I am looking for a minimalistic word editor for my creative writing. Basically I would like something like the “notes” app on OSX just with the option to save your writing as a separate file. Does anyone know of something like that?
I like Notepad++. It has more features than you might want, but it is NOT a document formatter. It is nothing like Microsoft. It is single font, which you can make be a fixed-space font for a typewriter look. It loads quickly, saves files easily, keeps backup files, and doesn't take a lot to learn it.
But, it is multi-window, so you can edit more than one file at a time, or look up in one while writing in another. It has some spell-checking ability you can add (or turn on), but it does not have (AFAIK) Grammerly integration.
If you want platform independence, Notepad++ works pretty well, with very similar products being available on Linux and Windows.
Have you considered using Google docs?
