New AI Project Allows Users to Interrogate Virtual Suspects in a Murder Mystery Game

Aug 10, 2026

AI Summary

A developer has created a voice-driven murder mystery game where players can interview AI suspects using speech. The project utilizes OpenAI's technology and incorporates features like evidence tracking and time limits to manage costs.

The project is a voice-driven murder mystery game that allows users to interrogate AI suspects using their voice.
It was initially developed 2-3 years ago but has been updated with advancements in voice AI technology.
The game uses OpenAI's gpt-realtime-2.1 model over WebRTC, which incurs high costs, leading to user restrictions and a 30-minute conversation timer.
Each suspect can call a tool when accused, which records the accusation and the evidence presented by the player.
A separate gpt-5-mini model evaluates the evidence to determine its validity, with specific criteria for what counts as valid evidence.
The project is built using Next.js, MongoDB, and Clerk for user authentication.
