AI Mystery Game! Interrogate suspects via messenger chat. Dynamic plot, persistent memory, and a new whodunit case every time. Powered by GPT & Gemini. 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 truth—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.)—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.
