Over Half of Online Content Now AI-Generated, Report Reveals

A groundbreaking analysis of 65,000 URLs published between 2020 and 2025 shows a dramatic shift in online content creation.

The Numbers

In May alone, AI-generated articles reached 51.72% of published content, surpassing human-written pieces at 48.28%. This marks the first time machine-generated content has overtaken traditional writing on the internet.

The Reality is More Complex

While these figures are striking, experts warn that precise measurement remains challenging. The growing integration between human writers and AI tools makes it increasingly difficult to distinguish purely AI-generated content from human-AI collaborations.

Why measurement is difficult:

  • Writers frequently use AI as a writing assistant
  • AI tools are integrated into content workflows
  • The line between human and machine writing continues to blur

What This Means

This trend reflects the rapid adoption of language models in content production across industries, from journalism to marketing and beyond.
