Decoy Font: An anti-AI font that hides every letter behind a decoy
Hi, I worked on a new font called Decoy Font. While the font design itself might not look special at first glance, the idea is that it hides each typed letter behind a decoy letter using different spatial frequencies. The presence of the outline in front of each letter makes images and text rendered in this font a lot more difficult for an AI multimodal LLM to read. If you're interested in the full writeup and demo you can read more about it here.
