Litmaps
Litmaps helps researchers find, map, visualize, and monitor academic papers through citation networks.
Litmaps is a web-based literature discovery and review tool. Users start with a topic, keyword, DOI, author, or paper, then explore related research through citation relationships and visual maps.
Researchers, students, advisors, and research teams can organize papers, annotate maps, share findings, sync Zotero libraries, and receive alerts about new papers. The free plan has limits; advanced search, unlimited maps, and other features require Pro, while team collaboration is priced separately.
