Which one is for you
Pick Scinapse if
- Fits if you judge papers by citations within your own field
- Works for people hunting for experts on a topic
Look elsewhere if
- Pricey if you want the network maps or saved mini-reviews, which start at $36 a month
- Tight if you stay free: AI mini-reviews, author analytics and advanced filters are paid
- Watch out: AI Smart Query is capped at 5 credits per 4 hours on Pro
- Skip it if you want an app, as it is web only
Pick Semantic Scholar if
- Fits if you want free literature search across every field of science
- Works for developers who need open scholarly data through an API
Look elsewhere if
- Not for you if you want to question any paper, since Ask This Paper works on a limited set of them
- Tight if you work outside computer science and the biomedical fields, where papers get no TLDR
- Skip it if you want a phone app, as there isn't one and you use the mobile site
- Watch out: Semantic Reader is still a beta and mostly covers arXiv papers
- Tight if you build on the API: a key starts at 1 request per second, and keyless calls share one pool
How we grade them
| 1.8GPAScinapseWeak | 3.2GPASemantic ScholarVery good | |
|---|---|---|
| Value for money | DBasic is $23 a month billed yearly, which is where the dearest tenth of the category starts ($23). Network maps and saved AI reviews need Pro at $36, and Max is $52. | AEntirely free, with no paid plans, built by the nonprofit Ai2. Paid plans in this category start at $10 and mostly land around $12 a month, and this costs nothing. |
| Free plan and trial | CA free plan with search, collections and citation export, plus a 7-day Pro trial. AI features, advanced filters and author analytics sit behind paid plans. | AYou can search and read papers without an account. A free account adds a library, email alerts, Research Feeds and author page claiming. There are no paid plans, so nothing is held back. The one cap is on API calls: a key starts at 1 request per second. |
| Features | CField-specific impact, expert finder, journal analytics and AI mini-reviews. The listing shows network maps and AI Smart Query only on Pro or Max, and Smart Query is rate limited every 4 hours. | CMore than 200 million papers with filters for venue, author, type and date, a flag on highly influential citations, and feeds that recommend from what you've saved. The gaps are on its own pages: TLDRs only cover computer science, biology and medicine, and Semantic Reader is a beta, mostly arXiv. |
| Ease of use | CNo store rating on record, and you work through filters, collections and citation analyses to get value from it. | BNo store rating on record, so B is the ceiling. There's nothing to set up: type a search, filter and read, with no account needed to start. |
| Platforms and integrations | CWeb only: no mobile or desktop app and no API are listed. | BWeb and a browser extension, with links to Zotero, Mendeley and LibKey and an Academic Graph API where most endpoints work without a key. There's no phone app: the FAQ says to use the site in a mobile browser. |

Key features
Scinapse
- Field-specific impact
- Measures citation impact inside the set of papers for a topic instead of across all research.
- AI mini-reviews
- Generates a short review of a field; Basic and above can generate them, Pro and above can save them.
- Expert Finder
- Finds researchers by keyword and filters by career and affiliation; full search needs a paid plan.
- Network map
- Shows how papers and authors connect through citations. Pro and Max only.
- Journal analytics
- Shows journal performance and trending topics, aimed at journal editors and authors choosing where to publish.
- AI Smart Query
- Turns a plain description of a research question into a query. Credits are shared with Expert Finder and Research Intelligence.
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.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
