How to choose AI you can trust with the work that matters

22 Oct 2026

A UK buyer’s guide to legal technology for research, drafting and contract review

Highlights

  • CoCounsel Legal reasons from Westlaw, Practical Law, and your organisation's own knowledge to deliver trustworthy answers.
  • Research, drafting, document review, and workspaces work together, with every conclusion traceable to a source you can check.
  • Evaluate legal AI by asking what it reasons from, how it handles your data, and whether it supports your precedents.

Legal professionals carry a lot. The core work comes first: research, advising on deals, managing litigation, and drafting contracts and other documents, all to the standard clients expect. Around that sits the work of managing matters and collaborating with colleagues and clients. And there’s the business of the practise itself, from marketing to client intake.

Most lawyers know technology can help with all of it. The harder part is knowing where to start, and which tools do real legal work rather than adding another screen to manage.

CoCounsel Legal is designed for exactly that. It works through the full range of legal tasks, from structuring a deal to building an argument.

What UK legal professionals need to know

Start with what the AI reasons from

Any AI can generate an answer. What it reasons from decides whether you can rely on it.

CoCounsel Legal is the only legal AI that reasons from Westlaw, Practical Law, and your organisation’s own knowledge. Westlaw and Practical Law aren’t places it sends you to do more work. Authoritative primary law and trusted practice guidance shape how it thinks through every matter.

Your own material works the same way. Prior matters, proprietary templates, and documents from your document management system are analysed alongside that content. Your standard clauses shape the draft, and your prior positions inform the legal approach.

The result is Fiduciary-Grade AI™, engineered to work at the level of a senior associate. It’s built to the standard the profession demands, with you reviewing and refining the work.

Research that does the legwork

Earlier research tools were built around search and retrieval. You wrote the query, worked through the results, and pieced the answer together yourself.

With CoCounsel Legal, you describe what you need in plain language. Whether you’re reviewing a contract, structuring a multi-jurisdictional deal, spotting risk in employment documentation, or building a litigation strategy, it develops the legal approach and works through each step. You don’t need to write special prompts or switch between tools. Research, analysis, and drafting happen from a single query.

For complex questions, Deep Research uses agentic AI, which means technology that builds a plan and carries out each step automatically. It examines your question from every angle, shows its process, and returns a full report with references from Practical Law and Westlaw. It can surface points that are easy to miss.

For cross-border work, Multinational Profile compares legal requirements across more than 100 countries in a single workflow. It draws on Westlaw (US, UK, Canada, Australia), Practical Law Global, and other vetted sources.

Drafting that reflects how you practise

Whether you’re building a brief or negotiating an agreement, CoCounsel Legal drafts directly in Microsoft Word. Describe what you need, and it builds a plan and works through each step. Your first draft arrives jurisdiction-aware, informed by Practical Law content and current market standards, with your firm’s precedents surfaced in context.

Westlaw authority, Practical Law expertise, and your firm’s knowledge do more than supply citations. They’re the foundation for the analysis and the reasoning behind the draft.

You review suggestions as in-document redlines and accept or dismiss each one. Before the document goes out, you can run a playbook comparison. That leaves your time for the substance of the matter.

Document review that scales with the matter

Tabular Analysis lets you review up to 200 documents and ask up to 100 questions, with the answers returned in a table you can filter and sort. Add documents and questions as the matter develops, without starting again. Every answer will trace back to a footnote you can follow to the source.

Workspaces that hold the matter together

Complex matters build up across documents, conversations, and people. In CoCounsel Legal, you create a workspace for each matter and upload up to 200 documents. You don’t need to choose which files are relevant. All of it becomes part of how CoCounsel Legal reasons. When you return to a matter, the context is already there, so you pick up where you left off.

Integrations and security

CoCounsel Legal fits into the tools you already use. It connects to files in iManage and SharePoint, and it works within Microsoft 365, so your own matters ground the answers you get.

Your data stays your data. It’s secure, private, and never used to train the underlying models. And because the platform is designed to evolve, its capabilities will keep advancing with the technology and with the demands on your practice.

Not every legal AI works the same way. These questions help you see the difference.

  • What does it reason from, and can it show you?
  • Can you trace every conclusion back to a source you can open?
  • Does it work with your firm’s precedents and playbooks, as well as public sources?
  • Does it support both litigation and transactional work?
  • What happens to your data?

The right solution gives you work you can trust and time to apply your judgement, and the questions above help you find it.

Where to go from here

How lawyers work is changing quickly, even though the work itself isn’t. Matters still turn on sound research, careful drafting, and good judgement, and CoCounsel Legal helps with the groundwork by showing its reasoning and linking every source so you can check it yourself.
