March 12, 2026 . 7 minute read
Intelligent search is now a force multiplier for legal teams. Bring your firm's know-how and trusted legal guidance into one workflow, and the work gets faster, cleaner, and more defensible.
Highlights
- CoCounsel Legal and DeepJudge unify firm knowledge with Practical Law and Westlaw guidance in one AI-powered experience.
- Attorneys can surface prior work, validate legal positions, and deliver outcomes grounded in firm experience and current law.
- For corporate matters, DeepJudge finds the right deal documents while CoCounsel Legal applies market and legal guidance to support stronger negotiations.
The unseen risks created by fragmented legal knowledge
Firm intelligence lives everywhere: DMS, SharePoint, email archives, collaboration tools, and dusty shared drives. Finding the right precedent or clause often takes longer than the drafting itself.
When attorneys can't access prior work quickly, they risk missing established positions, duplicating effort, and lowering consistency. The result: slower delivery, squeezed margins, and tougher client conversations.
According to the 2026 State of the US Legal Market, firms increased technology spend by 9.7% and knowledge management by 10.5% in 2025 to fix access and reuse of institutional knowledge. But fragmentation still creates operational drag:
- Siloed or duplicated content
- Limited visibility into past work
- Governance concerns around AI tools
- Overload of unintegrated legal tech
As firms grow, these issues compound. Accuracy slips, internal standards are harder to enforce, and outcomes vary across teams.
The rising demand for AI in legal workflows
Client expectations for speed and consistency aren't slowing down. Large language models help with drafting, research, and analysis, but they need two inputs to be reliable: firm-specific work product and authoritative external content.
In our recent AI in Professional Services report, adoption is surging across core tasks: legal research (80%), document review (74%), and summarization (73%). More than half of active users report daily use.
The solution: a unified AI-powered experience
The CoCounsel Legal and DeepJudge partnership brings seamless access to internal intelligence together with trusted legal content-without data migration. DeepJudge indexes and enriches millions of documents across your DMS, SharePoint, HighQ, and network drives. Its intent-based search understands context and meaning to surface what matters.
CoCounsel Legal adds Practical Law and Westlaw guidance plus advanced AI for drafting, research, and multi-step workflows. Together, attorneys can find relevant precedents, benchmark clauses, and produce accurate first drafts that reflect firm practice and current law. Everything runs in secure, permission-aware environments.
You can access these capabilities through the CoCounsel Legal Microsoft Word add-in today, with broader access planned for the CoCounsel web platform later this year. For practical tips on optimizing Office workflows, see Office Tools.
