Pangram: Over 40% of LinkedIn Long Posts AI-Generated
Pangram Labs, maker of an AI-text detector, analysed social-media posts users actually encountered across platforms and found a high prevalence of AI-generated text. The study reports that more than 40% of LinkedIn posts longer than 250 words were classified as fully AI-generated. Pangram claims a 99.98% detection accuracy, supported by independent studies at the University of Maryland and the University of Chicago. Across the sampled platforms the average AI share was 13.8%, with longer posts more likely to be AI-generated; on X Pangram classified 25% of content as fully AI-generated and 23% as AI-assisted. LinkedIn has publicly commented on the rise of so-called "AI Slop" and said it will respond to the trend.
Pangram Tool Tested for Detecting AI‑Generated Texts
Major German newsrooms used the AI-detection tool Pangram to check whether politicians’ speeches and guest articles were written by humans or generated by AI. Pangram is a product of startup Pangram Labs, founded in 2024 by Stanford alumni Max Spero and Bradley Emi. The company trains its detector using a technique called “negative mining,” where cases the model misclassifies (false positives and false negatives) are added to the training set to improve accuracy. t3n evaluated Pangram on its Tool Time show and attempted to trick the detector with a deliberately AI-generated speech. Media reports cited include Frag den Staat, Die Zeit and Focus, the latter reporting a claim that ~9% of Bundestag speeches in 2026 were fully AI-generated.
