LOIS, the Legal Operating Intelligence System, is the first AI purpose-built to run the modern law firm. Developed by Filevine and grounded in a decade of structured legal data across more than 40 million matters, LOIS goes beyond retrieval and summarization to take real action: creating tasks, setting deadlines, drafting documents, and executing work across the firm on behalf of its users. Unlike legal AI tools that assist a single user on a single task, LOIS runs AI agents across every matter and role in the firm, answering any plain-English question drawn from the firm's complete operation and writing results back to the system of record. Every claim is cited to its source document. Every action carries a deep link to what changed. LOIS is available now, with billing, payments, case law search, and skills-based workflows coming soon. Filevine is headquartered in Salt Lake City, Utah, with offices globally, and has served as a legal work platform for over a decade. Trusted by legal teams across law firms, global enterprises, and government agencies, Filevine has been recognized by the LegalTech Breakthrough Awards, The SaaS Awards, the Deloitte Technology Fast 500, and the Business Intelligence AI Excellence Award. With over $400 million in funding, Filevine developed LOIS as the central intelligence layer of its platform, integrating AI natively across case management, document automation, compliance, and analytics. Key features include: Conversational AI workspace: Legal teams can ask questions and draft documents directly from live case files, notes, calendars, and custom fields. Plus, every AI-generated answer comes paired with source citations and excerpted evidence for instant verification. Intent-aware query routing: LOIS automatically identifies what each request is asking for and directs it to the AI capability best suited for that task, whether that's summarizing a deposition, pulling out key facts, or calculating a jurisdiction-specific deadline. That means faster, more accurate answers, without any extra effort on your end. Automatically track deadlines: Timely lets you automate deadline tracking based on jurisdiction-specific rules, reducing the risk of missed critical dates across active matters. Medical record keeping: MedChron transforms your medical records into searchable, exportable chronologies, built to meet SOC 2 and HIPAA compliance standards. LOIS for Word: AI-native drafting and contract redlining, extended directly into Microsoft Word. Now, attorneys can work within familiar tools while still maintaining connectivity to case data. One of the biggest barriers to adopting AI in legal work is trust. Specifically, not being able to trust that the outputs actually reflect your firm's own cases, documents, and workflows. LOIS solves this by grounding every interaction in your firm's real data, so it works as a single source of truth rather than just another disconnected tool. Legal professionals can see exactly where answers come from, audit AI outputs when needed, and stay accountable at every step. Whether you're a solo firm, an in-house legal department, or a government agency, LOIS is built to standardize how your team works and consolidate everything into one place.
