It is based on MarkDown. But it uses Pandoc for input and output, which if I understand it right can read and save LaTeX files (but this will likely not preserve much LaTeX markup; MarkDown is much simpler and does not fully define a print lay-out). https://github.com/jgm/pandoc
Zettlr does support LaTex references, they both work with text files and they have a similar separation of content and lay-out. It may have LaTeX equations, either Zettlr or SciFlow; I am not sure anymore. https://sciflow.net

(And nowadays LibreOffice has LaTex equations.)
