The Search4Ukraine project took the first place. Its authors have designed a web application to assist Ukrainian refugees in finding credible information on their country's situation from anywhere in the world. The mechanism optimizes the Google search engine in two ways: it seamlessly translates web search requests into the language of the current country of residence and back into Ukrainian, and it also optimizes the Google search API to prioritize information provided by local governments and non-profit organizations.

The creators of Damage Map developed a fully functional website – which is also mobile-friendly – that allows users to report the degree of destruction of public buildings and residential facilities, and thus determine whether or not they are still functioning. The application's aim is to let citizens quickly and effectively share information and make decisions regarding, for example, choosing the hospital to go to. Authors: Maciej Kutyła, Tymoteusz Zapała

The authors of Disinfo Fighter have developed a tool to fight disinformation. Fake news, which can be easily replicated via Twitter, was deemed the greatest threat by the authors. In response to this threat, students have developed a Google Chrome extension that detects false and propagandist information in tweets.
