I need to write Mathematics, but I would like to avoid Latex for quick notes that I wish to send to colleagues. So I would like to have somewhere to write with some sort of pen, in such a way that

1) what I write appears on the display of my computer (please note that I don't have an iPad, just a Macbook)

2) it gets saved on my computer when I finish.

These are just quick notes, so no special drawing features are required (on the contrary, the simpler/cheaper the better).

What should I consider? Since I own a Macbook, also writing on the built-in trackpad would be fine, but I've heard that the Inklet app slows down the computer in a very nasty way...

Thank you very much in advance.

There are also the Wacom tablets, I've used them before and I can say that they worked very well.

They can be expensive but there are a few cheaper ones like the Intuos S, I believe it was. It's specifically a drawing tablet but you could use it for writing.

Here it is:


And for the software, you could use Krita (a free painting app) or Photoshop CC. You could also find other apps in the Mac Store as well.

EDIT: There is a video I found:


He's using Windows but there's a version of OneNote available for Mac. It converts the hand written equations into text. It's awesome!
