Semantic Scholar: Free Academic Search Engine with AI and Citations
Semantic Scholar is a free academic search engine powered by artificial intelligence from the Allen Institute for AI (AI2). This tool centralizes and analyzes scientific literature to help discover articles, authors, and relevant research lines with greater precision than classic keyword searches. In this Semantic Scholar review, we explain why it can be the best AI tool for research when an SME, consultancy, or small team needs to explore scientific evidence to make decisions, validate proposals, or prepare technical content.
AgentAya Verdict
This tool stands out for its ability to “understand” scientific articles: it generates automatic one-sentence summaries (TLDR), offers augmented reading with Semantic Reader, and recommends new content through Research Feeds.
It’s ideal for SMEs that prepare reports, due diligence analyses, or technical content in regulated sectors and need to maintain citation traceability. Its limitations include an interface and corpus optimized for English, the absence of a native mobile application, and a reduced integration ecosystem. Even so, it effectively fulfills the tool’s main purpose: facilitating the search, reading, and understanding of scientific literature with the help of artificial intelligence.
Recommendation: excellent as an AI-powered academic search engine and augmented reader for teams working in English and not requiring deep enterprise integrations.

AgentAya Overall Score: ⭐⭐⭐ 3.4 / 5
Solid for SMEs requiring to find, evaluate, and cite scientific evidence quickly.
Ideal for:
- Founders and SMEs creating evidence-based reports.
- Agencies or consultancies needing quick maps of authors, topics, and citations.
- Technical content teams requiring summaries and contextual reading.
Not ideal for:
- Organizations needing solid coverage or support in languages other than English.
- Companies seeking integrations with CRM/ERP or private databases.
- Users requiring a complete mobile app.
Main Features
- AI-powered academic search: Prioritizes semantic relevance and highlights key paper contributions.
- One-sentence TLDR: Generates automatic summaries to decide which papers to delve into.
- Semantic Reader: Augmented reading with contextual citation cards and highlighted sections.
- Research Feeds: Personalized recommendations trained with user preferences.
- Bibliography and exports: BibTeX/RIS formats compatible with Zotero, Mendeley, and EndNote.
- Public API: Access to the academic graph (authors, citations, venues) and open datasets.
AI Functions
Semantic Scholar’s AI combines natural language processing and recommendation models to:
- Generate TLDR in results.
- Enrich reading with context in Semantic Reader.
- Detect relationships between topics, authors, and citations.
- Personalize Research Feeds according to reading habits.
Its “intelligence” lies in semantic understanding of full text and adaptive recommendation based on embeddings.
Integrations
Operates with bibliographic managers through export or browser extensions. Has an official REST API with search endpoints, authors, citations, and datasets (Semantic Scholar Academic Graph). Doesn’t offer direct connectors with CRMs or other enterprise systems.
Security and Data Compliance
- User data ownership: Managed by the Allen Institute for AI according to its privacy policy.
- Data use: Public content may be used for research and model improvement; user information is treated according to current policy (February 2025).
- Encryption: AI2 declares standard security measures (TLS, HTTPS).
- Certifications: No specific ISO or SOC certifications indicated.
For corporate environments, review AI2’s Terms and Privacy Policy before use.
Language – Customer Support and Interface
Interface, documentation, and support mainly in English. Assistance through help center, contact form, and academic community. No formal support offered in other languages.
AI Language
AI functions (TLDR, Reader, recommendations) are optimized for articles in English. Can index papers in other languages, but summary precision and classification is lower.
Mobile Access
No official mobile application exists. The website responds correctly in mobile browsers, but the complete augmented reading and library management experience is smoother on desktop.
Support, Onboarding Process, and Account Management
Self-assisted onboarding process through FAQs and tutorials. Active researcher community. No guided onboarding or dedicated support for businesses.
Ease of Use / UX
Minimalist search-engine-style interface, with clear filters and well-structured article pages. Direct access to TLDR, Semantic Reader, and citation options. An SME can obtain immediate value if they organize thematic libraries and activate Research Feeds.
Pricing and Plans
Semantic Scholar is completely free. Its public API is also free with rate limitation (1 RPS with private key).
Case Study
A health consultancy needed to map evidence on digital therapies. With Semantic Scholar, they created a thematic library, activated Research Feeds, and used TLDR to filter 300+ articles to 40 relevant ones. The report was completed in two days, reducing review time by 60%.
