Google Scholar is a free academic search engine that searches scholarly material from many organisations and websites. It can be useful alongside LibrarySearch for following citations, locating a particular paper or author, and finding openly available copies of publications.
Standard Google Scholar presents search results and links rather than generating an answer to your research question. Google also provides Scholar Labs, an experimental AI-powered search feature that analyses research questions and generates explanations of how selected papers relate to them. Whichever version you use, you still need to open, read and evaluate the original sources.
