Show HN: Slashy – Custom /commands for Notion to draw, record, and more

I'm an avid Notion user, so I wanted to build something to help me be more productive. My first thought was to create a simple inline canvas to draw using a /draw command, to annotate my pages, only to realize that Notion does not allow you to create custom commands.

So instead I decided to do a bit of a workaround to implement custom commands into Notion (through an extension), and created a couple of them to draw and record your camera and audio. I also made a bit of a SDK to interact with Notion so anyone can create their own plugins with ease, and made the code open source.
