Carnacki: The Whistling Room

Carnacki: The Whistling Room is a browser-based, choice-driven, AI-generated horror adaptation of William Hope Hodgson's occult-detective stories (Carnacki, the Ghost-Finder, 1913), and the first of five Carnacki cases.

At Iastrae Castle in the west of Ireland, an empty first-floor room has whistled every night for a week, a wet, hooting sound that has driven the servants out. The new owner, Lord Tassoc, blames a prank by hostile locals. As Thomas Carnacki, armed with candles, chalk and patience, you have to rule out human trickery before you can believe anything worse.

The series continues with The Gateway of the Monster, The Horse of the Invisible, The Thing Invisible and The Haunted Jarvee, all of them Hodgson's own titles. The cases unlock one after another; this listing covers the series. Case 1 needs no account, and the later cases need a free sagaflow.ai account.

How it is made: an AI language model generates the story text. It wrote each case's opening scene when the case was set up and writes every later scene, options included, during play; no scene is written by hand. The cover, the narration voice and the music are AI-generated as well, and our team built everything around the stories.

Every scene offers a few options, and from your fourth decision you can also type your own action, twice per case. A case runs about ten scenes.
