What is Semantic Scholar?
Semantic Scholar is a free AI-powered academic search engine from the Allen Institute for AI that uses machine learning to surface the most influential papers, identify hidden connections between research, and provide citation context that shows how a paper has been received and applied. It covers 200 million+ papers across all scientific disciplines with semantic search that understands meaning and context — not just keywords. Researchers use it to find the most cited and relevant work in a field, track citations to their own papers, and receive personalized research recommendations based on their reading history. TLDR summaries generated by AI give you the core contribution of any paper in two sentences.
