve discussion threads, and ensures all project members can see, track, and manage input efficiently, keeping the document clean while collaboration is active.

Mentions

Flag something for a specific collaborator by mentioning them directly in a comment. Type @ and start typing their name (or email address) to prompt a list of collaborators.

Notifications

Email notifications on project activity must be enabled in your Account Settings.

You can manage notification emails per project through the Project Settings (File > Settings > Project Notifications) for the following types of activity:

• All project activity - You’ll be notified about all comments (and tracked changes).
• Mentions and replies only - You'll be notified about mentions, replies, and activity on your comments and tracked changes.

Notifications are not real-time, instead they are bundled in ten minute increments to avoid inbox overload.
