AI Content Is Everywhere on Social Media, Especially LinkedIn

19 days ago

Pangram's Chrome extension scans social media posts to flag AI-generated content, helping users make informed decisions about their attention.
Data from opt-in users shows an average AI-generated content rate of 13.8% across platforms, with variation by platform and content length.
Longform content (over 250 words) is particularly affected, with 25.72% fully AI-generated on average, except on Substack where longer posts are less likely to be AI.
LinkedIn has the highest AI saturation, with over 40% of longform posts flagged as fully AI-generated and accounting for 62% of all flagged AI content.
X/Twitter has the worst combined AI rate, with almost half of articles either fully AI-generated (23.9%) or AI-assisted (22.9%).
Reddit has low overall AI share (4.4%) due to human-authored replies (98.1%), but top-level posts have higher AI rates (11.6%), similar to X/Twitter.
Anti-botting strategies on platforms like Reddit may miss AI-generated top-level posts, which have more audience impact despite lower volume.
The dataset includes over 1 million posts scanned with Pangram's AI detection model, highlighting AI writing as a widespread issue on social media.
Transparency through tools like Pangram's extension aims to help users regain control over their attention in an internet increasingly flooded with AI content.
