See which papers get cited together, and which sit at the centre.
What this tool does
This tool turns co-citation pairs into a network graph. You paste one pair per line, meaning two papers cited together, and the tool draws each paper as a node and each pair as a link, arranged in a circle. Papers that appear in many pairs sit at the visual centre of attention, because many links touch them, which is a quick way to spot the core literature of a topic.
It works fully in your browser. Nothing is uploaded to a server, and you do not need an account. Paste your text, press the button, and read the result on the same page. That makes it useful for students, researchers, and anyone who has to get through a long paper quickly without losing the important parts.
How to use it
List your pairs one per line in the format first paper, vertical bar, second paper, using short labels such as author and year. Press the draw button and look for nodes with many links: those are the papers co-cited with many others. Then read those central papers first, because the field itself keeps returning to them.
Worked example
Three pairs linking Smith 2020 with Lee 2021, Smith 2020 with Garcia 2022, and Lee 2021 with Garcia 2022 draw a triangle of three nodes with three links. Every paper is equally connected here, which tells you this tiny set is a tight cluster rather than a field with a centre and a periphery. With twenty pairs, a centre usually emerges clearly.
How to read the results
The output is a network diagram with labelled nodes and links, plus counts of nodes and edges. Node labels are shortened to ten characters to keep the diagram readable, so use short labels in your paste. The diagram is a picture of your pairs, not a statistical analysis: it shows connections, not strengths.
Do not treat the output as a final answer. It is a starting point for your own reading. Skim the highlighted parts first, then read the full passage around anything that matters for your work. A tool can point at the likely important sentences, but only you can judge whether they are actually important for your question.
Honest limits
A circle layout shows connections but not clusters, distances, or importance in any rigorous sense: position around the circle is arbitrary, and a paper can look central simply because you entered many pairs for it. The tool does not fetch citation data, so every pair must come from your own reading. For real network analysis, export your pairs to a dedicated network tool.
This tool does not use artificial intelligence, and it does not understand your paper the way a human reader does. It follows fixed rules that you can inspect in the results. That is a strength when you want transparent, repeatable results, and a weakness when a passage needs real understanding, context, or judgement.
Tips for best results
Paste clean text. Remove page headers, footers, and reference lists before you paste, because they add noise to word counts and sentence scores. Work on one section at a time for long papers, and keep your original file open beside the tool so you can check anything surprising against the source. If you use the result in your own writing, always cite the original paper, never the tool output.
Frequently asked questions
Is it free? Yes. The tool is free to use online, with no sign-up and no download.
Is my text stored anywhere? No. Everything runs in your browser tab. Closing the tab removes your pasted text.
Can I trust the output completely? No tool of this kind should be trusted blindly. Use it to speed up reading and checking, then verify the important claims yourself in the original text.
