# Substack Deploys Pangram: AI Detection Tool Bets Readers Value Authenticity

> Substack has integrated Pangram, an AI-detection tool that estimates what share of a given post was written by a machine. The feature, launched July 23, surfaces a percentage that readers can weigh when deciding whether to trust or subscribe to a writer. The bet underneath it is a bet on authenticity. Substack is wagering that as AI-generated text floods the internet, a meaningful slice of readers will pay a premium for work they can verify was written by a human, and that visible detection scores help build that trust. It is a contrarian position worth watching. AI-detection tools are notoriously imperfect and prone to false positives, so leaning on one as a mark of credibility carries risk. But the move stakes out a clear identity for the platform in a moment when many rivals are racing to add generative features rather than to certify against them.
