AI4Debunk aims to revolutionize the fight against disinformation and support trustworthy online activity. Through the development of AI-powered human-centered tools, this EU project is committed to safeguarding democratic values and fostering a more informed and resilient society in response to the challenges posed by the digital age. AI4Debunk will develop four AI-powered human-centered interfaces built upon a “debunking” API: a web plug-in, a collaborative platform, a smartphone app, and an AR interface. To develop such an API, AI4Debunk will focus on two peculiar disinformation topics: the war in Ukraine and disinformation related to climate change.
