Find primary law
Search U.S. case law, statutes, regulations, constitutions, and other covered source law with jurisdiction and authority in view.
Internal workflows with Descrybe Legal Engine
Build internal legal research tools without rebuilding the research layer.
Use the open-source Descrybe Legal Engine Python package to add structured primary-law research, citation intelligence, treatment analysis, quote verification, and source retrieval to authenticated internal apps, scripts, agents, and firm workflows that support your own legal research.

Legal Research Toolkit
Build the workflow without rebuilding legal research.
Descrybe provides the research capabilities. Open Connector 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
Build a citation and quote checker
Extract legal references from submitted text, resolve the cases, verify quoted language, and return focused source links for human review.

How it fits your work
Start with the tool you want to make.
- Give the repository to an AI coding agent and describe the legal research tool or workflow in plain language.
- Use the Python SDK and built-in agent instructions to handle setup and connect to Descrybe Legal Engine.
- Keep Descrybe as the authenticated source-law research service while your internal application controls the experience and workflow.
A Descrybe account with Legal Engine or Platform access is required to use the service.
Example starting prompt
“Build a tool that checks the citations and quoted language in a draft brief, retrieves the underlying cases, and flags authorities that need closer review.”
