Not sure if this is applicable, but if you're using Word or Scrivener or something, you may want to switch to a plaintext editor like Dark Room or Typora--something that won't underline your spelling and grammar mistakes. It doesn't even have italics or bold to get in your way. Dark Room is a little old, but I found it here: https://codex.jjafuller.com/books/dark-room/page/overview. Source: over 2 years ago

Not sure if anyone else had found this, but while I was doing research for a school project I came across a page, thiscatdoesnotexist.com, it shows a picture of a cat, very time you reload it it shows a different one, If I try to view the source it just shows what to me are just random symbols, maybe a more experienced programmer could find out what they are? And nothing much else to go by, just that, pretty neat... Source: over 1 year ago
