AI Noir

A text-based whodunit where every mystery is generated by AI. No two cases are the same. You're the detective; everyone has something to hide, but only one is a killer.

About the Game

Key Features

• A new mystery every time. Suspects, motives, locations, and red herrings are generated fresh each session.
• Play however you want. Type natural-language commands or tap the bold keywords that appear in the story.
• Build your case. Collect evidence, organise it by suspect, pin down means, motive, and opportunity, then make your accusation.
• Save and resume. Every turn auto-saves. Come back days later; your case is waiting.
• Polish. Dark and light themes, high-contrast and colorblind-friendly palettes, background music, sound effects, and text-to-speech narration.

⚠️ Before You Play

AI Noir uses LLMs to generate each case, so you'll need an API key with one of the supported providers:

• Google AI Studio (get your free API key) for Gemini and Gemma models
• Groq (get your free API key) for Llama models

After signing up, paste your API key into the Settings screen on first launch. Your key stays on your device; nothing is sent elsewhere.

How to Play

• Starting a case: From the main menu click Start New Case, pick a difficulty (Easy for 3 suspects and 2 witnesses, Hard for 5 suspects and 3 witnesses), and optionally set a theme like "Victorian London", "1950s Hollywood", or "space station". Leave it blank for a random setting.
• Investigating: Type commands like "examine the letter", "ask Jane about the argument", or "go to the library" – or simply click the bold keywords in the narrative and the game fills in the action for you.
• Building your case: Open Case Files from the top bar to review evidence, people profiles, locations, deductions by suspect, and your personal notes.
• Making the accusation: When ready, open the Accuse tab. Drag evidence into Means, Motive, or Opportunity, pick your suspect, and submit. The button only unlocks when everything lines up.

Settings & Polish

• Themes: Dark, Light, or follow system
• Accessibility: High-contrast mode (WCAG AAA), colorblind-friendly palette, adjustable text size
• Audio: Noir soundtrack, sound effects, and text-to-speech narration with six playback speeds
• Language: English (more languages coming soon)
• Gameplay: Choose whether the game ends when solved or stays open for further exploration

Achievements

AI Noir tracks your detective career. Cases solved are tallied over time, and achievements unlock as you demonstrate skill: solving the pre-game puzzle, finding every piece of evidence, closing a case fast. Stack enough of them up and something new becomes available.
