Descrybe is a legal research and intelligence platform built on a structured corpus of U.S. primary law, offered both as a standalone workspace and as a connector for third-party AI assistants.

Key features and functions include:

Descrybe Platform
A dedicated legal research workspace combining DescrybeLM (guided research and document analysis) with the Legal Research Toolkit (direct search and verification tools), both drawing on the same underlying corpus.

DescrybeLM
Supports guided legal research, brief and document review, and multi-step research workflows, surfacing the underlying authorities considered. Research sessions can be saved and revisited, and work product can be exported to Word.

Brief and Document Review
Reviews briefs, pleadings, and other legal documents to check whether cited authorities are real and current, verify quotations against source material, and assess whether authorities support the propositions for which they are cited.

Legal Research Toolkit
Supports search by concept, keyword, case name, citation, statute, regulation, or legal issue, drawing on structured case summaries, legal issue mappings, and citation relationships in addition to opinion text.

Cytator™ and Backward Cytator™
Provides treatment intelligence at the case and legal-issue level. The Backward Cytator™ additionally shows how a given opinion treated the authorities it relied on at the time it was written.

Legal Issue Explorer
Traces how courts have addressed a legal issue across cases and jurisdictions, including related issues and patterns in how the law has developed.

Descrybe Legal Engine
Brings Descrybe's research and citation tools into supported AI environments — ChatGPT, Claude (Claude.ai, Claude Desktop, and Claude Code), Microsoft 365 Copilot, and Perplexity — offering tools such as case research, statute and regulation search, citation resolution, quote verification, and treatment review within those environments.

Descrybe Open Connector
An open-source Python SDK and set of reusable legal research workflows that allow organizations to build custom tools on the same primary-law corpus, citation and treatment intelligence, and source-verification infrastructure that power Descrybe's own platform.

One Descrybe subscription provides access across all supported environments.
