LOIS, the Legal Operating Intelligence System, is an AI platform developed by Filevine, built on the company's structured legal data spanning more than 40 million matters and over a decade of development. The platform reads across a firm's matters, contacts, documents, deadlines, and data, and performs actions such as setting tasks, moving deadlines, generating documents, and writing results back to the system of record. It is designed for use by solo firms, in-house legal departments, and government agencies, and centralizes case data, documents, and workflows within a single system. Outputs are grounded in a firm's own case data and include citations to source documents for verification.
Key features and functions include:
Conversational AI Workspace
Enables legal teams to ask questions and draft documents directly from case files, notes, calendars, and custom fields. AI-generated answers include source citations and excerpted evidence for verification.
Intent-Aware Query Routing
Identifies the type of request being made and directs it to the AI capability suited to that task, such as summarizing a deposition, extracting key facts, or calculating a jurisdiction-specific deadline.
Automated Deadline Tracking
Timely tracks deadlines based on jurisdiction-specific rules to reduce the risk of missed dates across active matters.
Medical Record Keeping
MedChron converts medical records into searchable, exportable chronologies.
LOIS for Word
Provides AI-assisted drafting and contract redlining within Microsoft Word, maintaining connectivity to case data while working in that application.
