CounterHelp: Promoting Online Civil Courage Among Young People Through AI-Generated Counterspeech

摘要

We present CounterHelp, a mobile app designed to support adolescents and young people in generating customized counter speech in response to hateful comments on TikTok. CounterHelp allows users to specify counter strategies to combat hate speech. After users share a hateful comment with CounterHelp, it retrieves TikTok metadata to capture its context. Leveraging large language models, CounterHelp generates customised and context-sensitive counter speech in one of four predefined styles, particularly tailored for adolescents. A user experience lab study confirms the effectiveness and usability of CounterHelp and the generated counter speech.
