Tuesday, July 21, 2026 · 2 sources

Substack has introduced a new tool to help users identify content that may have been written by AI. The tool can scan various types of text on the platform to estimate the likelihood of AI-generated content.

Substack, a platform for writers and readers, has introduced a new tool to help users determine whether the content they're reading may have been written by AI. This new feature 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 aims to increase transparency and trust among users. The introduction of this AI detection tool reflects the growing concern about AI-generated content and its potential impact on online platforms. By providing users with more information about the content they're reading, Substack hopes to promote a more informed and engaged community. The tool is designed to provide an estimate, rather than a definitive answer, and users will need to consider the results in context. As AI technology continues to evolve, it's likely that we'll see more platforms introducing similar tools to help users navigate the changing online landscape.
