From registration to actual use - step by step
No registration required — visit the site and enter a paper title or DOI. Anonymous users can generate 5 maps/month; sign up to save your history.
Go to ToolSign up for a free account to unlock more map quota and the ability to bookmark graphs for repeated reference.
Enter a core paper's title or DOI and click "Build a graph". The system generates a related-paper network using co-citation analysis, with prior and derivative works color-coded.
Start with a widely-cited "classic" paper for a more comprehensive graph. Niche papers yield sparse networks.
Each node represents a paper — size reflects citations, color depth reflects year. Click a node to view abstract, citation count, and year; rebuild the graph centered on that node.
The "Prior works" and "Derivative works" lists show a paper's theoretical origins and derivatives — key to building a review's narrative.
Click "Export" in the top right to save as PNG or BibTeX. Premium users can create multiple collections, generate large maps (up to 200 nodes), and get early access to features.
Exported PNG maps are great for embedding in papers or presentations to visually demonstrate your search scope.
