边验证边浏览：一种基于大型语言模型的假新闻检测浏览器扩展

The rampant spread of fake news poses significant risks to public trust and democratic institutions, highlighting the urgent need for effective, transparent, and user-centered detection tools. Existing browser extensions often fall short due to opaque model behavior, limited explanatory support, and a lack of meaningful user engagement. Aletheia is a novel browser extension that leverages Retrieval-Augmented Generation (RAG) and Large Language Models (LLMs) to detect fake news and provide evidence-based explanations. Additionally, Aletheia includes two interactive components: a Discussion Hub that facilitates user dialogue around flagged content and a Stay Informed feature that surfaces recent fact-checks. Through extensive user testing, Aletheia aims to enhance users' news discernment capabilities and engagement.
