What Litmaps does
Litmaps is a literature-discovery platform that maps citation relationships, recommends connected papers, organizes review projects, syncs selected reference tools, and alerts users to new work.
Litmaps makes the citation graph visible and usable. A map can begin with one paper or an imported collection, then expand through related references and citations. Users can organize papers, alter the visualization, share maps, monitor topics, and on paid plans use advanced search, unlimited maps, and Zotero synchronization.
The free tier supports basic search and limited maps and article counts. The live pricing page shows an education-oriented Pro price from $10 monthly with annual billing and notes parity or academic discounts; commercial and Team terms differ and may require checkout or sales contact. Researchers should verify limits for maps, alerts, collaboration, and institutional use.
Citation links favor fields and publication types with strong metadata and do not detect every relevant paper, unpublished result, retraction, or methodological flaw. Litmaps' June 2026 privacy policy says it stores saved research content and samples masked session recordings and uses listed subprocessors. Do not treat a map as a systematic review by itself; combine databases, record queries, screen papers, verify retractions, and assess study quality.
How Litmaps works
A researcher searches for or imports trusted seed papers, PDFs, identifiers, or reference-manager records. Litmaps places articles as nodes connected by citations and references, then ranks related work from the broader citation network. Users add relevant results, tag and annotate the map, adjust filters, and configure alerts for new papers. The system discovers connections rather than proving relevance or quality, so people must read originals, verify metadata, search complementary databases, and document inclusion decisions.
How to set up Litmaps
Write the review question
Define scope, populations, concepts, dates, languages, publication types, inclusion rules, and complementary databases before mapping.
Select diverse seed papers
Start from verified landmark, recent, and methodologically different papers rather than a single favored author or cluster.
Build and tag the map
Explore citations and references, save plausible articles, tag reasons for inclusion, and record searches and dates.
Validate outside Litmaps
Read original papers, check identifiers and retractions, assess methods, and search subject databases and grey literature for missing work.
Monitor and collaborate carefully
Configure alerts, sync approved libraries, define team ownership, protect sensitive notes, and periodically revisit the map's blind spots.
Litmaps FAQs
Is Litmaps an AI answer engine?
Its core workflow is citation-network search, recommendation, mapping, and monitoring, not an authoritative generated answer to a research question.
Is there a free plan?
Yes. Free includes basic search and limited maps and article counts; current limits differ between displayed pricing variants, so verify in-app.
How much is Pro?
The live page shows education pricing from $10 per month with annual billing and country or academic discounts. Commercial pricing can differ.
Can Litmaps replace a systematic-review search?
No. Citation discovery can miss isolated, new, non-indexed, or differently worded work. Use documented searches in appropriate subject databases too.
What research data does Litmaps store?
Its privacy policy lists saved papers, maps, collections, annotations, notes, account and usage data, and sampled masked session recordings.
