What is Obsidian Canvas and how do you use it to think better?

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.
