The main purpose of Quackcheck is to help users determine if the article's sources are properly cited and if those sources can be considered trustworthy. This allows readers to make more informed decisions and avoid being misinformed by articles lacking proper justification or referencing. With Quackcheck, users can easily evaluate the credibility of sources and gain a deeper understanding of the information they encounter online.
