Play as a detective and solve multiple cases by interrogating individuals tied to the case through voice-based conversations. Powered by generative AI, every individual responds with unique, context-driven replies, helping you piece together the evidence to crack the case.
Detective Bureau
Steam
You're a detective working the phones. A folder of notes, a desk, and a city full of secrets. Solve intricate cases by speaking directly to the people involved, and hear them respond, unscripted, through real-time generative AI. Each conversation is different, shaped by what you say and how you say it. Your job is to uncover the truth, one unpredictable exchange at a time and close the case by submitting a final report identifying the guilty party, their motives, and their means.
----------------------------------------------------------------------------------
Use your case file to study the evidence and learn about the people involved. Apply sharp deduction to figure out who did it, why they did it, and how it all happened.

Every voice call is dynamic. No repeated dialogue. No decision trees. Just you and whoever’s on the other end.

Examine the evidence, link the details, and use what you uncover to expose the truth.

Identify the guilty party, submit your conclusion, and see if you were right. There are no take-backs.

Your conversations shape the outcome. Every case is its own mystery, and every answer is up to you.
