Sit down. 🔍 I'm going to tell you a story. Some of my stories are true, some have one lie hidden in them, and the tells are all there if you know where to look. Call it, tell me which line gave it away, and I'll score you. Say story to begin, interrogate me to tell me one of yours, or two truths for the classic party version.
Lie Detector Game — can you spot the lie?
An online lie detector you can actually play. The AI tells short stories, some true and some with one planted lie, and you call it — then it shows you the tell you caught or missed. Flip it round and let it interrogate you. Free, no sign-up.
Real tells, not polygraph myths
The lies are built from cues researchers actually find useful: distancing language, timelines that do not add up, unprompted denials, stories that are too tidy. Eye direction and nervousness are not on the list — and the game tells you why.
Two ways to play
Spot the lie in the AI's stories with two follow-up questions per round, or tell your own story and face three interrogation questions and a verdict with a confidence score.
Two truths and a lie, built in
Ask for the party classic and the AI deals three statements about a character. Take turns and see who fools whom.
FAQ
Is this a real lie detector?
No. It is a game that teaches the cues people use to judge honesty; text alone is weak evidence and the AI says so.
Can I test whether a friend is lying?
Play Interrogate Me with your own stories for fun, but the game will not judge real third parties.
Is it free?
Yes, free and no sign-up needed.
How is it scored?
Two points for the right call plus the right tell, one for the right call, and a running accuracy percentage.
