I'm currently teaching math online. I don't have a digital pen and everytime I write math equations I usually write it on softwares that are able to support Latex. Currently I use Xournal++, Geogebra, Libreoffice (with Latex plugin).
- The problem with Xournal++ is I have to type it in a box separated from my document. Please look at this picture below as an example. It can update my formula in near realtime which the feature I'm looking for.
- Geogebra also has the same problem as Xournal++. Although It's smoother and faster.
- Libreoffice is the worst one. I can't see the preview in realtime.
So the spesifications for the software: I can write in main window and the software displays it in an instant. The software doesn't need to compile my text into pdf. Any Web app solution that can do these things is accepted but It has to be able to display pictures. It doesn't have to be using Latex if the software has its own fast way then it's ok. It has to be free and can be installed in Ubuntu. Any help is much appreciated.
