Perdify: AI Detective Game
Interrogate murder suspects
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Pick a case, question AI suspects, uncover evidence, and solve mysteries built on a grounded truth engine that keeps the story coherent.
A locked room. A handful of suspects. One of them is lying to your face.
Perdify is a cinematic AI murder mystery — a growing library of closed-circle cases where every interrogation is improvised. Pick a scenario, walk in,
and start asking questions. The imposter is in the room with you.
THE CASE FILES
Every case is a self-contained mystery with its own setting, cast, and timeline — from blacked-out 1970s hotels and overnight European sleeper trains
to country-house dinners, mountain retreats, isolated research stations, and yachts at sea. New scenarios released regularly.
VOICE OR TEXT
Speak naturally and hear suspects answer in their own voice — or switch to text and read every word. Both modes pull from the same live AI, so
behavior, motives, and lies stay consistent however you play.
EVERY SUSPECT IS A STORY
Each character has a distinct personality, knowledge, alibi, and motive. The imposter knows what really happened — and will lie strategically, change
their story, redirect blame, and play on your assumptions.
READ THE TELLS
Perdify's behavior engine flags micro-tells in real time: evasive answers, hesitation, rehearsed phrases, contradictions. The signals are always there.
You just have to spot them.
EVIDENCE & CONTRADICTION
Search rooms. Collect physical evidence. Cross-reference statements on the case board. The truth lives in the gaps between what suspects say.
MAKE THE CALL
Limited rounds. Limited questions. Limited accusation tokens. When you're ready, name the imposter. Get it wrong, and the killer walks.

A SAMPLE OF THE LIBRARY
• Blackout at the Beaumont — Manhattan, July 1977. The lights go out, and a federal judge is dead in the penthouse elevator.
• Yacht Midnight — A poisoned nightcap in still water.
• Last Train to Zagreb — A locked berth, an empty case, and a storm with no exits.
• Nádraží — Prague Central Station, New Year's Eve 1989. The ghosts of the old regime die hard.
• Dinner Party at Ashworth Manor — A country house. A long table. One chair empty by morning.
• …and more, with new cases dropping regularly.
Mature themes — murder, deception, adult drama. No gore, no explicit content.
