Substack Adds AI Detector to Help Readers Spot AI-Written Content
Substack is introducing a new AI-detection tool powered by Pangram to help users identify AI-written content. The feature scans posts, notes, replies, and comments to estimate how much text may have been generated or assisted by AI, aiming to increase transparency on the platform.

Substack has launched a new AI-detection tool to help readers determine whether content they're viewing may have been written by AI. Powered by the company Pangram, the tool scans posts, notes, replies, and comments to provide an estimate of how much text could be AI-generated or written with AI assistance, according to a blog post published on Tuesday.
This matters because AI-generated content is becoming increasingly common across the web, and it's not always easy to tell what's written by a human and what's not. With this tool, Substack users can get a clearer sense of the authenticity of the content they're reading, making it easier to trust the sources they follow. The feature is designed to increase transparency and help users make informed decisions about the content they consume.
If you're a Substack user, you can start using this tool right away. Open your Substack app or website and look for the new AI detection feature in the settings or post options. Try it out on a few posts to see how it works and get a better understanding of the content you're reading.
