The record

Purpose: Semantic Scholar provides free, AI-driven search and discovery tools for scientific literature.
Research corpus: Its Academic Graph API page lists 214 million papers, 2.49 billion citations, and 79 million authors.
Search and discovery: Semantic Scholar uses natural language and machine learning techniques to find relevant results across academic papers.
Paper library: Signed-in users can organize saved papers into folders, bulk-export citations, and share public folders with collaborators.
Research recommendations: Research Feeds recommend papers based on papers saved in library folders and can send recommendations by email.
Ask This Paper: Ask This Paper provides AI-generated answers with supporting statements, but is available on limited papers and has been tested only on English-language papers.
Semantic Reader: Semantic Reader offers inline citation cards, paper navigation, library saving, contextual definitions, and annotation and highlighting with Hypothesis integration.
Browser extensions: Chrome and Firefox extensions let users search Semantic Scholar from highlighted text and navigate to matching paper pages.
Zotero integration: The FAQ describes saving paper information, URLs, available PDFs, and available TLDRs from Semantic Scholar pages to a Zotero library using the Zotero browser extension.
API use terms: The API license limits covered use to internal, non-commercial research or educational purposes, and directs users seeking commercial use to contact AI2 about an expanded license.
AI output limitation: Semantic Scholar says language-model-generated text in its features may contain errors that can be difficult to detect.
Mobile availability: Semantic Scholar says it has no smartphone app and that its website is designed for desktop and mobile devices.
Support: The librarian resources page directs users to the FAQ, a Contact Us form, and tutorial videos for help.
