What is Litmaps?

Litmaps is a web tool for literature reviews that finds papers through the citation network. You start from one or more articles, and it suggests connected work from a database of more than 270 million articles, laid out as a visual map called a Litmap. Monitor alerts send an email when new related papers appear, and the paid Pro tier adds unlimited maps, advanced search filters and Zotero Sync.

Litmaps has a free plan. Paid plans start at $10 per month, billed annually, with an academic email ($40 commercial). See every plan

Key features

Citation-network search
Start from one or more articles and Litmaps returns the most connected papers among their citations, references and co-citations, from a database of 270+ million articles.
Three search algorithms
Shared Citations & References is the default. Common Authors finds other work by the same collaborators, and Similar Text uses AI semantic analysis of titles and abstracts.
Visual literature maps
Results are shown as a Litmap of articles linked by citation. A map can be shared through a public link, with specific email addresses or as an exported image.
Monitor alerts
Monitor reruns a map's search and emails you about newly published articles. Every user can enable it; Pro users can set the frequency, algorithm and filters.
Import, export and Zotero Sync
Import BibTeX, RIS or PubMed files and export as BibTeX, RIS or CSV. Zotero Sync, a Pro feature, keeps Zotero collections and Litmaps Tags matched in both directions.
Advanced search filters
Pro users can narrow results by publication date, keyword, author, journal title, journal h-index and SJR quartile.
