This Halloween, we present Shelley: the world's first collaborative AI Horror Writer! Shelley is a deep-learning powered AI who was raised reading eerie stories collected from r/nosleep. Now as an adult, and not unlike Mary Shelley - her Victorian idol - she takes a bit of inspiration in the form of a random seed, or a short snippet of text, and starts creating stories emanating from her creepy creative mind. But what Shelley truly enjoys is to work collaboratively with humans, learning from their nightmarish ideas, creating the best scary tales ever. If you want to work with her, just respond to the stories she would start every hour on her Twitter account, and she will write with you the first AI-Human horror anthology ever put together!
