This tool is designed to be used with scientific research articles, rather than media stories or other reports about research. You need to read the original research so that you can appraise it for yourself instead of relying on someone else's interpretation. People use various names to refer to scientific research articles, including articles, papers, and manuscripts.
If you do not have a specific research paper in mind, you can search for research on the topic that you are interested in by using a search engine designed for finding scientific articles, such as Google Scholar or Jurn.
