Bottom line up front
Yes, Casetext CoCounsel is worth it for solo attorneys who do meaningful legal research. It is the most capable AI legal research tool available to practitioners without enterprise budgets, and it does something that general AI tools genuinely cannot: it understands legal context, cites real cases, and produces research that holds up to professional scrutiny.
For attorneys billing $200 or more per hour, Casetext pays for itself the first time it cuts a two-hour research session to 45 minutes. For attorneys doing frequent research, the math gets even more compelling quickly.
Always verify citations: Like all AI legal research tools, Casetext can produce errors. Every citation must be verified in primary sources before relying on it in any professional capacity. This is not unique to Casetext — it is the professional standard that applies to all research.
Background: Casetext was acquired by Thomson Reuters in 2023. CoCounsel is now part of the Thomson Reuters legal technology portfolio, which provides additional stability and resources behind the product. Pricing and features verified as of March 2026.
What is Casetext CoCounsel?
Casetext CoCounsel is an AI legal assistant built specifically for legal professionals. Unlike general AI tools that were adapted for legal use after the fact, CoCounsel was trained on legal data and designed around legal workflows from the ground up.
The core product includes AI-powered legal research, document review, deposition preparation, contract analysis, and legal memo drafting. It connects to a comprehensive legal database and understands jurisdiction-specific nuances that general AI tools completely miss.
Key capabilities
AI legal research
Ask a legal research question in plain English. CoCounsel searches case law, statutes, and secondary sources, then delivers a researched answer with cited sources you can verify.
Document review
Upload contracts, briefs, or discovery documents. Ask specific questions about the content. CoCounsel reads and analyzes documents that would take hours to review manually.
Legal memo drafting
Generate research memos from a research question. CoCounsel organizes findings, structures the analysis, and produces a drafted memo you can edit and refine.
Deposition prep
Generate deposition question outlines from case documents. Surfaces relevant facts and potential inconsistencies worth exploring in examination.
Contract analysis
Review contracts for specific provisions, risk factors, or clause comparisons. Particularly useful for solo attorneys reviewing unfamiliar contract types quickly.
Jurisdiction awareness
CoCounsel understands that a research question in California and the same question in Texas may yield different answers. It research within specified jurisdictions accurately.

How Casetext scores
Is Casetext worth $100 per month for a solo attorney?
Our honest answer: yes, for most solo attorneys
The $100 per month price point is significant for a solo practice. But the calculation is straightforward: if Casetext saves you one hour of research time per month at a billing rate of $150 per hour, it has already paid for itself with $50 left over.
Solo attorneys who do regular legal research, handle document-intensive matters, or frequently encounter unfamiliar areas of law will see returns many times the monthly cost. Those who rarely do substantive research and primarily handle transactional matters with established templates may find less immediate value.

Frequently asked questions
How does Casetext compare to using ChatGPT for legal research?
They serve different purposes. ChatGPT is useful for drafting and summarizing but cannot reliably cite case law and should never be trusted as a primary research source. Casetext was purpose-built for legal research, trained on legal data, and cites real, verifiable sources. For anything requiring citation accuracy, Casetext is the appropriate tool.
Does Casetext cover all 50 states?
Yes. CoCounsel handles jurisdiction-specific research across all 50 states and federal jurisdictions. You specify the jurisdiction in your research question and the tool searches within that jurisdiction's case law and statutes.
Is Casetext appropriate for a solo attorney doing primarily transactional work?
It depends on the volume and complexity of the transactions. For attorneys regularly reviewing unfamiliar contract types or researching state-specific requirements, the document review and research capabilities provide meaningful value. For attorneys handling highly repetitive transactional work with established templates, the ROI case is weaker.
What happened when Thomson Reuters acquired Casetext?
The acquisition in 2023 has been broadly positive for users. Thomson Reuters' legal database access strengthened CoCounsel's research capabilities. The product has continued to develop, pricing has remained accessible for solo practitioners, and the institutional backing provides stability that early-stage legal AI tools often lack.
