An @ Comment in Google Docs Can Assign a Task

A shared document full of comments like "this could use some detail" has one flaw: nobody specific is responsible for anything, so the notes hang around for weeks. Docs, Sheets, and Slides can actually turn a comment into a real task: mention a colleague with an @, check Assign — and that person gets a notification, the task counts against them, and they're the one who can resolve it. A vague "someone should" becomes a pointed "you will."

How to do it

1. Select the text (or cell, or object) the comment concerns and insert a comment — via the button, or the shortcut Ctrl + Alt + M.
2. In the comment text, type @ and start typing your colleague's name or email; pick them from the suggestions.
3. A checkbox labeled Assign to… appears below the comment — check it and send.
4. The colleague gets an email notification with an excerpt and a link straight to the spot in the document. The comment visibly shows who it's assigned to.
5. Once it's done, the assignee clicks the Mark as resolved checkmark — the thread tucks itself away but stays findable in the comment history (the comment icon top right), so you can return to it anytime.
6. A task can be reassigned in a reply too — responsibility passes along, nothing falls through the cracks.

Two extra nuances: you can mention someone who doesn't have access to the document yet — Docs will offer to share it with them right away, including the access level. And anyone getting too many notifications can dial them back: the bell icon in the comments panel lets you subscribe only to comments that concern you directly.

A typical scenario

A marketing lead reviews a press-release draft. Instead of an email listing "Jane, add the quote; Peter, verify the numbers," she goes through the document and leaves an assigned comment right at each spot for whoever needs to fix it. Jane and Peter each get a notification linking straight to their sentence, and check off the task once it's fixed — and the lead can see in one place what's done and what's still hanging. No digging through email threads.

What you get out of it

Comments with an owner and a status: at a glance you can see who has to do what and what's already resolved. A whole layer of coordination emails — "did you already fix that?" — disappears, because the document runs its own review cycle. And because resolved threads stay in the history, even the reasoning behind a change is never lost.

Pro tip

The @ in comments is a sibling of @ inside the document text itself — in the body it inserts mentions and templates, in a comment it delegates. Together they make Google Docs a full-featured team review tool.
