One Weird Trick for Opting Out of Pangram on Substack

Summary

Substack recently integrated Pangram's AI-detection software directly into its app, allowing readers to assess if posts, notes, replies, or comments are AI-generated. This feature, launched around July 21, 2026, has drawn significant criticism, particularly regarding its compliance with EU and UK GDPR regulations. The author highlights potential violations of GDPR Articles 21 and 22, which concern the right to object to processing and not to be subject to solely automated decisions producing legal or similarly significant effects. Substack's privacy notice, last updated May 14, 2026, likely categorizes AI detection under "legitimate interests." However, the article argues that the tool's 1 in 10,000 false positive rate, especially under real-world conditions, could lead to reputational and economic harm for creators, disproportionately affecting non-native speakers or neurodivergent writers. The author contends that Substack's business interest in combating "AI slop" may not override individual data protection rights, especially without suitable safeguards or consent.

Key takeaway

For EU/UK-based Substack creators concerned about the new Pangram AI detection, you should consider exercising your GDPR Article 21 right to object. This action requires Substack to cease processing your personal data via AI scanning unless they demonstrate compelling legitimate grounds overriding your rights. Use the provided template to request their legitimate interests assessment and details on automated decision-making, safeguarding your professional reputation and content distribution.
