Well, I use (Lua)LaTeX for exactly that kind of thing (for the notes I want to be searchable and archived in a repo; for other stuff just writing by hand on paper is usually the best solution, because I don&#x27;t actually need that much notes to be stored as nifty .tex &#x2F; .pdf files -- and for less math-heavy stuff, .md &#x2F; pandoc toolchain is often enough).<p>To make LaTeX writing a bit less &#x27;heavyweight&#x27;, I maintain a .sty file for packages I use often + a template where I can just start writing + vim setup for editing the files + compile with latexmk.<p>When it comes to syntax and stuff like that, after writing my math B.Sc. thesis and who-knows-how-many homework reports with more or less same combo of packages and tools, I already know it and learning to use LaTeX no longer feels like an obstacle (..it&#x27;s a cost I&#x27;ve already paid).<p>Whether a similar solution would be worth the effort for <i>you</i> depends on how much things LaTeX is good at you anticipate writing in the future. Academic papers, homework, stuff like that? Yes, it might be useful. Some random notes? Maybe not.
