org-fc VS olivetti

I have tried org-drill but decided against it and other Emacs options including chenyanming/anki.el, eyeinsky/org-anki, l3kn/org-fc and abo-abo/pamparam in the end. They all work as advertised and all use or a slight variation of the same SM2 algorithm used by Anki. They all use this one as it is publicly available.

org-fc has been great to work with. It's been easy to confirm and use. The dashboard is also nice. Do have a look.

org-fc can handle what you would like to do. You can find install instructions here, I don't know exactly how doom works but I imagine you can get what you need there.

I also use writeroom because I prefer its simplicity, but worth mentioning that olivetti is the more popular writing mode.

There are nice looking distraction-free setups with https://github.com/joostkremers/writeroom-mode or https://github.com/rnkn/olivetti or https://github.com/joaotavora/darkroom or https://github.com/rougier/nano-emacs

For batteries-included packages that give you dedicated prose-writing modes, see also olivetti and writeroom-mode.

You could use olivetti-mode or Writeroom mode.

Another option is the Olivetti package. https://github.com/rnkn/olivetti

Don't have a specific tutorial except to suggest setting org-mode to use olivetti and a nice variable pitch font for writing prose. You might also like the poet theme.

If you want to try out some third-party packages in the beginning, I think the most "bang-for-your-buck" you'll get is with Avy. Also, expand-region. And specifically for writing: olivetti-mode, flyspell, dictionary, and Nicolas Rougier's Nano and Elegant Emacs setups.
