Clearbrief AI features and pricing (October 2026)

Clearbrief is a Microsoft Word add-in for litigators and other legal writers. It checks the citations and factual claims in a brief against case law and the case record, and links each statement to its source before filing.

Clearbrief runs inside Word and covers drafting support for briefs, motions and arbitration filings. It creates hyperlinked citations, tables of authorities, hyperlinked PDFs, timelines and evidence tables, and it can review an opponent's brief for errors. It connects to sources and systems such as LexisNexis, Fastcase, Clio, NetDocuments, Relativity and PACER, and offers bring-your-own-storage options. The company lists a Seattle address. According to the vendor, users include litigators at large US firms, arbitrators, courts and in-house teams, and Microsoft Legal. Licenses run as an annual subscription, with a per-user Solo plan and a volume-based Enterprise plan, and the vendor offers one-to-one training for team onboarding.

• Links claims to the recordFact-Cite reads the evidence documents loaded for a matter and connects each factual statement in the draft to the page that supports it. Lawyers see at a glance which statements lack support, and spend less time hunting for exhibit pages.
• Checks legal citationsThe tool compares citations and quotations in a brief with the underlying decisions, flags inaccurate quotes and formatting errors, and links each authority to its source. The vendor describes this as deterministic AI rather than generative AI, so the team gets a check without invented cases.
• Builds tables and timelines from evidenceTable Builder and the timeline function extract facts, dates and quotes from records and assemble them into tables, chronologies and summaries with hyperlinked citations. Case teams get a working overview of a large record without retyping it by hand.
• Generates tables of authoritiesThe add-in collects the authorities cited in a document and creates the table of authorities automatically. Paralegals avoid a slow manual task before a filing deadline and can rebuild the table after late edits.

• Works inside Microsoft Word, so drafting and checking happen in the same document.
• The vendor states documents are never used to train models and offers bring-your-own-storage options.
• Integrations list includes research, practice management and e-discovery systems such as Clio, NetDocuments and Relativity.

The vendor lists an address in Seattle, Washington, and names AmLaw 10 and 200 firms, US federal and state courts and the American Arbitration Association as customers.

Check how your matter data is stored: the vendor mentions bring-your-own-storage, but hosting regions, subprocessors and a data processing agreement were not stated on the pages we reviewed in October 2026. For US litigation, confirm court rules on AI use and certification of filings, such as Rule 11, and any local standing orders. Clarify the number of licensed users, since the public price is per user.
