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

Harvey

Harvey is the enterprise choice for large firms and legal departments that want one vendor to cover research, review, drafting and now intake and regulatory tracking, with the security paperwork and regional hosting those buyers require. It is not something a solo practitioner or a small firm can sign up for, and the lack of any public price means the comparison with CoCounsel or Legora happens in a sales cycle, not on a pricing page.

Pros

Covers the whole legal workflow, from intake to agents to document vaults, rather than one point task
Regional instances for the US, EU and Australia address data-residency objections up front
Cited answers tied back to source documents and legal content, which is the minimum for legal use
Well capitalised: $550M raised at a $15.5B valuation in September 2026, so vendor risk is low

Cons

No public pricing, trial or self-serve sign-up; every evaluation runs through sales
Built for enterprise procurement, so mid-size and small firms pay for scale they do not use
No public API or developer surface found, so it does not slot into a custom stack
Rapid module expansion means parts of the platform are months old and lightly proven
