## Semantic Scholar

Semantic Scholar is a free, non-commercial academic search engine built by the Allen Institute for AI (Ai2). It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.

**定价与套餐:** Completely free. Semantic Scholar is operated as a non-profit academic project by the Allen Institute for AI, with no subscription tiers — accounts, search, Semantic Reader and the developer API are all available at no cost.

- **Semantic search across 240M+ papers:** Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
- **AI-generated TLDR summaries:** Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
- **Semantic Reader:** An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
- **Citation context and influence signals:** See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
- **Free developer API and Scholar's Hub:** A documented public API exposes search and metadata endpoints at no charge, while Scholar's Hub lets you follow authors, topics and citation alerts.

**优势:** Free to use with no paywall, subscription or credit limits; Very broad coverage spanning 240M+ papers in all scientific fields; Semantic ranking and AI TLDRs surface relevant work that keyword search misses; Semantic Reader adds inline citations, definitions and figures during reading

**局限:** Indexing lag means the newest preprints are not always immediately available; TLDR summaries are machine-generated and can oversimplify nuanced findings; Full text is frequently limited to what publishers or repositories expose; Not a citation manager: no built-in PDF library, BibTeX export workflow or note system
