Use a canvas in Slack
When you need to share information that won’t fit in a simple message (like project plans or meeting notes), create a canvas. A canvas is a surface where you can create and share fully-formatted content with your coworkers, directly in Slack.
What to expect
There are two ways to use canvases in Slack:
-
Channel and direct message canvases
Every channel and direct message (DM) has a built-in canvas where you can store relevant and persistent details about the conversation and the work happening there. Channel canvases can be seen by anyone with access to the channel, and DM canvases are only visible to the members of the DM.
-
Standalone canvases
You can create a canvas for anything you’re working on — meeting notes, project briefs, or checklists — then share it with your coworkers in any conversation. You can also keep canvases private, for select eyes only.
Tip: Not sure what to use a canvas for? Check out our ideas and templates for canvas to get started.

A canvas in a conversation

Channel and DM canvases can be used to organize the information your team needs regularly, or for any important details someone in the conversation might need at a glance.

Tip: When the canvas in a conversation has content in it, the icon will change from the blank add channel canvas icon to the filled canvas icon.
