Ghost Font: A font that humans can read but AI cannot
Points and comments are a snapshot, not live.
Ghost Font uses moving dots to hide messages from AI while remaining readable to humans.
Ghost Font is an experimental anti-AI font that renders text as moving dots in a video. Each frame appears as static noise, so screenshots reveal nothing. A decoy message is embedded to mislead AI agents that analyze motion. Tests against leading models like Claude Fable and GPT Sol 5.6 Ultra showed they struggled to decode the real message, often finding only the decoy. The project builds on ZXX, a 2013 font designed to defeat OCR but now easily readable by modern AI. The creator plans to open-source the code and sees potential applications in CAPTCHAs and AI perception benchmarks.
What commenters are saying
Commenters were split. Many found the concept clever but questioned its practical utility, noting AI could be trained to decode it. Several pointed out that the decoy text ("WRITTEN IN GHOST FONT") is visible in static frames, and that analyzing frame deltas would reveal the message. Some readers could read the main text easily but missed the decoy, while others saw only the decoy. Colorblind and mobile users reported difficulty reading the moving dots. A few linked to prior art involving flickering images and noise-based illusions.
