Daily AI Detective — a free daily murder mystery game

Daily AI Detective is a free daily murder mystery game you play in your browser. Every day at UTC midnight a new case opens: a crime brief, a victim, and four suspects — each an AI-driven character with a persona, a hidden secret, and one lie they will defend. In this AI detective interrogation game you question the suspects in free-form chat, cross-examine their alibis, and collect contradictions with a limited budget of questions.

When you think you have cracked it, you get exactly one accusation. Name the killer to win, then share your spoiler-free emoji result — the same case is served to everyone worldwide each day, Wordle-style. The daily case is completely free; Pro unlocks the full archive of past mysteries, extra questions, and hard mode. JavaScript is required to play.
