Discover the Lie and truth

Features & Capabilities

Lie Detector by the Expression is a Chrome extension that analyzes facial expressions to gauge truthfulness. It tracks eyes movement, blinks, lips, and head cues across nine expressions believed to correlate with lying, based on real psychology studies.

How it works: Record the person’s face, ask a question, then stop to see a Lie or True result. Note that accuracy depends on maintaining a neutral expression, and results are not guaranteed—this tool is for exploratory use.

User Reviews

Users describe Lie Detector by the Expression as a fun, self-administered novelty that feels science-based and can be entertaining when testing friends or family. Many reviews claim it’s accurate enough to be a party trick, with reports of catching someone in a lie or validating truth. However, several reviewers warn it’s not a genuine forensic tool—more of a game—and note inconsistent results. A few question the authenticity of the reviews themselves. Overall, it’s a popular entertainment app with reliability caveats.

Pros

Reported accuracy in user tests, with accounts of catching lies and confirming truths.
Entertaining and fun to use as a party trick or social game.
Self-administered and framed as science-based technology.
Works across multiple testers (friends/family) providing varied usage.

Cons

Not a real lie detector; widely treated as a game and questioned for reliability.
Inconsistent results or misreads in some tests (truth can be labeled as lie and vice versa).
Doubts about the authenticity of reviews and possible bias.

I tried it on my brother when he said he was going to give the candy cane back to my baby brother but he was wrong and the lie detector said he was wrong.
