Alternatives
- Scite — Classifies how a paper was cited; this shows the citation graph.
- Google Scholar — Broader coverage and no structured API for building on.
- A publisher database — Curated and expensive, with deep coverage in specific fields.
All of these appear in our AI tools directory.
Use cases
Finding papers without a subscription
Search and discovery at no cost is the reason it is often the first stop rather than a paid alternative.
Following a citation graph
Seeing what cited a paper and what it built on is how a field gets mapped.
Pulling literature data into a project
The API lets a dataset or a review tool be built on the corpus rather than on manual collection.
Common questions about Semantic Scholar
What is Semantic Scholar?
A free academic search and discovery tool built on a large corpus of papers, with machine-extracted structure: citation graphs, related work, key concepts and author records.
Who is it for?
Researchers and students who need to find and navigate literature without a subscription, and developers who want the underlying data through its API.
Is Semantic Scholar free?
Yes. It is free to use and provides a public API, which is unusual in a category where the comparable tools are sold per seat.
What does it not do?
It does not answer a question or judge a paper. It shows you the literature and how it connects, and the assessment is still yours.
What to check first
Confirm your discipline is covered
Extraction quality varies by discipline and by how recent the work is. Confirm before treating a search as complete.
Read the paper for the claim
Extracted concepts are navigation aids. The published text is what you cite.
