If you’ve been using Obsidian for a while, you’ve probably seen Canvas in the sidebar and dismissed it as a whiteboard gimmick. That reaction makes sense—an infinite blank space with no obvious starting point isn’t exactly inviting. But Canvas isn’t a whiteboard—it’s where you go when your notes can’t hold the thought you’re trying to work through. Once that clicks, you’ll wonder how you have been thinking without using Obsidian Canvas.

Obsidian

Obsidian is a note-taking and database creation app that lets you store notes privately, so others can’t see them unless you share them. It also has robust third-party app support, so you can customize everything just the way you want it.

What is Obsidian’s Canvas feature?

How does this feature work?

Canvas is a core plugin in Obsidian—it comes with the app and is enabled by default. You can check it by going to Settings > Core Plugins. The feature is accessible as a button on the left sidebar ribbon—clicking which creates a new canvas file in your vault.

Now, the canvas file uses a .canvas extension, not .md. Unlike standard Obsidian notes, it isn’t a Markdown file—it’s based on an open format called JSON Canvas, which Obsidian developed and open-sourced under an MIT license. Under the hood, it’s just JSON, so if you open a .canvas file in a text editor, you can read the structure directly.

Unlike regular notes, a canvas gives you an infinite blank space. There are no pages, scroll limits, or fixed dimensions. You can zoom in and out, pan in any direction, and expand as far as needed. Inside a canvas, you can add three types of elements:

• Cards: Freeform text blocks you create directly on the canvas by double-clicking anywhere on the background.
• Notes: Existing notes from your vault. You can drag them in from the file explorer. They appear in fixed boxes, and you can edit them directly from the canvas.
• Media: Other files in your vault—images, PDFs, even web pages. Like notes, these render directly on the canvas.

Managing Canvas elements

Once you’ve added cards, notes, and media, you can create connections between them. Simply hover your cursor over the edge of any card and a small dot appears—drag from that dot to another card to establish a connection between the two elements. You can label these connections and set the arrow direction as well.

You can also create Groups, which let you visually cluster cards together. Select multiple cards by dragging a selection box around them, right-click, and choose Group. You can assign a label and color, which becomes useful as your canvas grows.

Navigating the Canvas

To navigate through a canvas, you can hold right-click and move your mouse. This will let you move through the canvas. You can also use the scroll wheel to move vertically, and Shift + scroll to move horizontally. Use Ctrl + scroll to zoom in and out, and press Ctrl + 1 to zoom to fit all elements on the screen.

What can you do with Obsidian’s Canvas feature?

What’s the typical Canvas workflow

The most natural way to use a canvas is to open it, create cards to help you materialize whatever you’re thinking about, and start connecting them. You can move cards around freely until the layout starts to make sense—it works like a freeform mind map where you control the structure entirely.

That said, instead of creating new cards, you can also drag existing notes from your vault directly onto the canvas. From there, you can re-arrange them, connect them with lines, and move things around until the relationships become clear.

As mentioned earlier, these connection lines are purely visual—they don’t turn into actual links in your vault. However, the notes render live, and you can edit them directly from the canvas. So if you’re viewing two notes side-by-side and realize they should be linked, you can simply edit one and add a wikilink without leaving the canvas.

Obsidian Canvas vs. Graph view

If you use Obsidian you already know about Graph view—it’s start feature. Graph view shows all your notes along with the connections you’ve created through bidirectional linking. It’s a useful way to explore what you’ve already built and get a sense of how your vault is structured. But it’s read-only. If you notice an isolated note that isn’t linked to anything, you can’t connect it directly to another note from the Graph view. You have to open the note and add the link manually.

Canvas takes the opposite approach. Instead of showing everything that already exists, it gives you a blank space where you decide what to bring in. You drop in the notes you’re actively thinking about, then draw connections yourself. Once a connection feels solid, you can edit the note right there and add the wikilink.

Canvas also enables something the Graph view can’t do at all: placeholder ideas. If a connection between two notes sparks a third idea that doesn’t exist yet, you can create a text card on the canvas and link it to your notes. If that idea turns into something more substantial, you can right-click the card and select “Turn into file” to convert it into a real note. From there, you can add proper bidirectional links and integrate it into your second brain.

How I use Obsidian’s Canvas to help me think

It’s like a whiteboard for everything

When I have a lot of fuzzy thoughts circling in my head—ideas that feel related but haven’t fully formed yet—I open a canvas and dump everything in as cards. No structure, no order—just getting everything out.

Then I start connecting the cards and pulling in relevant notes from my vault to build a web of related ideas. Moving things around and drawing connections helps me see what actually relates, and what the underlying structure looks like.

Sometimes I’ll create a card and realize it fills a gap in my existing notes—an idea I’ve been relying on but never explicitly written down. I turn those into files and link them properly.

There isn’t a right (or wrong) way to use Obsidan’s Canvas feature

Canvas doesn’t enforce a specific workflow. You can use it as a mind map, a project planning board, a way to review research before writing—whatever fits how you think. That flexibility is genuinely useful, but it’s also likely why many people don’t end up using it.

When a tool can be anything, it’s easy not to know where to start—so it just sits there. That’s a shame, because once it clicks, Canvas becomes one of the most useful features in Obsidian.
