What our research says

Clio Work

Clio Work's advantage is scale: a billion-document research corpus from the vLex acquisition combined directly with a firm's own matter files, from a legal tech company with a long operating history rather than an unproven startup. At $199/user/month as a standalone product, it costs meaningfully more than lighter legal-research tools aimed at solo practice.

Pros

Research draws on a billion-document library from Clio's vLex acquisition, not a smaller proprietary index
Combines public legal research with a firm's own matter context automatically
Now available standalone, without requiring Clio's practice-management subscription

Cons

At $199/user/month it costs more than several lighter legal-research-only tools
Full value likely depends on also using other parts of the Clio ecosystem for matter data
Standalone offering is recent (April 2026), so long-term track record outside the bundle is short

CoCounsel

CoCounsel is the safe choice for a firm already paying Thomson Reuters: research answers come with Westlaw citations, review tables trace every cell to a source, and it lives inside Word and the document-management systems lawyers already use. It is not a product you can try or price from the website — every number comes from a sales call — and the moat is the content licence, so a firm on Lexis gets far less from it.

Pros

Research grounded in Westlaw and Practical Law content with linked citations
Tabular document review scales to 10,000 documents against 100 questions
Works inside Word, Outlook and Teams and connects to iManage, NetDocuments and SharePoint
SOC 2 and ISO 42001 certifications and a stated no-training-on-customer-data policy

Cons

No public pricing and no free trial on the product pages
Value depends on an existing Thomson Reuters content subscription
Reported outcome figures come from a vendor-commissioned Forrester study
