Dead bodies, shadows, blood and limbs make up nail-biting stories for Halloween -- but these tales are now being told by an AI bot on Twitter called Shelley.

Shelley was developed by researchers at Massachusetts Institute of Technology (MIT) and has been telling scary stories since Oct. 23. The bot is named after Mary Shelley, the author of Frankenstein. Shelley brings AI and humans together to create and share scary stories on Twitter.

The bot is described as a “deep-learning powered AI” who “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.”

People can reply to her stories on her Twitter account @shelley_ai. Shelley then writes along with what humans tweet. Rules on how to write creepy stories with the bot can be found here. People can read full stories on Twitter or on

Shelley tweets new story every hour. Here’s an excerpt of one of the stories called #Grandmother:

I gave my curiosity and I went into the kitchen to grab a spare knife. I was startled by the whirring noise, in front of me. I looked over and saw my grandmother, rocking back and forth with her knife and some sort of crucifix.
