  • Human-in-the-Loop

FEATURED CASE STUDY · PRODUCTION LEGAL AI

From First Contact to Attorney Review: Human-Governed AI Intake

AI-assisted intake across voice, email and documents, connecting first contact to attorney and case-manager review.

The engineering spans document intelligence, permission-aware workflows, Microsoft Graph and SharePoint integrations, background processing and human approval before consequential execution.

ACCESS

AI retrieves, organizes and understands information.

RECOMMEND

AI proposes actions or conclusions with supporting context.

EXECUTE

Approved actions use controlled tools, with an audit trail.
