Tool for using iPad as RealTime "Chalkboard" on MacOS?

Due to Covid-19 I'm holding my lectures as webinar from my iMac (WebEx, Zoom, ...). Meanwhile my setup works, but there is one thing I miss a lot: Drawing sketches in front of the class while I talk about it.

Now, that I own an iPad + Pencil I'm looking for any Mac app that would allow me to

sketch on the iPad (simple, symbolic stuff, just like scribbles on a white board)
while talking on the conference software
see my drawing in a window on the Mac in (kind of...) real time (I can put on the shared screen of my conference software)

Any ideas?

Solution 1:

The best tool I have found for this is the iPad app Notability (I am not affiliated, I am a math professor who is also giving all lectures on Zoom). When I share the screen in Zoom (on my Mac), I am able to select "iPad over AirPlay" as the source for the share.

Notability has a "presentation mode" where you can see the UI to select colors, tools, etc. but it broadcasts through the screen share with the UI hidden (in essentially real time). Zoom works really nice here, your video is broadcast on the side of your "whiteboard" surface.

Notability has some nice tools, and works really well with the pencil (I am using an older iPad pro with the first gen pencil). You can use it to simply draw, you can have it do shape recognition and clean up stuff like rectangles, circles, triangles, etc, options to do straight lines. I am using it for my math classes and like it a lot.

Solution 2:

Thanks to the keyword "Airplay", that Morgan Rogers dropped, I found another way I want to document here (but maybe someone still has a better idea ;-) ):

I remembered there was an app called X-Mirage that works as an airplay receiver app for MacOS. So I can set up X-Mirage as a Airplay receiver and send from the iPad from any sketching App I choose (Notability looks promising). A short test setup was very promising.

This way I am totally independent of
