Wombo
My pal Xina introduced me to one of those phone apps that's probably evil and collecting data on me and destroying culture as we know it, or whatever, but is just so damn cool, called Wombo.
Wombo is an AI that creates art in one of about twenty styles ("Baroque," "Etching," "Fantasy Art," "Steampunk"...). You put in some keywords, choose a style, and let it rip for a few seconds. Next thing you know, it generates art.
The novel I'm trying to work on, set in the early 1900s in Portland, includes an actual historical event where the working girls from the brothel down in Old Town rode their bikes through the respectable part of downtown, past City Hall, in their scanties, ringing their bells, to drum up business.
So I put "1905 Bike Prostitutes*" into Wombo and selected the "Pastel" style...and behold!

*Yes, "sex workers" would be more correct, except, you know, 1905.
