Available for

  • Beginner
  • Pro
  • Business

Take back time spent hunting for the information you need to get stuff done. With task and project comments you can add notes, upload any file, and even discuss details with your coworkers. Everything stays neatly organized right inside your tasks and projects so you can get right to work.

Add comments and files to tasks


Comments are always listed chronologically. You can't manually change their order.

  1. Hover over a task and click the speech bubble icon that appears to the right of the task name.
  2. Type a comment into the comment field.
  3. Click any of the following:
    • Paperclip icon: attach a file. See all the supported file types.
    • Microphone icon: record an audio comment.
    • Emoji icon: add an emoji.
  4. Tag someone to notify them about your comment, if needed.
  5. Click Comment to save it.

Add comments and files to projects

Project comments are attached to the whole project rather than a single task. They keep any high-level project information or files organized and in one place. If you're working in shared projects, project comments are handy for keeping everyone on the same page. 

  1. Click the project in the sidebar.
  2. Click the comment icon at the top-right.
  3. Enter your comment or click the paper clip icon to attach a file.
  4. Click Comment to save it.

Notify someone about a comment

There will be times when you write a comment and want to make sure your teammate sees it. In those cases, you can notify them.


To notify someone about a comment in a personal project, you’ll need to share the project with them first. To notify someone in a team project, make sure the person is part of your team.

If you would like to tag someone in your comment, here's how:
  1. Start a new task comment or project comment in a shared project.
  2. If you would like to tag the other person directly:
    • Enter @ in the comment field and start typing out their name.
    • You will see a list of names matching what you're typing. Once you see the person you want to tag, click their name.
  3. If you would simply like to notify them without tagging them directly, do the following:
    • Click the field next to Notify.
    • Select the users you’d like to notify by clicking their names (or click Everyone if you wish to notify everyone in the project).
  4. When you post the comment, the selected people will receive the comment in their notifications.

Delete a comment or file


You can only delete your comments in a task. If you need to remove someone else's comments, ask the author to delete them. If the author is no longer a member of the project, duplicate the task to remove all comments.

Delete a comment

  1. Click a task to open the task view.
  2. Find your comment in the Comments section.
  3. Click the three dots icon to the right.
  4. Select Delete.

Delete a file

  1. Click a task to open the task view.
  2. Find your file attachment in the Comments section.
  3. Click the three dots icon to the right.
  4. Select Edit.
  5. Click Delete beside the file name.
  6. Click Update to save the changes.
