See how Claude can use Descrybe to find legal sources, check citations, and bring back answers tied to real law.
How it works.
Connect Descrybe once. Claude gets 13 focused legal research tools backed by a corpus of 300 million legal records, authority analysis, and a legal issue knowledge graph spanning 6.5 million identified legal issues and 16.5 million case-to-issue links.
Descrybe does much of the hard legal-data work ahead of time, across millions of cases, so Claude can work from cleaned text, case summaries, legal issue structure, citation relationships, treatment signals, and source passages instead of assembling and analyzing raw legal materials every time someone asks a question.
A legal question. A citation. A case name. A quote. A docket number. A pasted brief.
Searching cases, statutes, and regulations. Running Cytator™ checks. Resolving citations. Verifying quotes. Retrieving source PDFs. Whatever the task needs, Claude reaches for the right tool, or stacks several. You can inspect the Descrybe tool calls and results to see what Claude asked for and what Descrybe returned.
Primary-law authority, verified citations, treatment signals, and source passages — ready to use.
The legal research menu Claude can reach for.
Helps Claude decide whether it has enough information to start legal research, and ask a few focused clarifying questions when key basics are missing.
Finds cases by legal issue, rule, concept, or fact pattern, with stronger authorities surfaced first.
Finds statutes, regulations, and constitutional provisions by natural-language topic, then brings back the relevant source language.
Searches judicial opinions for exact words and phrases when a quote, term of art, statutory phrase, or unusual fact pattern matters.
Turns a citation, case name, docket number, short cite, quote, or messy reference into the right case or a focused candidate list.
Reads pasted legal text and pulls out the cases being cited, grouping repeats so Claude can see which authorities are in play.
Gives Claude a concise, research-ready summary and analysis of a known case before it reasons from the opinion.
Pulls the most relevant source passages from a known case so Claude can work from the language that matters.
Brings in the case caption, court, date, available summaries, opinion inventory, and treatment overview in one place.
Checks how later cases appear to treat an authority before you rely on it, with a quick positive, negative, cautious, or neutral signal.
Finds newer cases that cite the one you are looking at, useful for updates, treatment, and follow-on authority.
Checks whether quoted language appears in a known case and points Claude to where the match appears.
Retrieves case opinion PDFs so the underlying source is easy to inspect, print, and share.
