Arivu is a matter-focused legal intelligence system designed to operate within an organization’s Microsoft 365 tenant. It reviews documents for unusual or high-risk clauses and pulls out dates, parties, and financial obligations. For drafting, it follows an organization’s previous style and formatting, with suggestions linked to internal material or external case law. Arivu can also analyze a matter folder as a dataset to find deviations and inconsistencies among related documents. Multi-step playbooks support repeatable work such as NDA review and M&A due diligence. The product is delivered in Microsoft Word, Outlook, Teams, and SharePoint Online, and uses CourtListener for public case law. Arivu says its answers draw on firm documents and CourtListener, which it describes as containing more than 400 million public court records. Entra ID delegated permissions and Microsoft Graph restrict processing to files users can access. The company says analysis runs in volatile memory, customer documents are not used to train models, and it keeps no text chunks or embeddings on its own disks. Pricing is available on request.
