Once you're logged in, simply press the 'New drawing' button. You will have the option to either copy or open the link directly. In Notion, you can use the
/embed command and paste the generated URL. All drawings are visible to anyone who has the URL, but only you can edit them. Works best with pen input (like a wacom or surface pen).
Note: Google may log you out after a while, just go back to the homepage at notation-gcp.appspot.com to log back in so you can edit your drawings.
Pressure sensitivity (using the Pointer events API)
Note: under Linux, start Firefox with
Dark and light mode support
Just like in Notion. Comes with the colors to back it up. (Note: picking a mode is only for logged in users, by default the light mode is used).
Usable in Jupyter Notebook
I wanted to draw something in a Jupyter Notebook, and apparantly it works just fine. I quickly cooked up this code snippet (height is optional, but I prefer to put in front of the rather long URL):
I can't edit my drawings anymore?
You were probably logged out of your account. You will need to login again on the homepage. If you still can't edit your drawings, try opening the link in a new tab.
Can I edit my drawings inside the desktop or mobile app?
Not really. I need to verify you are logged into the corresponding Notation account to allow editing, and it's currently virtually impossible to log into Notation with your Notion app.
Will this always be free?
Probably, unless it uses more resources than Google App Engine allows on their free tier. Either way, you can of course host your own instance.
You can contact me at firstname.lastname@example.org, or through the slack linked below.

The backend is written in Google Go and runs on Google Appengine. Source code is available on github. I'm not a front-end developer by any means and it's been 4 years or so since I wrote Go code, so both codebases are not as clean as they could be.
