Clearbrief

Clearbrief is a legal AI platform that lives inside Microsoft Word and is built around one job: proving that the citations in a brief or motion actually support what the draft says. It describes itself as the leading cite checking platform in legal, and as the only platform that systematically checks citations to both the law and the facts without generative AI, using deterministic, rule based checking that cannot hallucinate. For litigation teams worried about fabricated authorities slipping into signed filings, that verification first design is the whole pitch. The checking is tied to visible sources. Clearbrief automatically links and displays the law cited in a draft through LexisNexis for mutual subscribers or Fastcase vLex for everyone else, and fact sources display through integrations with systems such as Relativity, iManage, and NetDocuments. It flags the widest variety of citation errors, links every citation for colleagues inside Word or in a hyperlinked PDF for the court, and can analyze an opposing brief the same way after converting its PDF to Word. Its patented Add Fact Cite tool finds evidence a draft did not cite. The vendor says approximately 70 percent of the AmLaw 20 use Clearbrief, that it is the official cite checking tool of the American Arbitration Association, and that millions of citations have been checked with it since launch; those figures are the vendor's own. From those source links, Clearbrief builds the filing package: instant Tables of Authorities, exhibits that update dynamically as the draft changes, timelines, fact sections, and summaries with clickable cites. A curated set of generative AI workflows covers timelines, summaries, document questions, investigation reports, and fact sections, always with hyperlinked sources so reviewers can check the output. At filing time, a final cite check creates an audit trail that helps every signing attorney certify they reviewed the cited sources, which the vendor frames around Rule 11 and newer state requirements. Security is SOC 2 Type II certified, customer documents are not used to train models, and firms can control whether generative AI is used at all. Pricing is published in a pricing section on the homepage. A solo plan is priced per user per month on an annual, license based subscription, with lower pricing mentioned for multi year agreements, while an enterprise unlimited plan is custom priced with volume discounts and one to one training included. Small firms can get Clearbrief from the Microsoft AppSource store. No prices are printed in this description; confirm the current figures with Clearbrief before subscribing.
