Substack launches AI writing detection tool for newsletters

This tool will scan posts, comments, and replies within Substack's app, providing an estimate of AI versus human authorship. While potentially impacting short-term business by exposing AI-generated content, Substack aims to foster transparency and encourage creators to disclose their use of AI tools, ultimately combating "AI slop" and building user trust.
