The first product from Brevyn Systems
Legal OS: one private AI workspace for your entire legal practice.
Manage matters, documents, deadlines, clients, research, drafting and business operations in one connected system — with AI designed to run within infrastructure you control.
Legal OS is currently in development. The capabilities below describe the product we are building, not a generally available product today.
[01]Why Legal OS
Built for legal work, not adapted from a generic chatbot.
Legal work is organised around matters, parties, documents, hearings, deadlines, research, precedents and professional responsibility. Legal OS connects these objects so AI can assist in context while the lawyer remains in control of the work.

[03]Who Legal OS is for
For law firms
Give teams a common operating system for matters and firm knowledge. Apply permissions around practice groups, matter teams, ethical walls and confidential engagements. Build more consistent processes without separating AI from the records and workflows it needs to understand.
For individual lawyers
Replace disconnected tools with one system for running a legal practice. Stay on top of clients, matters, documents and deadlines while using private AI assistance for search, summaries and drafting.
[04]Privacy
Private by design
Legal OS is designed for deployment within the firm's or lawyer's controlled environment, including on-premise or private-cloud infrastructure. Matter data is not intended to be pooled across customers or used to train shared models.
