What is Semantic Scholar AI?

Semantic Scholar is a free academic search engine developed by the Allen Institute for AI that uses machine learning to understand the meaning behind research papers rather than just matching keywords. It indexes millions of academic papers across diverse fields, making it easier for researchers to find relevant work even when they don't know the exact terminology. The tool helps academics navigate the overwhelming volume of scientific literature by using semantic understanding to improve search relevance, highlighting important papers and connecting related research. With its completely free API, developers can also integrate Semantic Scholar's capabilities into their own research tools and applications.
