Any stories that have been written by AI are marked as such (they are categorized as user submission stories where the author is credited as the AI model). Interestingly the lowest ranked story on the site is one of those, although that was created with an older model. I had never thought of the site as being an "AI product" personally. I just wanted an excuse to play around with web sockets initially, but if I can improve the AI player maybe it will eventually go more in that direction.
