The Legal agent was previously released in Frontier preview for users located in the United States only. This update expands access globally, enabling more organizations to benefit from this capability.

The Legal agent is a vertical-specific Microsoft 365 Copilot experience designed for legal professionals, built directly into Word. It helps legal teams review and negotiate contracts by identifying risks, comparing clauses to internal playbooks, and proposing edits using Word’s native tracked changes.

This update helps reduce manual review time while keeping legal professionals fully in control of document workflows.
