We study this question in the context of online reviews by examining Yelp’s introductio n of an artificial intelligence (AI)-enabled topic nudging tool in 2023. T he feature provides real-time prompts to guide review writers in addressin g key dimensions of the dining experience as they compose their reviews. U sing more than 1.5 million reviews and a differences-in-differences design \, we find that AI-enabled topic nudges significantly reshape the generati on of reviews. First\, they expand topical coverage\, particularly for und errepresented aspects such as service and ambiance\, and lead to longer re views while reducing overall review volume. Second\, reviews become more t extually complex and less readable\, and they receive fewer helpfulness vo tes on average. Further analysis shows that the decline in perceived helpf ulness is mitigated when review content remains concentrated on a dominant dimension\, highlighting the importance of informational focus. Lastly\, we find that the impacts are heterogeneous: less experienced users expand review length and topical coverage more significantly\, whereas experience d users exhibit greater complexity and larger declines in perceived helpfu lness. Our findings extend research on AI and user-generated content by hi ghlighting a distinct mode of AI deployment\, i.e.\, guiding rather than g enerating human contributions\, and by revealing its benefits and unintend ed consequences for platform design.\n DTSTART:20260410T143000Z DTEND:20260410T160000Z LOCATION:Room 255\, Donald E.
