Substack Adds Pangram AI Detector for Posts Over 100 Characters as It Pushes Transparency

Summary
Substack said users can now scan posts, comments and replies in its app to estimate how much text was written by humans versus AI.
The Pangram integration applies to any item above 100 characters and is paired with an optional AI Author’s note so writers can disclose how they used AI.
Substack said the tool is meant to encourage transparency rather than punish AI-assisted writing; publishers can also scan drafts before publication and challenge mistaken results.
CEO Chris Best framed the feature as a way to preserve trust and keep "AI slop" off the platform, even if exposing AI-written newsletters could hurt Substack’s reputation in the short term.
The move extends a broader industry shift toward labeling AI-made content across social media, video, photos and music services.
