Casetext's core product, CoCounsel, functions as an AI assistant that legal professionals interact with by assigning specific tasks rather than typing open-ended prompts. Users select a skill, such as document review, legal research memo, deposition preparation, or contract review, upload relevant files or describe a legal question, and CoCounsel returns organized output with citations back to source documents or case law. This task-based structure is designed to fit into existing workflows like discovery review or memo drafting rather than requiring lawyers to learn prompt engineering.
The platform highlights several named skills as distinguishing features: Document Review for flagging responsive or privileged documents across large sets, Legal Research Memo for generating research summaries with citations, Deposition Preparation for building outlines from case documents, Contract Review for identifying deviations from playbooks or missing clauses, and Contract Policy Compliance for checking documents against internal policies. Casetext also integrates with legal databases for case law and statutes, and it emphasizes that every output includes citations that can be checked against source material to reduce reliance on unverified AI-generated text.
Casetext is aimed at law firms, corporate legal departments, and individual attorneys who handle research-intensive or document-heavy matters such as litigation, contract review, and compliance work. Pricing is not publicly listed on a self-serve basis; prospective customers contact Casetext for quotes, which typically depend on firm size and usage volume. It competes with other AI legal research and drafting tools such as Harvey, Lexis+ AI, and Westlaw's AI-assisted research products.
Casetext operates as a web-based platform accessed through a browser, with document upload and review handled within its interface. It does not publish a public API for third-party integration, and it is positioned primarily as an end-user application for legal teams rather than a developer platform.
An AI-powered brief analysis tool, recognized with the World Economic Forum's Technology Pioneer award, that helped establish Casetext's legal AI innovation prior to CoCounsel.
Identifies relevant topics to address in a deposition and drafts targeted questions for each, producing a refined deposition outline based on user-specified areas of interest.
Lets users converse with CoCounsel in plain English to delegate substantive legal tasks, powered by OpenAI's GPT-4 large language model that has passed the Uniform Bar Exam.
Generates comprehensive legal research memos with citations in response to natural-language legal questions, such as researching whether protected employee activities lose protection under Title VII.

Reviews uploaded contracts against a stated company policy, flags noncompliant clauses (e.g., arbitration exemptions), and recommends redlines downloadable in Microsoft Word.
Drafts correspondence tailored to different audiences, including clients, judges, opposing counsel, and third parties.
Searches an extensive, up-to-date collection of caselaw and statutes and cites sources in its outputs so results can be efficiently verified by attorneys.
Rapidly analyzes large sets of documents for use cases like due diligence, e-discovery, and internal investigations, quickly identifying key documents and extracting critical information.
Provides a menu of purpose-built application "skills" (e.g., legal research, document review, contract analysis) that users can launch directly from the chat interface, with recently used skills surfaced automatically.
Integrates CoCounsel's AI capabilities across Thomson Reuters products including Westlaw Precision, Practical Law, Document Intelligence, and HighQ, while also remaining available as a standalone product.
Encrypts all content processed through the platform end-to-end and ensures client materials and data are never stored or used to train the underlying AI models.
Casetext (now part of Thomson Reuters as CoCounsel) does not publish self-serve pricing. It is sold to law firms and legal departments on a custom, sales-led basis depending on firm size, seat count, and module selection (legal research, AI drafting/review, etc.); prospective buyers must contact Thomson Reuters/CoCounsel sales for a quote.
