Substack has announced a new partnership with the AI-detection firm Pangram to enhance content transparency on its platform. This initiative introduces tools that allow users to identify the extent of AI involvement in written content. The move aims to address growing concerns about the proliferation of AI-generated text and its impact on digital trust.


Addressing the Rise of AI-Generated Content

The internet is seeing a significant increase in AI-generated text, with some estimates suggesting it comprises up to 40% of content on certain platforms. Substack identifies this as a core problem, coining the term "Claudefishing" for when readers unknowingly engage with non-human writing. This trend undermines the trust between creators and their audiences, which is crucial for the platform's ecosystem.

A New Partnership for Transparency

In response, Substack is integrating Pangram's leading AI-detection technology directly into its app and website. Users can now scan notes, replies, and posts over 100 words to receive an estimate of human versus AI authorship. This feature is user-initiated, providing a tool for discernment rather than imposing a blanket judgment on content.

Empowering Creators and Readers

The platform is also rolling out features specifically for its writers to foster transparency with their readership. Creators can now include a "How I make this" statement to explain their workflow and use of technology. Additionally, they have the ability to run Pangram's analysis on their own drafts and report any perceived inaccuracies.

Substack's Vision for an Authentic Digital Space

Substack emphasizes that this initiative is not an indictment of AI tools but a commitment to authenticity and reader choice. The company itself uses AI for software development and other operational tasks, supporting creators who use it thoughtfully. The goal is to prevent a "race to the bottom" where inauthentic content devalues human creativity and connection.

Future Developments and Community Feedback

This launch marks the beginning of Substack's strategy for navigating the AI era, with further developments planned. The company is considering features that would allow users to set preferences for AI-generated content and give creators more ways to signal their value. Substack is actively soliciting feedback from its community to guide these future enhancements and establish new platform norms.


Substack's collaboration with Pangram represents a significant step toward maintaining authenticity in a digital world increasingly populated by AI. By prioritizing transparency and user choice, the platform aims to reinforce the value of human-centric content. This proactive approach positions Substack as a key player in shaping the future of responsible content creation and consumption.
