Comments
A comment anchors to whatever it is about — a card, a group, an empty point on the canvas, the board as a whole, or a range of text inside a document. Comments thread, resolve, and support @ mentions that notify the person named. An eye toggle hides all of them when you want to see the board clean.
Comments attach to the thing they are about. This is the whole design: feedback that lives in a sidebar, ordered by time, loses the connection to what it referred to within a day.
What you can comment on
| Anchor | Reads as |
|---|---|
| A card | "this image" |
| A group | "this sequence" |
| An empty point | "something should go here" |
| The board | "the whole thing" |
| A text range in a document | "this sentence" |

Threads
Comments thread with replies. Resolve when the thing is dealt with — resolved comments are archived rather than deleted, so the record of why something changed survives.
Mentions
Type @ in a comment to mention someone. They are notified. See Notifications.
You can also mention clusters, documents and cards, which turns a comment into a navigable link rather than a description of where to look.
Hiding them
The eye toggle hides every comment bubble on the board — for you only, not for everyone. Use it when presenting or when the feedback has piled up and you want to see the work.
Bubbles on a crowded board
Comment bubbles lay themselves out to avoid covering the content they refer to and to avoid stacking on each other, so a heavily-reviewed board stays readable.
Who can comment
Editors can. Viewers cannot — a viewer can read the board and vote, but leaving comments requires edit access. If you want feedback from someone, invite them as an editor; it costs nothing on any plan. See Collaborating.
Comments versus votes
- A comment is a sentence: reasoning, a request, a decision, with a thread and a record.
- A vote is a count: which of these, quickly, with no discussion.

Frequently asked questions
Can I comment on empty canvas?
Yes. A comment can anchor to a point rather than an object, which is how you leave "something should go here".
How do I hide comments for a presentation?
The eye toggle hides every comment bubble on the board. It affects only your view.
Do resolved comments disappear?
They are archived rather than deleted, so the record of a decision survives.
