Substack is introducing an AI detection tool that allows readers to determine if a post, note, reply, or comment is written by a human or generated by AI. The feature comes from a collaboration with Pangram Labs, an AI detection company. However, as AI writing tools like ChatGPT have become affordable and user-friendly, some creators are leaning on them heavily. Instead of banning AI writing outright, Substack is empowering readers with information. Whether AI detection technology is accurate enough to make this approach effective remains uncertain.
