ClearBrief was founded in Seattle and has raised $4 million to build AI tools that help lawyers find, verify, and insert factual citations in litigation documents. The platform has been adopted by major law firms including Dykema and Cozen O'Connor, as well as in-house legal teams at Microsoft, the Maricopa County Attorney's Office, and the American Arbitration Association. It was named 2025 Innovator of the Year by Legalweek.
ClearBrief operates as a Microsoft Word add-in and offers fact citation verification (linking factual assertions in a brief to supporting documents), AI-powered hallucination and citation checking via a LexisNexis integration, automated Table of Authorities generation, hyperlinked exhibits, and real-time trial support enabling live search and fact-checking during proceedings. The platform is specifically built for fact-intensive legal documents in litigation contexts.
Unlike general AI legal research tools, ClearBrief focuses narrowly on citation integrity and fact verification within documents already being drafted — it does not replace primary research tools but functions as a quality-control layer on top of them. This document-centric approach sets it apart from platforms like Westlaw or LexisNexis, which are external research databases.
Best fit: Litigators at mid-size to large firms who draft high-volume fact-intensive briefs, in-house teams reviewing litigation documents, and arbitrators or courts handling document-heavy proceedings. At $300/user/month, it is an add-on budget item rather than a primary research platform.
