Question: I need a tool that can help me sift through a large number of research papers and provide concise answers to my questions.

If you're looking for a tool to dig through a lot of research papers and give you answers to your questions in plain language, Elicit is worth a look.

Another tool worth considering is Semantic Scholar, a free AI-powered research service that indexes more than 219 million papers across all scientific fields.
