Substack’s new tool tells you who’s been writing their newsletters with AI

Substack has integrated AI detection software to label newsletters that are generated by artificial intelligence. The platform aims to maintain trust with readers by distinguishing human-written content from AI-generated 'slop'.
Why it matters
As AI content proliferates, platforms are increasingly forced to implement transparency measures to preserve the value of human-created media.
Substack has launched a new feature that can show you which of your favorite newsletters are being written using AI.
This week, the newsletter and writing platform announced an integration with the AI writing detection software Pangram that will allow users to scan posts, comments, and replies on Substack’s app to see an estimate of how much of the content was written by a human and how much was AI.
In the short term, the move might be bad for Substack’s business, as it could expose many of the newsletters on its platform that aren’t entirely written by people. That could potentially erode trust in the platform’s ecosystem of independent news and blogs, or even damage its reputation as a host of high-quality content.
