Ghost Font

Ghost Font is an experimental anti-AI font tool from Mixfont that encodes written messages using animated dot motion in a downloadable video clip. The letters are composed of dots indistinguishable from the background in any single static frame, making screenshots reveal nothing while human eyes can follow the motion to read the text. Each generated video also contains a decoy message designed to mislead AI models that attempt to analyze the motion patterns. The tool runs entirely in the browser without sending data to any server, and users can type a message, preview it live, and download the video to share. It was created as an experiment exploring the limits of AI visual perception and whether human-readable visual communication can remain opaque to leading multimodal AI models.
