Semantic Scholar - A free, AI-powered research tool for scientific literature

Love this tool and can definitely vouch for it! They also have an API and powering some new upcoming products like https://consensus.app/search/ which you may be interested in. Personally, I find consensus to be a bit more useful and the AI summaries are handy.

I'm also working on a similar tool that combines searching, reading and citation management of articles in a single platform. Here's the link if you are interested: https://tryhexle.vercel.app/
