Become the Lead Detective : ========================== Step into an original, Agatha Christie-style murder case where every story, character, and clue is generated dynamically. Crime Story is a revolutionary AI-powered game that puts you directly in the interrogation room via a familiar messenger interface. Interrogate Suspects: Chat directly with up to 10 unique suspects and witnesses. The advanced AI models control each character, providing persistent, consistent personas and complex backstories. Dynamic Consistency (RAG): Unlike standard chatbots, our system is powered by an advanced on-device RAG engine. Characters remember every question, lie, and piece of evidence you uncover across all chat threads. Use contradictions to expose the truthโ€”the game flawlessly manages the complex, interwoven story history. Uncover the Truth: Challenge alibis, explore motives, and follow the threads of conspiracy. Every answer given by one suspect will influence the knowledge of the others. The Final Accusation: Judge the Case: ===================================== Total Agency: The Accusation tab is always open, allowing you to submit your final case summary whenever you feel the evidence is strong enough. No need to chase irrelevant suspects! AI-Assisted Scoring: Use your compiled notes to write a detailed accusation. The powerful Gemini 2.5 Flash-Lite model evaluates your final submission against the story's hidden truth (Motive, Killer, Method). Get a score based on the accuracy and completeness of the facts you used to prove the case! Key Features & Educational Focus: ================================= Advanced LLM Architecture: Powered by Gemini 2.5 Flash-Lite for deep narrative complexity and combined with a fast, privacy-focused Core ML on-device RAG system to guarantee cross-character consistency. English Practice Tool: Sharpen your writing and deduction skills! Input your questions in any language (Croatian, Spanish, French, etc.)โ€”the app automatically translates your text for the AI and offers real-time spelling and grammar correction. Privacy-First Design: All conversation history and factual indexing are handled on your device. The app DOES NOT collect, transmit, or store any of your personal information or location data.

A stranger has your number. They need help. Everything happens in the chat. Unknown Contact is a collection of short interactive stories that play out entirely as text messages. No cutscenes, no maps, no menus to fight through โ€” just a conversation with someone who is in trouble, and the words you choose to send back. Tap a suggested reply, or type anything you want. Ask about the noise in the vent. Tell them to run. Stay quiet and see what they do. The story is listening. SEASON ONE โ€” 20 STORIES, 80 ENDINGS Every story runs about 15โ€“20 minutes and hides four different endings. Some you stumble into. Some you have to earn by noticing the right detail and asking the right question. HORROR BASEMENT โ€” a stranger, a locked room, one flickering bulb THE BABYSITTER โ€” don't let her answer the phone THE HIKER โ€” the trail markers have names on them SNOW DAY โ€” no footprints ever lead away THRILLER & SUSPENSE THE NEIGHBOR โ€” he knows what's in your apartment LAST TRAIN โ€” the last train doesn't stop where it says THE WITNESS โ€” they recorded who wasn't supposed to be seen WRONG EXIT โ€” every ramp leads back to the same floor MYSTERY THE HOTEL โ€” the room numbers keep changing THE INHERITANCE โ€” the letters already know your name ESTATE SALE โ€” every photo in the album is you WRONG DELIVERY โ€” the box arrived years too early SCI-FI NEW PHONE โ€” the drafts are writing themselves ECHO โ€” your answers never match theirs THE DEEP โ€” a station that won't exist for sixty years THE SIGNAL โ€” eleven names, one blank line, eighteen minutes COMEDY CUSTOMER SUPPORT โ€” it's just a smart fridge. probably. GHOSTED โ€” the haunting has the wrong apartment PROBATIONARY PERIOD โ€” first shift, impossible handbook, review at midnight COLD FEET โ€” forty minutes until a wedding nobody can find WHY IT FEELS REAL โ€ข Type whatever you want โ€” the story understands what you meant, not just what you tapped โ€ข Photos and voice notes arrive the way they would from someone genuinely scared โ€ข Every voice note is captioned, so the sound is atmosphere and never homework โ€ข People tell you their name only once they trust you โ€ข Endings you've found are tracked, so you always know what you're still missing FIVE STORIES FREE, FOREVER One story in every genre is free and always will be.
