Designers Isaque Seneda and Gabriel Abrucio have created ShieldFont, a font designed to protect webpages from AI scrapers. It uses ligatures to replace certain words in the rendered on-screen text, while the underlying HTML still contains the altered words that scrapers read.
This lets human visitors see normal content, but AI systems that scrape the page's source code get a subtly nonsensical version. The designers describe it as a practical opt-out from unauthorized AI training.
