How Sincerity™ Is Measured

Sincerity™ looks at three layers of signal: your voice, your face, and your language.

Voice picks up on tone, pacing, and vocal patterns that shift when what someone says and what they feel don't quite line up.

Video reads facial micro-expressions and body language frame by frame, the small movements that happen faster than someone can control them.

When you upload both audio and video, we combine the two into a single composite score, weighted by how confident each signal is on its own. If your voice signal is strong but the video is unclear, voice carries more weight in the final number, and the reverse is true too.

The result isn't a lie detector and it isn't reading minds. It's a measure of alignment: how closely what someone expresses matches what they appear to feel in the moment. That's sincerity.
