How we grade them
| 3.2GPAIncitefulVery good | 3.4GPASemantic ScholarVery good | |
|---|---|---|
| Value for money | AFree, with no paid plans. The site says its core tools are free to use and always will be. Hard to argue with that in a category where paid plans usually start around $12 a month. | AEntirely free, with no paid plans, and built by a nonprofit. In a category where paid plans usually start around $12 a month, that's as good as value gets. |
| Free plan and trial | AEverything is free: Paper Discovery, the Literature Connector, the filters, the SQL panel and export to reference managers. One thing to know: the about page describes a single developer who covers the server costs and may seek donations or a sponsor. | AYou can search and read papers without an account. A free account adds a library, email alerts, Research Feeds and author page claiming. Nothing is held back for paying users, because there aren't any. |
| Features | BIt does citation mapping fully. Paper Discovery ranks a network by importance and similarity, the Literature Connector traces the shortest citation paths between two papers, and there's a SQL panel for power users. But keyword filters search titles only, because abstracts aren't available. | BMore than 200 million papers with filters for venue, author, type and date, a flag on the citations that really mattered, and feeds that recommend papers from what you've saved. But TLDR summaries only cover computer science, biology and medicine, and Semantic Reader is in beta and mostly for arXiv papers. |
| Ease of use | BNo App Store rating on record, so B is as high as we go. Start from a paper and you get a dashboard of tables to filter. Be patient with famous papers: their graphs can pass a million papers and take 3 to 4 minutes to build. | BNo App Store rating on record, so B is as high as we go. It works like any search engine: type, filter, read. No account is needed to get going, and a TLDR saves you opening papers that aren't for you. |
| Platforms and integrations | CA web app only, with no phone app, extension or API on the listing. You can start from a BibTeX file and export what you find to Zotero, Mendeley or another reference manager, and that's as far as it reaches. | BWeb and a browser extension, with links to Zotero and Mendeley and an Academic Graph API where most endpoints work without a key. There's no smartphone app. The FAQ says the site is designed to be used in mobile browsers. |

Who each one suits
Inciteful
- Finding the papers most similar to one you already know
- Interdisciplinary researchers tracing how two fields connect
- Citation mapping at no cost
- Power users who want to query a citation graph with SQL
Semantic Scholar
- Free literature search across all fields of science
- Keeping up with new papers through alerts and recommendation feeds
- Developers who need open scholarly data through an API
Worth knowing
Inciteful
- Keyword filters search paper titles only; the documentation says abstracts are not available.
- Graphs for heavily cited papers can pass a million papers and take 3 to 4 minutes to build.
- The about page describes a single developer who covers the server costs and may seek donations or a sponsor.
- The tool now sits at incitefulmed.com/academic, next to Inciteful Med, a separate medical research product.
Semantic Scholar
- There is no smartphone app; the FAQ says the site is designed to be used in mobile browsers.
- TLDR summaries are limited to papers in computer science and the biomedical fields.
- Semantic Reader is in beta and covers mostly arXiv papers, and Ask This Paper works on a limited set of papers.
- Unauthenticated API calls share one pool of 1,000 requests per second; an API key starts at 1 request per second.
Key features
Inciteful
- Paper Discovery
- Builds a citation network around a seed paper, then lists the most important papers by PageRank and the most similar by link-prediction measures, along with prolific authors and institutions.
- Literature Connector
- Enter two papers to get an interactive visualization of the shortest citation paths between them. It is aimed at scholars bridging two fields.
- Iterative graphs
- Add the relevant papers you find to the graph and rebuild it to narrow in on a topic. A typical depth-2 graph spans about 10,000 to 20,000 papers.
- Filters and SQL queries
- Every graph dashboard filters its tables by title keyword, citation distance and year, and a SQL query panel gives direct access to the papers and authors in the graph.
- BibTeX import and export
- Start from a BibTeX file of a paper's references, and export what you find to Zotero, Mendeley or another reference manager.
- Open data sources
- The index is built from OpenAlex, Semantic Scholar, Crossref and OpenCitations, and the site says hundreds of thousands of papers are added every month.
Semantic Scholar
- Paper search with TLDR summaries
- Searches papers with filters for venue, author, publication type and date. TLDRs are very short AI summaries, available for nearly 60 million papers in computer science, biology and medicine.
- Highly Influential Citations
- A machine-learning model flags the citations where the cited paper had a significant effect on the citing one, so a long citation list has a starting point.
- Library and Research Feeds
- Save papers into folders, share public folders and bulk export citations. Turning on a Research Feed for a folder brings paper recommendations based on its contents.
- Paper and author alerts
- Email alerts report new citations of a chosen paper, or new papers and citations for an author you follow.
- Semantic Reader
- A beta reading view for most arXiv papers, with in-line citation cards, a table of contents, AI skimming highlights and on-demand definitions of terms.
- Academic Graph API and datasets
- A REST API for papers, authors, citations, venues and recommendations, plus downloadable datasets. Most endpoints work without a key.
