A free, private suite of Bluebook tools for law review editors and legal scholars. Built at NYU Law.
Save it once, archived forever.
An open-source Zotero plugin that automatically generates perma.cc archive links in the background as you build your research library — before the URL ever breaks.
Batch-archive every URL in your manuscript.
Drag in your .docx, select the URLs you want archived, and get back a Bluebook Rule 18.2-compliant document — with perma.cc links inserted directly into footnotes. Clean copy or Track Changes redline.
Find citation logic errors before your editor does.
Automatically audits supra, Id., signal parentheticals, hereinafter, and pincite patterns across all footnotes in your Word document. No installation. No uploads.
Both web apps parse .docx files using JSZip to extract the raw XML, then run citation logic checks entirely in your browser — no frameworks, no telemetry, no dependency on external services beyond perma.cc.
The source code for every tool is publicly available on GitHub under the AGPL v3 license. You can read exactly what runs on your machine.
// JSZip parses the .docx (a ZIP archive)
const zip = await JSZip.loadAsync(file);
const xml = await zip
.file('word/footnotes.xml')
.async('string');
// Parse footnote XML nodes in-browser
const parser = new DOMParser();
const doc = parser.parseFromString(
xml, 'text/xml'
);
const footnotes = doc
.querySelectorAll('w\\:footnote');
// No data leaves the browser
footnotes.forEach(fn => {
validateSupraChain(fn, index);
validateIdUsage(fn, prev);
validateSignals(fn);
});
