Semantic Scholar
AI-powered academic search from Allen Institute
Expert's Tip
"The best free academic search engine, period. The TLDR summaries and citation graphs are excellent — it's what Google Scholar would be if Google actually cared about researchers."
What is Semantic Scholar?
Semantic Scholar is a free AI-powered academic search engine built by the Allen Institute for AI. It indexes 200M+ papers across all academic disciplines and uses AI to generate TLDR (too long, didn't read) one-sentence summaries for most papers. The Highly Influential Citations feature flags when a paper has had outsized impact on a field, helping you identify foundational works quickly.
For researchers and engineers tracking a fast-moving field like machine learning, Semantic Scholar is the go-to tool. The paper feed and author alerts mean you can follow specific researchers and get notified when they publish. The API is free and well-documented, popular for building research tools on top of.
Where it falls short: the AI features are more utility-focused than synthesis-focused — it doesn't answer research questions like Consensus or Elicit does. But for STEM, CS, and ML research, it's the most powerful free tool available.
