Our verdict on West km
West km is Thomson Reuters knowledge management software for law firms and legal organizations. It searches an organization’s stored legal work product, including briefs, pleadings, memos, agreements, forms, and regulatory filings. Its strongest fit is for legal teams that already work with Westlaw and want one search experience spanning internal documents and external legal research. Web and Windows access support common desktop and browser-based workflows.
The product’s standout feature is the connection between firm content and Westlaw through WestSearch. Intelligent document search uses proprietary algorithms, while search results can include document summaries. KeyCite citation status flags and links add research context, and Locate Precedent retrieves sample agreements and related clauses. Together, these features support content reuse workflows: attorneys can find prior work, review related authority, and locate language for new documents. Integrations with Drafting Assistant, Microsoft Word, and Corel WordPerfect extend that workflow into document preparation.
West km is priced through contact sales, so buyers should evaluate it as part of a Thomson Reuters legal research and drafting environment rather than as a standalone, self-serve tool. It should suit firms that value internal precedent retrieval, citation linking, and close Westlaw alignment. Organizations requiring AI assistance or access controls should consider alternatives. West km is most compelling when a firm’s priority is finding and reusing its own legal work product alongside Westlaw content.
