About This Tool
Citation Linker is designed specifically for academic researchers. In many PDF papers, citation markers (e.g., [1], [2]) are plain text, forcing readers to scroll back and forth to the reference list at the end of the document, interrupting their focus.
This tool reads PDF text locally, uses pattern recognition to match citation markers to their corresponding reference entries, and overlays clickable PDF link annotations using DOI lookups or page-jump coordinates.
It also generates an interactive citation relationship map to visually navigate the document's reference network.

Ensure your written academic papers have fully active hyperlink navigations before final submission.
Reference Map Analysis

Frequently Asked Questions
What if a reference has no DOI?
If a DOI cannot be found, the tool falls back to an internal "GoTo Page" action, allowing you to click the marker and jump directly to the reference page.
Which citation formats are supported?
It supports common numeric brackets (e.g., [1], [1-3]) and author-year citations (e.g., Author et al., 202X).
Will it modify the appearance of my PDF?
No, it injects invisible Link annotations on top of the text, preserving the original layout, fonts, and styling of your document.
