Which one is for you

Pick ResearchHub if

  • Fits if you want to fund or crowdfund a research project in the open
  • Works for reviewers who would take token payment for peer review

Look elsewhere if

  • Skip it if you want to search or summarise papers, because that is not what it does
  • Not for you if you would rather not deal with a cryptocurrency token, as rewards and bounties run on one
  • Watch out: pricing could not be verified from the pages read
  • Too light for a paper-reading workflow, as no reading or citation tools are listed

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

2.0GPAResearchHubFair3.2GPASemantic ScholarVery good
Value for money
CNo price on record: the pricing could not be verified from the pages read, so we leave it in the middle with no evidence either way.
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
CThe listing says free but marks it unverified, and the home page shows sign-up and log-in with no plan details.
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
CA funding marketplace, paid peer review and open publishing. It does not search, summarise or map the literature, so it covers a different part of the category.
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 need an account, plus a token for the rewards and bounties.
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, with no apps, API or integrations 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

ResearchHub

Funding marketplace
Links funders with researchers through preregistration, open peer review, capital commitment and linked results.
Paid peer review
Reviewers are rewarded for reviews; the page cites under 10 days average turnaround.
Open publishing
Articles published openly with no paywall, through the RH Journal.
ResearchCoin
An ERC20 token used for bounties and rewards.

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.
