Full story

Pangram analyzed long-form content across five social media platforms to determine the prevalence of AI-generated text. The study found that overall, one in four longer posts is entirely written by AI.

LinkedIn emerged as the primary source of this content, with 41% of its long-form posts flagged as AI-written. Although LinkedIn comprised only one-third of the total dataset, it accounted for nearly two-thirds of all detected AI content.

The detection model used in the study is described as conservative, suggesting that the actual volume of AI-generated material on the platform may be even higher than reported.
