About WhoDunnitAI
Step into the interrogation room. Interview AI suspects with your own voice, catch their lies, and accuse the killer to their face. Solve the murder at Blackwood Manor, if you can. Interview time is free but limited, or use your own OpenAI key for unlimited time. WhoDunnitAI is free to play, but the live suspect voices run on gpt-realtime-2, and every minute of interrogation costs real money. If you enjoyed the case, a donation of any size helps cover the AI bill and keeps the investigation going.
