Litmaps

Litmaps is a literature review tool that helps researchers find, map and monitor academic papers. A user starts from one or more seed articles, and Litmaps uses citations and references to surface the most relevant related work from a catalogue of more than 270 million papers, then draws the results as an interactive map that can be reorganized using different measures. The core features are discovery, visualization, sharing and monitoring. Discovery tools find relevant papers faster with custom filters. Maps can be annotated and shared with colleagues, students, advisors or clients. Monitoring sends automatic email alerts when new papers appear on a topic. Pro adds unlimited searches, maps and articles, advanced search, and syncing with a Zotero account. The vendor describes its algorithms as transparent and aimed at precise, comprehensive searching. It is built for academics, students and professionals doing literature reviews and keeping up with their field. The Free plan costs nothing and allows basic search with up to 20 inputs, a limited number of maps and articles per map, and monthly alerts. Pro is $10 per month, or $120 per year, with daily configurable alerts, and the vendor notes that prices may vary with country discounts. An educational license is advertised at 75 percent off and requires an academic email address. Team and Enterprise plans are available through the sales team.
