AI | The Verge· July 21, 2026 View original

Summary

Substack has launched a new tool, powered by Pangram, that scans posts, notes, replies, and comments to estimate the amount of AI-generated or AI-assisted text. This feature is rolling out across web and iOS, with Android coming soon, allowing readers to analyze content over 100 words.

Substack has introduced a new feature designed to help its users identify content that may have been generated or significantly assisted by artificial intelligence. The platform is integrating a tool from AI detection company Pangram, which will scan various forms of content, including posts, notes, replies, and comments. This functionality aims to provide readers with an estimate of how much of the text might be machine-produced. The AI detection capability is being rolled out across Substack's web interface and iOS application, with an Android version planned for future release. Users can access this feature by selecting the "Scan for AI text" option from a post's menu, provided the content exceeds 100 words. This initiative reflects a growing industry trend to address the proliferation of AI-generated content and maintain content authenticity.

Why it matters

Professionals in content creation, publishing, and marketing need to be aware of tools designed to detect AI-generated text, as it impacts content authenticity and audience trust.
