How it plays

Every file, a new secret

Voice interrogation

Hold the microphone and ask in your own words. Suspects reply in character, with their own voice, and remember what you have already shown them.

Spot the lie

Watch for tells, call out a contradiction and put the evidence on the table. Pressure rises, stories crack.

Crime scene

Sweep each scene by flashlight, find hidden evidence and open coded locks before you enter the room.

Close the case

Name the culprit, attach the evidence and the motive. Earn stars, rise from trainee to superintendent.

Good to know

Built for the room, not the feed

No account

There is nothing to sign up for. Your progress lives on your device and is tied to an anonymous identifier, never to your name.

Voice stays optional

The microphone is only active while you hold the button. Prefer silence? Type your questions instead.

Fiction, generated live

Suspects are played by an AI language model inside a scripted case. Their words are fiction and may occasionally be odd. You can rate or report any reply in the app.
