If you want to write beautiful documents, LaTeX is undoubtedly the best way to do so. It’s basically a programming language that you can use to make documents, with an easy-to-use syntax that can be made as easy or as advanced as you want it to be. What’s more, gone are the days where you need to set up your own LaTeX environment to write in (though you can), as there are tools like Overleaf that act exactly like Google Docs, but allow you to write in LaTeX with support for packages, too.
