Interesting idea. I like the idea of a short link for notes. Although I can see myself using it but then forgetting about the app and never using it again.

For stickiness, I’d consider turning it into something like Pocket so I can store lots of URLs there. I’m a big pocket user and can see it being beneficial to get a 4 digit short code that links to the content. I’d use those both on and offline.

This is pretty cool.

I bet this might be useful with an iPad if there was Apple Pencil support.
