Semantic Scholar

free

Free academic search and paper discovery from Allen Institute for AI with citation graphs and filters.

Semantic Scholar indexes scholarly literature across fields, surfacing influential papers, co-author networks, and citation context faster than generic web search. Students, scientists, and R&D teams use it to map a field before deep reading.

Coverage is broad but not exhaustive; preprints, paywalled PDFs, and niche venues can be missing or lagging. Features like TL;DR-style summaries are aids, not peer review substitutes.

Always open the primary source for methodological detail, and verify that automated influence scores align with your discipline’s norms.
