Casetext

Casetext was one of the best-known AI legal tech companies, and today its technology lives on through CoCounsel from Thomson Reuters. If you are looking up Casetext, what you are really looking for now is an AI-powered legal assistant designed to help lawyers research cases, review documents, draft faster, and handle complex legal work with more confidence.

That makes Casetext especially interesting for law firms, in-house legal teams, and other legal professionals who want more than a general AI chatbot. Instead of giving broad answers, it is built around legal workflows and trusted legal content.

What is Casetext?

Casetext was founded in 2013 as a legal technology company focused on helping legal professionals work more efficiently. In 2023, Thomson Reuters announced its acquisition of Casetext, including its AI legal assistant CoCounsel. Today, the Casetext brand is largely associated with CoCounsel and related Thomson Reuters legal AI products.

In simple terms, Casetext is best understood as the legal AI platform behind CoCounsel. The tool is designed to support legal research, document analysis, drafting, deposition preparation, and contract review using generative AI combined with professional legal content.

Who is it for?

Casetext is built mainly for legal professionals. That includes solo attorneys, law firms, litigation teams, corporate legal departments, and legal operations professionals. It is not a general-purpose writing tool for casual users. Its strongest value comes from legal work that requires accuracy, speed, and access to trusted sources.

If your daily work includes reviewing long documents, checking legal authority, preparing research memos, or drafting agreements, this type of tool can save a meaningful amount of time.

Main features

One of the biggest strengths of Casetext, now delivered through CoCounsel, is that it combines several legal tasks in one system instead of focusing on only one use case.

Its main features include AI-assisted legal research, document review, document summarization, contract analysis, drafting support, and workflow automation for complex legal tasks. Thomson Reuters also positions CoCounsel as a unified experience that can work across Westlaw, Practical Law, Microsoft 365, and document management systems.

For users, that means you can ask legal questions in plain language, analyze uploaded files, pull out key points from large document sets, and speed up first drafts without switching between too many tools.

Common use cases

Casetext is commonly used for legal research, creating research summaries, reviewing contracts, checking litigation documents, preparing for depositions, and analyzing large batches of legal files. It is also useful when a legal team needs faster first-pass analysis before a human expert does final review.

Another practical use case is drafting support. Legal professionals can use it to modify language, summarize clauses, compare documents, and accelerate document creation inside familiar workflows.

How to use Casetext

Using Casetext today usually means using CoCounsel through Thomson Reuters.

1. Access the platform

Start by requesting a demo, trial, or plan through Thomson Reuters. Because this is a professional legal product, access is generally organized through sales or account-based plans rather than a simple consumer-style sign-up flow.

2. Choose your task

After getting access, choose the type of work you want help with. For example, you might run legal research, upload a contract for analysis, summarize a long document, or start a drafting workflow.

3. Enter a prompt or upload files

You can describe your question in natural language or upload documents for review. This is useful for tasks like spotting key clauses, summarizing evidence, identifying issues, or generating a research-based response.

4. Review the output carefully

Like any AI legal tool, Casetext should be used to assist professional work, not replace legal judgment. Review citations, confirm reasoning, and check the final output before relying on it in client-facing or court-related work.

5. Use integrations when available

For teams already using Microsoft Word, Outlook, Teams, SharePoint, OneDrive, iManage, NetDocuments, or other document systems, integrations can make the workflow smoother. This helps legal professionals work inside tools they already use instead of copying content back and forth.

Pricing

Casetext pricing is not presented as simple public self-serve pricing in the way many consumer AI tools are. Thomson Reuters offers CoCounsel and related legal products through plan-based and sales-led pricing. In practice, this places Casetext in the paid category.

There may be a free demo, and some CoCounsel pages mention requesting a free trial, but availability can depend on the product version, organization type, and sales process. If pricing is important for your team, the best path is to contact Thomson Reuters directly for current plan details.

Supported platforms

Casetext is primarily available as a web-based professional platform through Thomson Reuters products. It also supports Microsoft 365-based workflows, including Word, Outlook, and Teams in certain product versions. Depending on your plan, it may also connect with document management systems and cloud repositories.

This makes it a better fit for desktop and browser-based legal work than for casual mobile use.

Key benefits

The biggest benefit of Casetext is speed without losing legal context. Instead of using a general chatbot that may not understand legal workflows well, users get a tool designed for professional legal tasks.

It can help teams save time on research, reduce manual document review, summarize dense material faster, and improve drafting efficiency. It is especially valuable for firms and legal departments that want AI support grounded in trusted legal content and more structured workflows.

Things to keep in mind

Casetext is a specialized legal AI product, so it makes the most sense for professionals rather than general users. It is also best used as an assistant, not a substitute for legal expertise. The strongest results come when experienced legal professionals use it to speed up research and drafting while still applying human review.

It is also worth noting that if you search for Casetext today, you may find older references to the original standalone platform. In current practice, the most relevant official product experience is CoCounsel from Thomson Reuters.

Final thoughts

Casetext helped shape the legal AI category, and its technology now continues through CoCounsel under Thomson Reuters. For lawyers and legal teams that want AI support for research, drafting, and document analysis, it remains one of the most relevant names to know.

If you want a legal-specific AI assistant rather than a general chatbot, Casetext is worth exploring through the current CoCounsel offering. Its biggest advantage is clear: it is built for real legal work, not just generic text generation.
