No training on your matter data
Nexum’s marketing promise is simple: customer matter data is not used to train models. Matter work stays tied to your firm’s workspace and approved workflows.
Security and supervision
Built for private matter data and attorney-supervised AI
Nexum is designed around the way legal teams handle sensitive matter data: source-backed outputs, attorney review gates, tenant separation, role-based access, and clear approval points before work product leaves the workspace.
For solo, small, and mid-sized firms, trust is practical. Your team needs to know where facts came from, who approved the output, and how the platform is configured around your firm’s supervision model.
How Nexum configures to your firm
Configure the workflow around your firm's standards.
Tenant isolation and roles
Firm workspaces, user roles, permissions, and matter access are configured so attorneys and staff see the work they are supposed to supervise.
Source citations and confidence
AI-assisted summaries, flags, drafts, and briefs are tied back to documents, pages, source quality, confidence signals, and review state.
Audit trail and review gates
Generated work product remains behind approval gates until an attorney or authorized reviewer decides it is ready to export, send, file, or use with a client.
Attorney review and supervision
Attorneys stay in control.
Nexum is not autopilot for legal work. The product is configured so legal teams review cited facts, approve generated work product, and control what leaves the workspace.
