Descrybe Legal Engine
ChatGPT
Available from the official Descrybe Legal Engine plugin listing, including for organization-managed access in ChatGPT Enterprise.
Legal Research Toolkit
Move from an AI answer to authority you can inspect.
Descrybe provides the research capabilities. ChatGPT provides the environment where you ask, refine, and use the result.
Check what supports the answer
Resolve citations, retrieve focused source passages, verify quoted language, and inspect the authorities behind the analysis.
Review treatment and citing cases
Research how later courts have treated an authority and find the citing decisions that matter to the issue.
Legal workflow ideas
Ask for the outcome—not just a case search.
These examples show what becomes possible when the surrounding assistant or application combines its own reading, reasoning, and work-product capabilities with focused Descrybe tools. They are ideas for use rather than separate product modes; the exact sequence and available steps depend on the host, its settings, and the context you choose to provide.
Everyday idea
Research a fact pattern
Start with a broad or fact-dependent question. ChatGPT can identify the missing jurisdiction, facts, issues, and procedural context, then research the relevant cases and non-case primary law with you.

Everyday idea
Review a brief in the chat
Upload or paste a brief and ask ChatGPT to organize a source review: extract and resolve the case references, verify quotations, inspect treatment, and find later citing decisions. For a structured review report, use Descrybe Review in the Platform.

Everyday idea
Find precedent for both sides
Describe the issue, doctrine, facts, court, and jurisdiction. ChatGPT can look for supporting and contrary cases, inspect the most useful authorities, and explain why each one may matter.

Everyday idea
Build a source-backed case note
Ask for a focused case note covering the issues, holding, reasoning, relevant passages, subsequent treatment, and later cases that discuss the decision—then open the opinion or PDF for your own review.

Advanced idea
Test a legal proposition
Give ChatGPT a legal proposition and ask it to locate authority that supports, limits, distinguishes, or contradicts it, including the opinion language and later treatment that affect the proposition’s strength.

Outline an argument
Provide the facts, objective, jurisdiction, and procedural posture. ChatGPT can research both sides, select the authorities and passages that bear on the issue, and draft an argument outline for lawyer review.

Take the opposing side
Ask ChatGPT to take the opposing side: identify vulnerable propositions, unresolved or weak citations, quotation-context problems, contrary authority, and important later cases the brief may not address.

Compare competing pleadings
Have ChatGPT compare uploaded pleadings and map the claims, defenses, admissions, denials, and disputed issues. It can then use Descrybe to research the governing law and the authorities cited in those documents.

Explain a legal document
Let ChatGPT classify and summarize an uploaded legal document, answer grounded questions about it, and use Descrybe to resolve, explain, and check the legal authorities the document relies on.
