Your stories come to life, one choice at a time
Run the case like a real detective: a crime scene, suspects, clues — and a culprit fixed in advance that the AI will not change along the way. You ask the questions, you cross-check the alibis, you make the accusation.
This is not a fixed text to read: it is an interactive investigation where you decide every step. Question a witness, search a room, confront a suspect — follow one of the suggested leads or type your own move, and the story advances on your decisions.
The culprit never moves. Every case is fully built before your first question — victim, suspects, motives, alibis, clues — and the AI sticks to it to the end. You investigate against a real solution, not against a story improvised as it goes.

1. Pick your case: today's case, or one from the catalogue.
2. Investigate chapter by chapter: interrogate the suspects, examine the scene, cross-check the testimonies. Your case file fills up as you go — suspect sheets, clues, loose ends.
3. Accuse: when you are sure, name the culprit. You only get one accusation — instant verdict, a score out of 100, then the full reveal of what really happened.
Every day a brand-new case goes live: the daily mystery. A setting, a victim, suspects who all have something to hide — and the pleasure of being among the first to solve it.
Past cases join the catalogue: play them whenever you want, and compare yourself with other players — how many detectives tried the case, how many found the culprit.
A suspect sheet gathers everything you know about someone involved in the case: their identity, their link to the victim, the motive they could be given, their alibi for the time of the crime, and the grey areas that still do not add up. It is the document every detective keeps at hand — here, your case file keeps those sheets up to date automatically as the interrogations unfold.
One example: the victim's niece, heir to a third of the estate — there is the motive. She claims she stayed in the library from 9 pm to midnight — there is the alibi. But the butler did not see her there before 10:30 pm: there is the grey area.
The sheet is never final. Confront the suspect with that missing hour: she backtracks, invents or breaks — and her sheet changes, often dragging another suspect's sheet with it. One contradiction resolved opens another: that is exactly what drives the investigation to the final accusation.
Straight from the catalogue — a new case is published every day and joins the list.
A sleek, modernist campus carved into a remote valley, where brilliant minds clash over the future of artificial intelligence. The air hums with the quiet thrum of mainframes and the crackle of unspoken rivalries, transforming a heated debate over transparency into a deadly secret.

Open the fileDeep within the fog-choked Briarwood Forest, Albion Lodge stands as a bastion of leather-bound tradition and whispered power. The air is heavy with the scent of old cedar, expensive tobacco, and the metallic tang of a coming storm. Beneath the polished surface of after-dinner cordiality, a viper's nest of ambition and desperation coils, ready to strike.
