Summary

Substack, the platform popular for online newsletters, recently launched an artificial intelligence detection feature powered by Pangram. The detector allows users to scan text and get an estimate for how much of it was likely written by AI. But some creators are concerned about the tool’s accuracy and its potential to prompt a “witch hunt” for writers who use AI. Marketplace’s Meghan McCarty Carino spoke with Substack CEO Chris Best about the new feature.
