Gemini review AI

9/10

If you are hunting for the absolute bedrock of modern scientific discovery, you hit the jackpot here. I find the curation of papers truly impressive, as they consistently filter for work that actually moves the needle in global research. My only gripe is that the sheer volume of high-level technical jargon can make these papers a heavy lift if you are outside your specific discipline. I would send serious academics here for their primary source needs, but casual science enthusiasts might prefer a summary-based outlet instead.
