Document analysis and review

Tabular Analysis

Automate large-scale document review to answer up to 100 questions across as many as 10,000 documents at once. Results land in a single interactive table — filterable, sortable, and footnoted directly to the source — so you can verify any answer without reopening the original file.

Litigation Document Analyzer

Upload complaints, discovery, filings, or contracts and receive a structured analysis — key facts extracted, issues flagged, and every finding linked back to its exact source document and page. The same rigor applies whether you're reviewing one document or thousands.

Legal drafting

Create work product that reflects how your organization practices law. Draft step by step using trusted guidance from Westlaw, Practical Law, and your internal knowledge, with full visibility into the sources behind every recommendation.

Westlaw Brief Builder

Build litigation briefs from issue framing to argument structure, all grounded in Westlaw and Practical Law authority. The attorney stays in control, reviewing facts, choosing arguments, attaching relevant authority, and validating the draft and citations to build briefs faster under tight deadlines.

Integrated end-to-end drafting 

CoCounsel Legal drafts directly in Microsoft Word, reading source documents in your matter — complaints, exhibits, agreements, and precedents — to pull key facts and defined terms, redline against your standard, and cite controlling authority automatically. Practical Law's model language and how-to guidance shape the draft from the start, so every section reflects current industry standards.

Use CoCounsel within Microsoft 365

Because CoCounsel Legal is built into the Microsoft Suite tools your team relies on every day — Word, Outlook, and beyond — the work happens inside your current workflows, with no new platforms to learn.

Incorporate your internal content with DeepJudge

DeepJudge unites an organization's own content systems into a single, secure search experience — giving legal professionals access to proprietary knowledge alongside CoCounsel Legal's authoritative content. The result is work grounded in the most relevant internal and external sources.

Connect your case files with Smokeball

For many small to midsize firms, Smokeball is the system of record for every case file. CoCounsel Legal extends the value of that case information by connecting matter documents to AI-powered research, drafting, and analysis, helping you move from information to action with less manual effort.
