Value for money
BPlus is $10 a month billed annually, so $120 a year, which is about typical here. It buys unlimited conversations, export in formats like RIS and BibTeX, and 20 MB uploads. Month by month it's $20, twice the price. Students get 30% off the annual plan.
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
BEvery search result is free, which is the main thing. Chat is capped at 3 conversations a day with 5 AI responses each, and PDF uploads stop at 3 MB. Plus has no free trial, so the free plan is your only way to try it.
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
BGood at its one trick: type, paste or upload text and get related papers from more than 250 million works, as a list and as a map grouped by research area. Chat explains methods and terms. But there's no choice of model, and uploads and conversations are deleted after 1 day.
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. There's no query to craft, because you paste what you've already written. It works in nearly 100 languages too, so a question in one can find research in another.
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
BA web app plus sidebars for Microsoft Word and Google Docs, and results export as citations for a reference manager. Universities can link it to their library collections. The site lists no mobile or desktop apps.
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.

Key features

Keenious

Search from your own text
Type a question, paste text or upload a PDF, and Keenious returns related papers. Results are retrieved from its index by meaning and keyword ranking; they are not written by a language model.
Chat about papers
Chat explains methods, statistics and terminology, including text you highlight in a paper. It runs on Google's Gemini 3.5 Flash, and there is no choice of model.
Search map
Shows each result as a dot placed by meaning, colored by research area and sized by citation count. Selecting an area filters the map and the list together.
Word and Google Docs add-ins
Keenious runs as a sidebar in Microsoft Word and Google Docs, so related research appears beside the document being written.
Search across languages
The site says Keenious can be used in nearly 100 languages, and a question in one language can find research written in another.
Bookmarks and citation export
Papers can be bookmarked, and results or bookmarks exported as citations for a reference manager; the help center points EndNote users to the RIS format.

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.
