Substack adds AI detection tool for user content
The publishing platform Substack has launched a new tool to help users identify content that may have been generated by artificial intelligence. The feature scans posts and comments to estimate the proportion of AI-written text.

Substack, a platform for newsletters and online publishing, has introduced a new feature designed to detect content written or assisted by artificial intelligence. The tool will scan posts, notes, replies, and comments to provide users with an estimate of the AI-generated proportion within a text.
The AI detection capability is powered by a company named Pangram. The feature is rolling out to the web and the iOS application, with an Android version expected soon. Users can initiate a scan for AI text on content longer than 100 words by selecting an option from the post's top-right menu.
This development comes as the use of AI in content creation becomes more widespread. Substack stated the tool aims to enhance transparency on the platform and assist readers in discerning the origin of written material. The company promotes this as a step towards a more authentic digital publishing landscape.
The introduction of the AI detector reflects broader industry concerns about the impact of generative AI on content integrity and authenticity. Substack's move aims to provide users with more information about the content they consume on its service.
