Substack launched a new feature enabling readers to estimate how much AI generated a newsletter's content. The move reflects growing pressure for transparency around AI-assisted writing.

The platform's detection tool allows subscribers to assess the likelihood that artificial intelligence contributed to newsletter composition. This addresses rising reader concerns about undisclosed AI usage in published content. Substack joins other platforms grappling with AI transparency. The feature arrives as creators increasingly use AI writing assistants for drafting, editing, and content generation across digital publishing. The tool signals a shift toward voluntary disclosure standards in newsletters. Rather than banning AI-assisted content, Substack opts for reader visibility—letting audiences decide which publications align with their preferences. Creators maintain control over their disclosures. The feature provides data without enforcing mandatory labeling, placing responsibility on writers to communicate their process to subscribers. The move comes amid broader industry debate over AI content authenticity and reader trust in digital publishing.
