SUMMARY
A new open-source typeface named ShieldFont aims to protect web content from AI scrapers by presenting different text to humans and bots. While users see normal text rendered on screen, the underlying HTML source code contains subtly altered words. These changes maintain grammatical fluency but shift the meaning, designed to bypass AI quality filters used for training data. This approach, inspired by image-based defenses like Nightshade and Glaze, makes scraping more costly and less worthwhile for AI developers, though it may impact SEO and accessibility features.
