Leave feedback with comments

Comment on the canvas or on an item

Comments are pins you place on the canvas. A comment can sit on an empty spot, on an item (video, image, PDF, board, and so on), or on an area you draw. Everyone in the room sees new comments right away.

1. Click Comment in the toolbar (next to Select and Laser), or press K.
2. Choose where the comment goes:
   • Click an item to attach the comment to it. The pin moves with the item when the item is moved or resized.
   • Click an empty spot to leave a free comment on the canvas.
   • Click and drag to mark an area. A dashed rectangle shows the area while the comment is open, and the pin sits at its bottom-right corner.
3. Type your comment in the box (Leave a comment. Use @ to mention.).
4. Press Enter or click Send. Use Shift+Enter for a new line.

After you post, the box turns into the comment card and the pin shows your avatar. The tool switches back to Select.

Add more to a comment

The buttons under the text box, from left to right:

• AI voice: record a voice note. Recording starts right away; click the pulsing button to stop. Your words are transcribed into the comment text and the recording is attached so others can play it. If transcription is not available, the recording is attached as audio only.
• Mention: tag someone in the room (you can also type @). See Reply, mention, and resolve comments.
• Attach: add images, videos, or PDFs as references. You can pick several files at once.
• Emoji: insert emoji. The picker stays open so you can add several.
• Annotation: draw on the canvas or the item with a pen. Pick a color and line thickness, or Clear to start over. The drawing shows only while the comment is open.
• Flag: tag the comment with a priority such as Urgent, High, Normal, or Low, or create your own with + Create new flag.

Comment text supports Markdown, for example bold, italic, lists, and links.

Close or cancel

• Press Esc to close the comment box.

Who can comment

• The room owner and people with the Can edit or Can review role can add comments.

• If the server refuses a comment you see Only reviewers and editors can add comments. Ask the room owner to change your role.

Good to know

• If you delete an item, the comments attached to it are deleted too (undo restores both).
• Comments do not appear when you export the canvas as an image.
• AI tools can add comments on your behalf: the in-app AI assistant, the Pactto MCP server, and the Pactto CLI with a write key.
