WorkingCompany's own claimOfficial ↗

Problem

Nextdoor needed to keep harmful content low on a neighborhood platform where most reported posts are reviewed by volunteer moderators.

Approach

Nextdoor added generative AI to its Kindness Reminder in 2023. When a comment was flagged as potentially harmful, the tool suggested a more constructive rewording. Machine learning and volunteer moderators handled review of reported content.

Results

26%share of users who saw AI-revised text and adopted it, per NextdoorCompany's own claim[1]
15%reduction in creation of content that violates Community Guidelines after exposure to the Kindness Reminder and the AI Kindness Reminder combined, per NextdoorCompany's own claim[1]

Takeaway

Nextdoor reported the 26% adoption for the AI-revised text only. The 15% drop in violating content covers the older reminder and the AI version together.
