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. Canvases are a surface where you can create and share fully-formatted content with your coworkers, directly in Slack.
Note: Canvases are rolling out to all teams gradually. We appreciate your patience as we make them available to everyone.
What to expect
There are two ways to use canvases in Slack:
-
In a conversation
Add content to the canvas in a channel or direct message (DM). Every conversation has a built-in canvas where you can store relevant and persistent details about the conversation and the work happening there.
-
On its own
You can create a canvas for anything you’re working on — meeting notes, project briefs, or checklists — then share it with your coworkers in a 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.
Get started
A canvas in a conversation
A canvas on its own
Every channel and DM comes with its very own canvas. Canvases in conversations 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.
- Click the blank add channel canvas icon in any conversation header to open the canvas.
- If you have permission to post in the conversation, start typing to add content to the canvas.
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.
You can create a canvas on its own for anything you’re working on — from employee onboarding to company newsletters, project briefs and more.
Desktop
- From your desktop, click Canvases at the top of your left sidebar. If you don’t see this option, click More to find it.
- From the Canvases view, click New canvas in the top right corner.
- A blank canvas will open in a new window, then you can start typing to add content to your canvas.
Tip: Create a new canvas from anywhere using the /canvas slash command.
Mobile
- From the Home tab, tap Canvas at the top.
- From the Canvas view, tap Create.
- A blank canvas will open. Start typing to add content to your canvas.

Once you’ve added content to your canvas, you can rearrange it by clicking and holding the six dots icon and dragging the content to a new location in the canvas.

Work on and collaborate in a canvas
Canvases are designed with collaboration in mind. Share your canvas to involve multiple editors, leave comments on canvases and mention people in the body of a canvas to notify them.
Tip: Review our guide on Sharing, access and security for canvas to learn how to share and assign permissions to canvas.
Edit a canvas
To edit a canvas, all you need is Editor access. Simply open the canvas, and start typing to make any changes you’d like.
Tip: If you have View only access to a canvas but need to make edits, you can Request edit access by clicking the View only button in the canvas header. A notification will be sent to the creator of the canvas to approve or deny your request.
Add comments to a canvas
You can use comments in a canvas to leave feedback or start a discussion. Comments on a canvas will behave like Threads, and all new replies will appear in your Threads view if you’ve commented or been mentioned in a comment.

Mention people in a canvas
To notify someone directly in a canvas, mention them by using the @ symbol, followed by the member's name. As long as the canvas has been shared with the person you mention, they will receive a badge notification next to the Canvas view in their sidebar.
Members you mention in a canvas who do not have access permissions to the canvas will not be notified.
