BluebookGenie formats legal citations with jurisdiction-specific rules for every federal and state court. It knows which jurisdictions require canonical Bluebook formatting and which require their own style — California’s Style Manual, Texas’s Greenbook, New York’s Official Reports Style, Michigan’s Uniform System, and the 15 states that have adopted public domain citation systems (Illinois, Wisconsin, Ohio, Colorado, and others). It resolves cases against CourtListener’s database of millions of opinions and generates properly formatted citations for any jurisdiction. If BluebookGenie can’t find your case, it lets you know — so you can verify the citation isn’t a hallucination.

Andrew Dietderich, Partner, Sullivan & Cromwell — New York Times, April 21, 2026The Bluebook is the most complex citation system in existence. It is not template-compatible — the same case can be cited differently depending on where it appears, how it's been cited before, and what court you're in.
Id., supra, infra, hereinafter — all context-dependent. BluebookGenie handles them automatically across your entire document.
Federal vs. state, circuit-specific abbreviations, historical court names. BluebookGenie knows the rules for every jurisdiction.
Affirmed, reversed, cert. denied, overruled — citation signals that change over time as cases move through the system.
