I think this is called "style transfer" and you can find an example at https://neuralstyle.art/ Photoshop and Corel Painter have been able to do this for years but only with simple styles like changing a photo into a chalk drawing. Source: about 1 year ago

Thank you. I should say that this was created using neuralstyle.art with a style transfer. Really powerful tool! :). Source: over 2 years ago

I primarily use https://deepdreamgenerator.com but I have been looking at the text prompts at https://nightcafe.studio Not sure how I will use it yet but did do a series using a collection of my wife's haikus as prompts. I also have accounts on https://neuralstyle.art and ArtBreeder and Playform. Source: almost 3 years ago

The only thing I know with half of those features that's discontinued is the old Darkroom app but that doesn't tackle some of the bigger compatibilities. Source: about 2 years ago

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

I use DarkRoom. Full screen, no distractions, no "fancy" auto-formatting. Source: about 3 years ago
