Substack's new tool tells you who's been writing their newsletters with AI

Overview

Substack is giving readers a way to estimate how much of a newsletter was written by AI, signaling a broader shift toward transparency around AI-assisted content. Substack has launched a new feature that can show you which of your favorite newsletters are being written using AI. This week, the newsletter and writing platform announced an integration with the AI writing detection software Pangram that will allow users to scan posts, comments, and replies on Substack's app to see an estimate of how much of the content was written by a human and how much was AI.

Key Takeaways

  • In the short term, the move might be bad for Substack's business, as it could expose many of the newsletters on its platform that aren't entirely written by people.

    That could potentially erode trust in the platform's ecosystem of independent news and blogs, or even damage its reputation as a host of high-quality content.

  • "This is good use of AI," Substack CEO Chris Best said.

    "When I used to pitch Substack to writers, one way I would do it is ...

  • [S]oftware should do everything else, but I think you do want the person to do the hard part.

    " The feature will be available in Substack's app for any post, note, reply, or comment above 100 characters.

In the short term, the move might be bad for Substack's business, as it could expose many of the newsletters on its platform that aren't entirely written by people. That could potentially erode trust in the platform's ecosystem of independent news and blogs, or even damage its reputation as a host of high-quality content. But in the long term, AI-detection features could help keep Substack free of "AI slop" and encourage more users to trust what they're reading was written by a person, or at least better understand when it's not.

Substack joins several platforms that are leaning toward labeling AI content as such, especially now that AI is playing a greater role in the creation process. Photos and videos generated with AI are labeled on social media sites, while music streaming services have more recently begun labeling and, in some cases, penalizing AI-generated music. "This is good use of AI," Substack CEO Chris Best said.

"When I used to pitch Substack to writers, one way I would do it is ... we'll do everything for you except the hard part," he explained in an online chat with Pangram's founder, Max Spero. "You have to have something - an idea that's worth reading, that's worth caring about, that's worth sharing.
