Comments, mentions, and files

Keep the conversation and the files for a task in one place, so nobody has to dig through chat or email.

Comment and mention

Open a task and type in Write a comment… at the bottom. Markdown works: bold, lists, code, and links.
Type @ and a name to mention someone. The list only shows people who can see the board.
Click Comment, or press ⌘Enter.

People you mention get a notification. React to a comment with Agree, Great, or Seen, and edit or delete your own comments from their buttons.

Attach files

Drop files onto the task, or click Choose files under Attachments.
You can also paste a screenshot straight into the comment box to attach it.
Click a file to preview it. Images, PDFs, video, and text files get a preview; for other types, use Download.

For an image, choose Use as card cover to show it on the card.

Pin feedback on an image

Open an image attachment.
Click Add pin, then click the spot on the image.
Write your note in Feedback on this spot and click Post pin.

The pin is numbered on the image and posted as a comment. Click Resolve when it's handled. Resolved pins are hidden unless you turn on Show resolved.

Good to know

Each file can be up to 50 MB.
Commenting on a task makes you a follower, so you hear about later comments. See Notification settings and the daily digest.
Deleting a comment removes it for everyone.
