An anonymous reader quotes a report from Quartz: Shelley is an AI program that generates the beginnings of horror stories, and it's trained by original horror fiction posted to Reddit. Designed by researchers from MIT Media Lab, Shelley launched on Twitter on Oct. 21. Shelley, named after Frankenstein author Mary Shelley, is interactive. After the program tweets a few opening lines, it asks people on Twitter to continue the story, and if the story is popular, it responds to those responses. Using information from 140,000 stories from Reddit's r/nosleep, Shelley produces story beginnings that range in creepiness, and in quality. There's some classic "scary stuff," like a narrator who thinks she's alone and then sees eyes in the dark, but also premises one can only imagine are Reddit-user-inspired, like family porn.
