Scite.ai is a tool that mainly focuses on evaluating the reliability of scientific claims. The company uses proprietary deep learning algorithms and natural language processing techniques to analyze the text of scientific papers and extra citation contexts. Scite's large dataset is derived from the PubMed Central Open Access (PMC-OA) corpus. This is helpful to researchers because it allows them to analyze the citation context of a paper to determine if the citation supports or disputes the cited claim.
Overall, while it does not directly provide summaries of papers, it can be a useful tool for evaluating the credibility of the research you find.
