The world's first anti-AI CAPTCHA challenge.
Virtus uses a visual noise generation technique that creates
videos of shapes that are invisible to AI vision systems but
clearly visible to the human eye.
Our lightweight challenge protects websites from bot accounts
and spam, all without tracking mouse movements or using
privacy-invasive AI. It's a simple, effective way to ensure a
space is human-only.

Easy? Go back and pause the video. In the blink of an eye,
the shape will disappear.
The human visual system detects temporal coherence
(stability over time) while AI vision systems only analyze
spatial statistics frame-by-frame. The noise in both regions
is statistically identical, so AI cannot distinguish them.
