Substack adds an AI detector to help spot blogs written by no one
Substack is introducing an AI detection tool powered by Pangram to help readers identify AI-generated content on its platform. The initiative aims to increase transparency and combat 'Claudefishing,' where readers are misled into believing AI-generated text is human-written.
Why it matters
As AI content proliferates, platforms are struggling to maintain user trust and protect the value of human-authored creative work.
Substack will now help users determine whether what they’re reading may have been written by AI. A new tool coming to the platform can scan 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.
The tool is powered by an AI detection company called Pangram and is rolling out across the web and the iOS app, with an Android launch coming “soon.” Readers can analyze content longer than 100 words by choosing the “Scan for AI text” option from the three-dot menu in the top-right corner of a post.
