#1Models.dev 记录了 200,451 月访问量,月度环比增长为 -3.9%,定价为免费。Semantic Scholar 记录了 8,198,672 月访问量,增长率为 +5.8%,定价为免费。

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.

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.
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
专项更强Broader real-time web search capabilities with academic filters, but less specialized for deep bibliographic citation analysis than Semantic Scholar.
#1专项更强提供先进的智能引用(Smart Citations)功能以显示论文间的支持或争议关系,但整体索引规模较小。

专项更强Includes model pricing trackers and developer news alongside tools directories, but less focused on raw API specs.
专项更强Paper Digest is an AI research platform that summarizes literature, generates literature reviews with citations, and delivers daily digests of new papers across arXiv, PubMed, bioRxiv and major conferences. Launched in 2018 and used by millions of researchers, it combines a citation-backed review engine that avoids inventing results with tools for reading PDFs, writing, question answering, claim verification and topic tracking.


专项更强Organizes research fields into visual concept maps for exploratory discovery, but lacks granular paper recommendation feeds.


专项更强Catalogues and compares AI infrastructure tools and services across categories, but lacks deep per-token pricing tables.
