A new Pangram analysis found that long-form social media posts are increasingly AI-written, according to The Decoder. The study says one in four longer posts across five platforms was entirely AI-generated, with LinkedIn leading at 41 percent.
The finding matters because professional networks are becoming a visible testing ground for synthetic writing. AI-generated posts can help users publish more often, but they can also make feeds feel less authentic and harder to trust.
For platforms and creators, the trend raises practical questions about labeling, ranking, and whether audiences will continue engaging with content that feels automated.
