ShieldFont fights AI scraping by handing crawlers the wrong words
ShieldFont, a web font developed in October 2025 by Isaque Seneda and Gabriel Abrucio with support from Playtype, displays one set of words to human readers while serving different words to automated scrapers. The technique preserves grammar and context while returning incorrect text to crawlers attempting to extract data from a page's source code.
Why it matters: Organizations seeking to protect proprietary content or training data from unauthorized AI scraping should evaluate ShieldFont as a practical obfuscation layer, though the robustness against determined scrapers remains unproven.

ShieldFont fights AI scraping by handing crawlers the wrong words
ShieldFont is a web font technology that displays one text to human readers in their browser while serving different text to automated scrapers harvesting HTML source code. Developed by Isaque Seneda and Gabriel Abrucio with support from type foundry Playtype since October 2025, the tool maintains identical grammar and URL while delivering divergent content based on access method.
Why it matters: Content creators and publishers using ShieldFont can reduce exposure of their text to artificial intelligence (AI) training scraping, though scraper operators may adapt their techniques or the approach's effectiveness at scale remains unproven.
