Traditional digital voting assistants are online survey tools that help voters make a voting choice. Nevertheless, many young adults do not vote. Therefore, a study was conducted, in which two new types of digital voting assistants for young adults were compared: a voting assistant chatbot versus a voting assistant avatar. A small-scale experiment (N = 30) was used to investigate the influence of these voting assistants on the political knowledge and voting intention of young adults shortly before the election for the European Parliament in June 2024. In addition, the voting assistants were evaluated for user-friendliness, entertainment value and the extent to which young adults trusted the voting assistants. The results show that after interacting with both voting assistants, participants have more political knowledge and a higher, general voting intention. The increase in political knowledge is greater for participants with less political interest. In line with expectations, participants find the chatbot more user-friendly than the avatar. Participants also find the chatbot more entertaining and have more trust in the chatbot than in the avatar. This research shows that new forms of voting assistants may increase the political knowledge and voting intention of young adults. In this way, this research provides early insights into an important area of research, namely the potential contribution of these tools to an increase of the chance that young adults will actually cast their vote, and through this contribute to the strength and representativeness of the European Parliament.
