Pick a case, gather clues, interrogate suspects, and solve the mystery — your AI detective agency runs as many interactive mystery cases as you want, with branching dialogue, consistent character motivations, and earned plot twists. Built for mystery fans, writers practicing plot structure, game-night hosts, and anyone who wants Agatha Christie / Sherlock Holmes / Knives Out energy on demand. ## What's included - **Case library** — 50+ pre-built cases across genres: classic whodunit (mansion murder), noir (1940s LA), cozy (small-town bakery), procedural (modern detective), historical (Victorian London), supernatural (ghost story with logical reveal) - **Live case generator** — describe a setup ("missing heirloom at a wedding", "poisoning at a Michelin restaurant"), agent generates full case with suspects, motives, alibis, red herrings, and the true solution - **Suspect interrogation** — every NPC has consistent backstory + motive + alibi + tell; lying suspects contradict themselves under questioning if you find the right thread - **Clue management** — physical evidence, witness statements, forensic reports, financial trails; agent tracks what you've found vs what's still hidden - **Branching dialogue** — accusatory vs sympathetic questioning unlocks different information from the same NPC - **Multiple-solution support** — some cases have ambiguous true answers; some have one provable conclusion; agent honors the case structure - **Earned reveals** — agent doesn't volunteer the solution; you have to actually piece it together; final confrontation locks in your accusation - **Multi-session cases** — pause mid-case, resume days later; agent remembers every clue + suspect interaction - **Writer mode** — analyze your own mystery draft for plot holes, motive consistency, clue placement, fair-play vs cheat detection - **Group play** — host a mystery for friends; agent moderates, NPCs respond consistently, scoreboards detective performance ## Limitations - **Not a video game** — text-driven; visual scenes + maps + animations are imagined, not rendered - **Not a board game replacement** — pairs with physical mystery games (Clue, Sherlock Holmes Consulting Detective) but is a different medium - **Not LLM roleplay free-for-all** — case structure constrains NPCs to in-canon behavior; chaos mode is not the default - **English-first** — Spanish + French + German cases adapt; idiom-heavy noir works best in English - **Not therapy** — entertainment + mental exercise; not a substitute for processing real-life situations ## Best fit Mystery genre fans (Agatha Christie / Sherlock / Knives Out / Only Murders in the Building lovers), writers practicing plot construction + fair-play mystery technique, game-night hosts, solo gamers, and parents looking for screen-light interactive entertainment for older kids + teens. Especially valuable for writers stuck on a mystery WIP — the structured case generator becomes a private writing room for testing motive + alibi + clue logic before committing 70,000 words to a draft that doesn't hold up.
