AI Mystery / Detective Game Maker
Generate detective mystery games with AI — case files, clue systems, interrogation scenes, red herrings, and LLM suspects that think, lie, and confess in real time. One prompt builds a complete playable mystery. No coding required.
AI Mystery / Detective Game Maker
Generate a detective mystery game from one prompt — case files, clue systems, interrogation scenes, red herrings, and LLM suspects. No coding required.
What an AI Mystery Game Looks Like
Generated mystery games run directly in the browser — crime scenes, case files, clue boards, and interrogation rooms, all rendered in real time. Every suspect is played by a live LLM: alibis are improvised, contradictions are remembered, and every playthrough produces a different investigation.
How It Works — Generate a Mystery Game in Minutes
Enter One Prompt
Type a world name or a mystery concept: "Death Note", "Bungo Stray Dogs", or "a locked-room murder in a foggy harbor town with three suspects".
AI Builds the Case
Auto-generates a complete case: suspects with backstories and secrets, crime scenes, clue items, witness statements, and red herrings — each with original art.
AI Creates the Game
Selects the storyline, writes game logic (clue system, interrogation pressure, accusation milestones), and generates all art assets and BGM.
Publish & Share
Auto-builds and publishes a playable mystery game. Players interrogate suspects and solve the case directly in the browser — no download needed.
Fork & Remix
Any public world can be forked — inherit the case files, characters, and scenes, rewrite the mystery, and publish your own version.
Real Worlds, Real Results
Neta Studio has generated mystery games from real worlds — from a Death Note visual novel to a Bungo Stray Dogs detective mission. Every image below is an AI-generated in-game asset from those worlds, not a mockup. Here is what the AI Mystery / Detective Game Maker produces in minutes.
Death Note: First Judgment — an AI Mystery Visual Novel
A black notebook falls into the hands of a top student — and the case files, crime scenes, and interrogation rooms of the Kira investigation are generated scene by scene. Every background is AI-drawn and ready to play.
ADA Mission: Harbor Ghost — a Bungo Stray Dogs Case Game
One fog-wrapped night with the Armed Detective Agency: the case file is generated, the suspects are LLM-driven, and every clue points somewhere new. A detective mystery game generated from the Bungo Stray Dogs: Yokohama world.
Steins;Gate — World Line AVG: a Time-Travel Mystery
A microwave with a phone taped to it sends a text message into the past — and the case rewrites itself. The AI generates Akihabara's labs, streets, and radio towers as interrogation-ready scenes for a mystery that spans world lines.
A Short Hike — Hawk Peak Ascent: a Cozy Mystery Adventure
Not every mystery is a murder. The AI Mystery / Detective Game Maker also generates cozy investigation adventures — like Hawk Peak Ascent, where a young bird hikes toward one important phone call and uncovers the island's secrets along the way.
Core Capabilities
The AI Mystery / Detective Game Maker generates everything a detective story needs — and wires it together into a playable game:
- Case File System — Every case auto-generates files: victim profiles, crime scenes, evidence items, witness statements, and red herrings — all cross-linked and consistent.
- Clue System — Clues land on a live board; the LLM decides how each clue shifts suspicion between suspects.
- Interrogation Mode — Question suspects line by line. LLM suspects remember every answer, dodge questions, and crack under pressure.
- Red Herrings & Twists — AI plants false leads and surprise reveals — every case has multiple paths and endings.
- LLM Suspects — Suspects are played by a live LLM with distinct voices, memories, and motives. Interrogate them in natural language.
- Browser Playable — Auto-built and published — open the link and start investigating. No download.
