Every murder is different. Every suspect has something to hide.
Leverage the tools of the trade: Case Wall, Find Clues, Make Deductions, and Interrogate. Each suspect has an alibi, but one of them is lying. You need to use real skills to solve it.
You are the Detective.
iOS testing runs through Apple’s TestFlight app — install TestFlight, then accept the invitation to find AlibAI inside it.
This isn’t a quick whodunit. This is an immersive story unfolding as you interact, build the case, name your suspect and accuse. Accusation is dramatic and satisfying when right or disappointing when wrong.
Search the manor room by room. Find the murder weapon, examine the evidence, and hear the coroner’s report. Pick locks, dust for fingerprints, and crack ciphers to uncover what the killer wanted hidden.
No dialogue trees. Type your own questions and the suspects answer in their own words — guarded, wounded, indignant, rattled. Press on the detail that doesn’t fit and watch it land.
Pin every suspect, every piece of evidence, every possible weapon to the case wall, and run threads between them until the picture narrows. Means, Motive, Opportunity — work out who had all three. Then accuse.
Everyone who came that night passed through here.
Hone your interrogation skills against characters who think, have excuses, point to each other, show emotion, get angry or clam up, crack under the right pressure of questions. Use the Lie Detector, pick locks, find fingerprints, break cipher codes.
Each case can be solved without deep interrogation, but the Story is there for the immersion and it’s truly satisfying experiencing them deflect or crack.
Ask a suspect in your own words and they respond in theirs. AI is an augmentation, it isn’t the game. Every case is 100% solvable without it. But wow is it fun to have those in story conversations, real historical items written into the backstory. Have a conversation about Dr. Jekyll and Mr. Hyde while searching for tells. It gets immersive.
I can't say for certain, but the master of the house could rub people the wrong way. He had his share of disputes — especially concerning money. I had my own about unpaid wages. But I wouldn't wish harm on him.
A dinner no one lived to finish.
Each case is a complete whodunit — a victim, a tight circle of suspects, hidden motives, and exactly one killer. The setting is the stage; the drama is fresh on top of it. Worlds arrive one at a time, each with its own cast of roles, its own mood, and its own kind of secret.
A gaslit English country house, a storm at the windows, and a family with more secrets than rooms. The first world AlibAI ships with — gothic, intimate, and full of people who'd rather you didn't ask. Murder among the well-mannered, where everyone has an alibi and someone is lying.
A dig site under a wide, cold sky. A foreign patron dead among the trenches, a crew of rival excavators and uneasy locals, and a buried find worth killing for. Our next world: the same deduction, a wholly different cast of motives.
We're sketching settings beyond the manor and the dig — each a self-contained stage for a new kind of mystery, with its own roles, era, and atmosphere. New worlds arrive as themes; the detective work stays exactly as sharp.
The grounds keep what the house won't say.
The Manor is filled by a rotating company of more than twenty suspects — the housekeeper, the gardener, the house lord, the socialite, the weekend guest, and more. Every case deals them new motives, new secrets, and a new culprit, so the faces stay familiar while the truth never does.
Keeper of every key and every routine. She knows which doors lock, which guests linger, and which family secrets stay below stairs. Loyal, measured — perhaps to a fault.
Works the grounds dawn to dusk and sees who comes and goes through the garden gate. Gruff, plain-spoken, and short on patience for the family’s airs — or their unpaid wages.
Built his fortune and his name from nothing, and rules the house as though he built that too. Proud and self-made — the kind of man other people’s grudges collect around.
Poised, charming, and perfectly at ease at the centre of any room. Every warm word is chosen — and behind the poise, an eye always on what stands to be gained.
Charming, well-connected, and always somewhere near the trouble. A guest who seems to know the house better than a guest should — and the family better still.

Challenging mini games guard the evidence: lock-picking, fingerprints, ciphers, and more. Match what you recover to motive, means, and opportunity — and mind the ones planted to mislead you.
The whole family, painted in better days. Study it long enough and you notice who has been left out — and who stands a little too far from whom.
Found locked from the inside, the keyhole freshly forced and a thread of glove caught in the hinge. An alibi as much as an object.
Opens a private route up to the study that no one thought to watch. Whoever held it could come and go unseen.
The port sits untouched beneath a film of dust — save for a single glass poured the night he died. What was in it is the question.
and many more
How it was done is half the puzzle. Each weapon leaves its own mark, fits some hands and not others, and belongs to a room someone had to reach.
A slim silver letter opener from the study desk. Small, but the point is honest — at close range it parts flesh as cleanly as an envelope.
A heavy marble bust from the library plinth. Too heavy to swing — but deadly the moment it is toppled.
Decanted from the darkroom chemicals. Swift, volatile, and gone from the glass by the time anyone thinks to look.
A pillow pressed over the face in the sickbed. No blade, no blood — silent, and terribly intimate.
and many more
Pin every suspect, every piece of evidence, every possible weapon to the case wall, and run threads between them until the picture narrows. Means, Motive, Opportunity — work out who had all three. Ask DS Quinn to verify a link when you have earned the check; she confirms your work, she never does it for you.
Then accuse. Name wisely: the verdict is final. Get it wrong and the trail runs cold — the killer walks free, and that stands.
You have the means and you have the opportunity, Detective. Find me the reason and I’ll sign off on it.
