Firasa

Firasa reads emotions and micro-expressions from a live camera, a video file, a photo or a URL, and shows whether a smile actually reached the eyes. Everything runs client-side: the footage never leaves your device, so there is no upload and no stored video of anyone's face. What it is not: a lie detector. No facial signal means lying, and we say so on the site instead of selling that fantasy. Firasa measures expression and timing, not truth. Free to start, no account needed.
