Thirty-five percent of new web content is already AI-generated: the end of diversity

Published on April 29, 2026 | Translated from Spanish

A joint study by Stanford, Imperial College London, and the Internet Archive has uncovered an uncomfortable reality: by mid-2025, 35% of new web pages analyzed were created or assisted by artificial intelligence. This percentage was practically zero before the launch of ChatGPT in late 2022. The speed of this paradigm shift is the most alarming data point, and its consequences for the diversity of digital discourse are beginning to be quantifiable.

Forensic methodology: how semantic homogenization was detected 🔍

The researchers analyzed monthly samples of websites from August 2022 to May 2025, using the historical archive of the Internet Archive and the Pangram v3 detection tool. The results reveal two critical trends: a notable decrease in semantic diversity and an artificial increase in positive sentiment in the text. The study warns that as AI-generated content becomes widespread, the range of available ideas and viewpoints is reduced. Behind this trend, a growing industry is consolidating. Tools like Lovable or Vercel's v0 allow users to create complete websites with a simple text description. According to Wise Guy Reports, the market for AI-powered website creation tools reached $3.1 billion in 2024 and is projected to reach $25 billion by 2035.

Unrestricted publishing or global echo chamber? 🌐

Publishing on the internet is increasingly accessible, but the implications for the quality of discourse are profound. The ease of generating content with AI is pushing the web toward a digital monoculture, where the same linguistic patterns and narrative structures are replicated endlessly. If critical and diverse use of these tools is not encouraged, we risk artificial intelligence not amplifying our voices, but rather unifying them into a single, flat, and predictable tone.

How could the growing homogenization of AI-generated web content affect digital society's ability to innovate and solve complex problems that require diverse and unconventional perspectives?
