Substack

Company ● Covered in 6 stories Compare ⇄ + Follow

Substack is a platform for newsletter publishing and writing that recently launched an AI detection tool in partnership with Pangram to identify AI-generated content on its platform. The tool scans posts and comments to estimate the proportion of human-written versus AI-generated text, giving readers visibility into content provenance and allowing creators to disclose their use of AI assistance. The rollout has generated mixed reactions, with some users supporting transparency while others have criticized AI detection as unreliable and potentially damaging to writers' reputations.
