Data Shows 41% of Long-Form LinkedIn Posts Are AI-Generated

Pangram estimates that 41% of long-form LinkedIn posts and 30% of short-form posts were likely AI-generated between April and June. The AI detection firm tracked LinkedIn along with X, Reddit, Substack, and Medium, and found LinkedIn had the highest average share of AI content.

A company that produces content for multiple creators stopped using AI to write LinkedIn posts after noticing the increase. The company's chief revenue officer said the platform showed visible signs of AI-generated material and that human-written posts performed better.

LinkedIn added a button that lets users apply AI to polish new posts. The company stated in June that it is taking steps to limit low-effort AI content that lacks unique perspective.

A survey by Use.AI found that 39% of 12,600 respondents across multiple regions said they now change their writing style to avoid sounding like AI. Common changes include shortening sentences and removing em dashes. Gartner reported that half of 1,539 U.S. respondents surveyed in October preferred to do business with companies that do not use AI in their messaging.
